The Environmental requirements section on page 1-5 should be observed to ensure the optimum

operation of the printer. The use of the printer in a location which does not satisfy the requirements

may result in troubles and risk shortening its service life.

The printer will work best if it is installed in a location that is:

• Level and well supported (Place the printer on a table or desk.)

• Not exposed to sunlight or other bright light (not next to an uncurtained window). Do not place

the printer on an unstable cart, stand or table.

• Near an AC wall outlet, preferably one that can be used for the printer alone. The outlet should

have a ground slot, or an adapter should be used. If you use an extension cord, the total length of

the power cord plus extension cord should be 17 feet or 5 meters or less.

• Well ventilated, not too hot or cold, and not too damp or dry (See section Environmental

requirements on page 1-5). If you install the printer where the temperature or humidity is outside

the requirements in section Environmental requirements in chapter 1, the best print quality may

not be expected and there will be an increased chance of paper jams.

• Provide a sufficient clearances around the printer to ensure ventilation and ease of access. (See

section Clearance on next page).

2-2-3 Developer initialization (automatic)

The printer is shipped from the factory with no toner installed in the developer. In order for the

printer to be operable, the developer must be filled with a sufficient amount of toner necessary to

continuously support print jobs. This is called developer initialization and automatically executed

when the printer is turned on for the first time. Developer initialization takes up to 15 minutes for

the original developers (DV-60 for the FS-1800 and DV-61 for the FS-3800) or 8 minutes for the

service developer (DV-62 for both models).

NOTE Do not turn printer power off during the developer is initialized. If the printer is

switched off in the middle of developer initialization, even after the printer is

switch on again, the printer will not automatically resumes developer

initialization. Should this be the case, enforce the printer to resume developer

initialization in the following manner:

1. While the printer is turned off, press and hold the GO and CANCEL keys.

2. Turn printer power on.

3. Let go off of the GO and CANCEL keys for more than 5 seconds.

Developer initialization resumes for the rest of the required total time.

4. Wait until the READY indicator is lit and the message display indicates Ready.

5. Make a test print by printing a status page. To print a test page, proceed as follows;

1 Press the MENU key on the printer.

2 Press the key or key repeatedly until the message display shows Print Status

Page.

3 Press the ENTER key twice.

6. If the status page is printed satisfactorily, setup is complete. If not, investigate whether all step

procedures are properly followed.

(5) Replacing the waste toner bottle

Note that the printer has a sensor to monitor the presence of the waste toner bottle. The printer does

not operate without a waste toner bottle installed.

For the reference, the waste toner bottle can hold up to 100 g of waste toner. The nominal amount

of waste toner derived after 10,000 pages of printing is 20 to 30 g (Letter or A4 size paper; average

print coverage of 5 %).

Open the side cover. While holding old the waste toner bottle 1, press the lock lever 2 in the

right ward direction. Then gently pull out the waste toner bottle 1. Close the cap 3 of waste toner

bottle 1 after removing from the printer. To avoid toner spilling, place the capped waste toner

bottle 1 in the plastic bag 4 supplied before forwarding to proper disposal.

Locate the new waste toner bottle in the toner kit, and install it in the printer according to section 2-

(5) Developer initialization (Feeding toner into the new developer)

The new developer unit is shipped from the factory with no toner contained. The developer can be

automatically replete with toner when a toner container is installed onto it and the printer is turned

on. However, because the toner reservoir in the developer has a large capacity, it requires a lengthy

period of time until a substantial amount of toner has been fed to get the printer ready. (A new

developer needs approximately 100 g for triggering the sensor inside.)

A great many seconds of time for this is greatly deducted by using the service menu in the printer’s

mode select routine as accessed by its operation panel. Follow these steps to use this feature, top to

bottom (For details, refer to section 2-3 Using the operator panel on page 2-19).

Electrophotography is the technology used in laser printing which transfer data representing texts

and graphics objects into a visible image which is developed on the photosensitive drum, finally

fusing them on paper using the light beam generated by a laser diode.

This section provides technical details on the printer’s electrophotography system.

4-1-1 Electrophotographic cycle

The electrophotographic system of the printer performs a cyclic action made of six steps as follows.

Each step is technically explained in the following sections.

Amorphus-silicon drum

The printer use the long lasting amorphous silicon drum. The drum surface is a composite of five

substances coated in five layers as shown below.

Figure 4-1-3 Amorphus silicon drum

The primary and secondary layers are for protecting the amorphous silicon layer underneath. The

amorphus silicon layer is of photoconductive, meaning it can be electronically conductive when

exposed to a (laser) light source to effectively ground electrons charged on its outer surface to the

ground. This layer is approximately 9 µm thick.

The carrier block layer lies between the amorphous silicon layer and the aluminum base cylinder

and prevents the backward electron flow, from the base cylinder to the drum’s outer surface, which

might give adverse effect (possibly “ghost”) on the print quality.

Charging the drum

The following shows a simplified diagram of the electrophotographic components in relation to the

engine system. Charging the drum A is done by the main charger wire B.

Figure 4-1-4 Charging the drum

As the drum A rotates in a “clean (neutral)” state, its photoconductive layer is given a uniform,

positive (+) corona charge dispersed by the main charger wire B. The grid C regulates the main

charging potential so that it is evenly and stably dispersed over the drum A at a constant voltage

level.

Due to being high-voltage scorotron charging, the main charger wire B can get contaminated by

oxidization after a long run. Therefore, it must be cleaned periodically from time to time using the

method explained in chapter 3, page 3-9. Cleaning the main charger wire B prevents print quality

problems such as black streaks.

Name Description

5 Primary f-theta lens See figure 4-1-7 below.

6 Secondary f-theta lens The primary (above) and secondary f-theta lenses equalize focusing

distortion on the area on the drum closer to the edge. The effective

length of line (A, B in the figure below) the laser beam draws on

the drum becomes longer as the laser beam hits closer to the drum

edge. In the figure 4-1-7 below, distances represented by A and B

are not the same (A > B) until the f-theta lenses are provided between

the polygon mirror and the drum (A = B).

7 Diversion mirror Diverts the laser beam vertically onto the drum. Note the diffused

laser beam finally pinpoints on the drum.

8 Protective glass Prevent dust, debris, etc., from entering the scanner assembly.

9 Sensor mirror Bends the very first shot of a laser scan towards the pin photo sensor

(below).

0 Pin photo sensor When shone by the sensor mirror above, this pin photo sensor

generates a trigger signal.

Drum surface potential

The laser beam is continually switched on and off depending on the print data. It is on for a black

(exposed) dot and off for a white (blank) dot. Since the drum surface is evenly charged, whenever

it is illuminated by the laser beam, the electrical resistance of the photoconductor is reduced and the

potential on the photoconductor is also lowered. Resulted on the drum surface is an electrostatic

image which represents the data to print. Note that the area to be printed black has the low potential,

constituting a “positively exposed” image.

4-12FS-1800/1800N | FS-3800/3800N

The latent image constituted on the drum A is developed into a visible image. The developing

roller B contains a 4-pole (S-N-S-N) magnet core C and an aluminum cylinder rotating around

the magnet core C. Toner attracts to the developing roller B since it is powdery ink made of black

resin bound to iron particles. Blade D magnetized by magnet E is positioned approximately 0.3

to 0.4 mm above the developing roller B. It constitutes a smooth layer of toner in accordance with

the revolution of the roller.

Figure 4-1-10 Development

The developing roller B is applied with the AC-weighted, positive DC power source. Toner F on

the developing roller B is given a positive charge. The positively charged toner F is then attracted

to the areas of the drum A which was exposed to the laser light. (The gap between the drum A and

the developing roller B is approximately 0.3 mm.) The non-exposed areas of the drum A repel the

positively charged toner as these areas maintain the positive charge. The developing roller B is

also AC-biased to ensure contrast in yielding by compensating the toner’s attraction and repelling

action during development.

A toner sensor is provided within the developer. As the toner supply from the toner container

dwindles and the toner level lowers in the reservoir, the sensor translates it into an electrical signal

through its diaphragm, urging the toner motor to feed more toner.

(4) Transfer

The image developed by toner on the drum A is transferred onto the paper because of the electrical

attraction between the toner itself and the transfer roller B. The transfer roller B is negatively-

biased so that the positively-charged toner is attracted onto the paper while it is pinched by the

drum A and the transfer roller B.

Figure 4-1-12 Transfer

The nominal transfer bias is set to approximately -2.3 kV (limit) with the -65 µA current. Since the

ideal potential of the transfer bias depends on the thickness of paper, the bias is raised to approximately

-2.6 kV/-65 µA for thicker paper. On the other hand, the bias current is reduced to -2.1 kV/-65 µA

for thin paper.

(5) Fusing

The toner on the paper is molten by heat and pressed into the paper as it passes between the heat

roller A and the press roller B in the fuser unit.

Figure 4-1-13 Fusing

The heat roller A has a heater (infrared) lamp C inside which continuously turns on and off by the

thermistor to maintain the constant temperature on the heat roller A surface. The fusing temperature

is also controlled based on paper types. See the table in the figure above.

The heat roller A is florin coated by to prevent toner from accumulating on the roller after a long

usage. Care must be taken while handling the heat roller A not to scratch the roller surface as

doing so may result in quality problems.

The heat roller A has four scraping claws (Separators) D which are continuously in contact with

its surface. These claws prevent the paper on which toner has been fused from being wound around

the heat roller A causing paper jam.

The press roller B is made of the heat resistant silicon rubber. This roller is used to strongly press

the paper towards the heat roller A by means of coil springs.

The temperature of the heat roller A is constantly monitored by the engine board using the thermistor

and triac. Should the temperature of the heat roller A exceed the predetermined value, the thermal

cutout is activated to effectively disconnect the heater lamp C from power.

(6) Cleaning

After the transferring process, the drum needs to be physically cleaned of toner which is residual

after the development process. The cleaning blade A is constantly pressed against the drum B and

scrapes the residual toner on the drum off to the cleaning roller C. The cleaning roller drives the

toner to the cleaner screw D at one end of which the waste toner bottle is connected to collect the

waste toner.

Figure 4-1-15 Drum cleaning and erasing static charge

After the drum A is physically cleaned, it then must be electrically cleaned to neutral state. This is

necessary to erase any residual positive charges, ready to accept the next uniform charge. The

residual charge is canceled by exposing the drum A to the light emitted from the eraser lamp

[board] E (See figure 4-1-15 above.) in the similar manner as described on page 4-6. This lowers

the electrical conductivity of the drum A surface making the residual charge on the drum A

surface escape to the ground.

4-2 Paper feeding system

The paper feeding system picks up paper from the paper cassette, MP tray, or if installed, the paper

feeder PF-60, feeds it in the printer and delivers in the output tray. Paper is feed at the precise

timing in synchronization with data processing. The paper feeding system finally delivers the printed

page to either the face-down or face-up output tray as manipulated by the user.

The figure below shows the components in the paper feeding system and the paths through which

the paper travels. The sensors, clutches, solenoids, motor etc., are described in the following pages.

Eraser lamp control circuit

CPU (U201) turns on its #59 pin to H and turns Q215 and Q214 on. Current flows through Q214

and R249, then the eraser lamp, activating the lamp. Current also routes through R251 and R252 as

bled by R251. Point A below is approximately 14.5 V when the eraser lamp is normal. If the eraser

lamp blows out or the connector is not fitted, current goes through only R251 and R252, subsequently

the potential at point A is as high as approximately 24 V. Difference in the potential at point A

where the eraser lamp is normal or not is automatically detected as an error. When anomaly is

detected with the eraser lamp, the detector circuit turns Q216 on and turns ERDEAD* at #60 pin of

CPU (U201) to L. This in turn causes CPU (U201) to determine that the eraser lamp is faulty,

displaying Call service personE5.

Toner motor control circuit

As TMOTON at #15 of gate array (U204) turns to H, Q218 and Q217 turn on, and +24 V reaches

Q217, R265 and the toner motor, finally driving the toner motor.

If the toner motor is overloaded by some reasons, an overcurrent may flow through the toner motor

beyond the predetermined level, turning Q220 on. Q220, when turned on, causes the current from

the +24 V power supply to flow through Q217, Q220, R267, R268, and to the ground. Consequently,

approximately 3.9 V (H) develops at point A, as limited by the combination of R267, R268, and

DZ206. This voltage is used as TNMOC - toner motor error - which is applied to #17 of CPU

(U201). Thus, CPU determines the toner motor error and lets Call service person E9 be

indicated.

Heater lamp control circuit

The heater lamp control circuit turns the heater lamp on and off which is located coaxially inside

the heat roller. The surface of the roller maintains the constant temperature needed to permanently

fuse the toner on paper.

The heater lamp is directly fed with AC primary power (120 V or 220 - 240 V) which is supplied

from the power supply unit.

4-32FS-1800/1800N | FS-3800/3800N

As change in temperature is detected by the thermistor, CPU U201 adjusts the voltage that is

resultant of change in temperature, given at pin #3 (THERM) to keep the temperature as constant as

possible. This voltage is used to continuously switch the fuser lamp on and off. If pin #4 (HEATON)

of the engine gate array U204 is H level, transistor Q204 (pin #2) turns on, the photo coupler (PC)

on the power supply unit turns on, and the triac (TRC) turns on, consequently the heater lamp is AC

powered and lights. The heater lamp continuously turns on and off to maintain the temperature on

the heater roller at approximately 185*1/200*2 °C (Normal paper, A4), 175*1/190*2 °C (Thin paper,

A4), and 190*1/205*2 °C (Thick paper, A4) for printing and approximately 95 °C at standby (Ready).

Refer to section Fusing on page 4-15. *1: FS-1800/1800N *2: FS-3800/3800N

Abnormal temperature detection circuit

The thermal cutout device which is connected in series with the heater lamp, constitutes the the

abnormal temperature detection circuit including of comparators U205-2, R217, R219, etc. Pin #5

of the comparator U205-2 is continuously given with the voltage by resistors R217 and R219,

which simulate the voltage given if an abnormally high temperature develops. Pin #6 receives the

voltage the thermistor detects. For instance, the heater lamp happens not to switch off, the voltage

the thermistor gives at pin #6 will become unusually high, and as soon as it exceeds the voltage at

pin #5, pin #7 of the comparator U205-2 output changes to L level. This in turn turns transistors

QA201B and QA201A on, and turns QA201A (pin #6) to L level. Since pins #6 of the transistor

QA201A and #2 of transistor Q204 are connected to each other, pin #4 of the engine gate array

U204, even though it is currently at H level, is enforced to be H level, effectively disabling the

heater lamp. Pin #7, the output from comparator U205-2, changes to L. Then, it is output to #63 of

CPU (U201) which in turn determines that an unusual temperature has developed in the fuser,

indicating Call service personE4.

Thermistor blown-out detection

The thermistor is monitored by the combination of comparator U205-1, R233, and R238. Extremely

low potential is applied to pin #3 of U205-1 by means of R233 and R238. Whereas, pin #2 is

applied with the voltage the thermistor detects. In normal state, as the heater lamp glows, the voltage

detected by the thermistor is greater than the potential at #3 of U205-1, making the U205-1 output

to L and sent to #54 (THDEAD) of CPU.

When the thermistor has blown, pin #2 of U205-1 becomes zero which is well lower than the

potential at pin #3 of U205-1, the comparator output becomes H, delivering THDEAD at pin #54 of

CPU. CPU uses this signal to determine that the thermistor is faulty and displays Call service

personE4.

(3) Sensor board

Paper gauge sensing circuit

Paper gauge operates in four levels of paper remaining in the cassette. The height of the paper stack

in the paper cassette changes the angle of the actuator. At the end of the actuator is a reflecting

mirror which reflects or interrupts the light emitting from photointerruptor sensors PH702 and

PH703 accordingly.

These two sensors generate four digital signals which will be digital-analog-converted and input to

A/D port of CPU. CPU then issues signals according to the level of the analog signals. The resultant

signals are used to monitor the amount of paper in the cassette through the network management

utilities.

The interlock circuit is constituted by SW702, the top cover/paper feed unit interlock, and SW703,

the side cover interlock, both mounted on the sensor board. These switches are controlled by the

actuator which is mechanically activated by the projection on the top cover and the feed unit.

SW703 and SW702 are connected in series to the +24 V power. Physically opening the top cover,

side cover, or the paper feed unit will disconnect the +24 V power, signaling the status to the engine

board. The top cover switch (SW701) serves only the top cover.

5-1 General instructions

This chapter provides the procedure for removal and replacement of field replacement components.

For other components not explained in this chapter, it is recommended that your refer to the diagrams

in the Parts Catalog as a supplemental reference to this chapter. It features all the part drawings and

help you disassemble or refit the parts in the printer.

When replacing of a component, reverse the procedure for the removal procedure explained in this

chapter.

WARNING To avoid injury caused by electric shock, make sure that AC power is removed

and the power cord is unplugged from both the power line and the printer.

5-1-1 Screw/hardware

Screws and hardware used in the printer are listed in the Ecosys Screw catalog. These screw symbol

numbers are universal to most Ecosys printers.

CAUTION When securing a self-tapping screws, align it with the thread carefully. First turn

it counterclockwise, then slowly clockwise. Do not overtighten. In case the self-

tapped thread is damaged, the whole part may have to be replaced with a new

part.

5-1-2 Before starting disassembly

Before proceeding, unplug the power cord from the printer and the power supply.

WARNING Never attempt to operate the printer with components removed.

CAUTION The printer use electrostatic sensitive parts inside (circuit boards, laser scanner

unit, etc.). Provide an antistatic (discharging) device, such as a wrist strap, that

can effectively discharge your body before touching those components.

(3) Dropouts

Note the spacing of the defects. Refer to Repetitive defects gauge. See page 6-47.

• If the defects occur at regular intervals of 39 mm, the problem may be the damaged developing

roller (in the developer). Replace the developer. See page 3-13.

•If the defects occur at regular intervals of 94 mm, the problem may be the damaged drum (in the

drum unit). Replace the drum unit. See page 5-12.

•If the defects occur at regular intervals of 72*1/94*2 mm (heat roller) or 79 mm (press roller), the

problem may be the damaged fuser unit. Replace the press roller or heat roller. See page 5-34 or 5-

36. *1: FS-1800/1800N *2: FS-3800/3800N

Check paper property.

• Paper with rugged surface or dump tends to cause dropouts. Replace paper with the one that

satisfies the paper specifications.

Check the transfer roller installation.

• The transfer roller must be supported by the bushes at the both ends. Clean the bush to remove oil

and debris. Replace the transfer roller if necessary. See page 5-17.

Check the transfer bias potential.

• Check the transfer bias output on the high voltage unit. This requires removal of the left cover and

the test equipment. Replace the high voltage unit if high voltage potential is not available on the

board. See page 5-25.

(4) Black dots

Note the spacing of the defects. Use the Repetitive defects gauge. See page 6-47.

• If the defects occur at regular intervals of 94 mm, the problem may be the damaged drum (in the

drum unit). Replace the drum unit. See page 5-12.

• If the defects occur at random intervals, the toner may be leaking from the developer and drum

unit. Replace the developer and drum unit. See page 5-4 and 5-12.

(5) Black horizontal streaks

Check the drum unit’s ground.

• The drum axle in the drum unit and its counter part, the grounding tab in the printer, must be in a

good contact. If necessary, apply a small amount of electro-conductive grease onto the tab.

The drum may be defective.

• Replace the drum unit. See page 5-12.

Contaminated main charger wire.

• Clean the main charger wire by pulling the green colored cleaning knob in and out several times.

See page 3-9.

Check the drum surface for a streak of toner laying lengthwise.

• A streak of toner remaining on drum after printing means that the cleaning blade (in the drum unit

) is not working properly. Replace the drum unit. See page 5-12.

Defective magnet roller (in the developer).

• Replace the developer. See page 5-4.

(7) Unsharpness

Check paper for property.

• Paper with rugged surface or dump tends to cause unsharp printing. Replace paper with the one

that satisfies the paper specifications.

Check the transfer roller installation.

• The transfer roller must be supported by the bushes at the both ends. Clean the bush to remove oil

and debris. Replace the transfer roller if necessary. See page 5-17.

Check the transfer bias potential.

• Check the transfer bias output on the high voltage unit. This requires removal of the left cover and

the test equipment. Replace the high voltage unit if high voltage potential is not available on the

board. See page 5-25.

Check EcoPrint setting.

• The EcoPrint mode can provides faint, unsharp printing because it acts to conserve toner for draft

printing purpose. For normal printing, turn the EcoPrint mode off by using the operator panel. For

details refer to the printer’s User’s Manual.

Check the print density setting.

• The print density may be set too high. Try adjusting the print density using the Remote operation

panel utility. For details refer to the printer’s User’s Manual.

Check the surface potential of the drum (in the drum unit).

• The drum potential should be approximately 230±15 V. This may vary depending on production

lots. Measurement is possible only by using the jig and tool specifically designed for this purpose.

The drum unit will have to be replaced if it bears values far out of the allowable range.

Check the grid.

(9) Dirt on the top edge or back of the paper

Check toner contamination in various parts.

• Dirty edges and back of the paper can be caused by toner accumulated on such parts as the paper

chute, paper transportation paths, the bottom of the drum and developer, and the fuser unit inlet.

Clean these areas and parts to remove toner.

Check the transfer roller.

• If the transfer roller is contaminated with toner, clean the transfer roller using a vacuum cleaner;

or by continuously printing a low-density page until the symptom has faded away.

Parallel interface

The printer uses a bidirectional parallel interface for high-speed data transmission for the host

computer. This interface includes the buffers which are compatible with the IEEE 1284 standards.

The parallel interface provides support for the ECP and nibble modes in this standards. The parallel

interface mode can be changed by commanding Prescribe commands on a PC.

Selecting the parallel interface mode

To change the parallel interface mode, a PC running MS-DOS is needed. Connect the printer to the

PC via the parallel interface. Then, at the DOS prompt, type a FRPO O0 (the letter O and the

number zero) command as follows depending on the desired parallel mode:

To set the parallel interface mode... Type at the DOS prompt...

Parallel interface signals

The following table provides details for the signals used on the printer’s parallel interface. Note

descriptions in [ ] are for high-speed mode of the parallel interface.

Signal Meaning

A negative-going Strobe* pulse causes the printer to read and latch

the data on the Data 0 [1] to Data 7 [8] signal lines.

These eight signals form the data byte sent from the host computer to

the printer. Data 7 [8] is the most significant bit and Data 0 [1] is the

least significant bit.

This signal is returned to the host computer. This negative-going pulse

acknowledges the previous character received by the printer.

Acknowledge* pulses are sent only when Busy is low.

This signal is returned to the host computer. This signal is high when

the printer is busy and low when it is able to accept more data. Every

high-to-low transition is followed by an Acknowledge* pulse.

This signal is returned to the host computer. This signal goes high

when the printer runs out of paper.

This signal is returned to the host computer. This signal is high when

the printer is on-line and low when the printer is off-line. It goes low

when the upper unit is raised, or when the GO key is pressed to set the

printer off-line.

Note: The Paper Empty and On-Line signals are not used unless enabled

by the FRPO command (O2 parameter).

This signal is used in the Epson version of the Centronics interface to

receive a carriage return. In high-speed mode, it is used as an interrupt.

This line is connected to the printer’s +5 V DC line (+5 V ±0.5 V, 500

mA maximum, fused).

This signal is used in the standard Centronics interface to enable the

computer to reset the printer. It is ignored by the printer.

When the high-speed parallel line control is on (FRPO O2 = 2), this

line returns error status to the host computer.

This signal line is not used.

This signal is high when the printer’s power is on.

This signal is used in some versions of the Centronics interface to

enable the computer to force the printer on-line. In high-speed mode,

it is used as an interrupt.

C-6FS-1800/N | FS-3800/N

Serial interface

The printer is equipped with a serial interface connector. The device responsible for controlling the

serial interface is integrated in the gate array in the controller system. The serial interface supports

protocol of RS-232C. A 25-pin D-sub connector is used for the serial interface.

RS-232C interface voltage levels

The voltage levels of the RS-232C signals conform to EIA RS-232C specifications. FALSE is from

3 volts to 15 volts. TRUE is from -3 volts to -15 volts. Voltages between -3 volts and 3 volts are

undefined.

Connector configurations

The printer uses a DB-25 connector for the serial interface. Depending on the computer configurations

for serial interface, use either of the appropriate configurations.

Signal Meaning

FG (Pin 1) This pin is connected directly to the printer frame.

TxD (Pin 2) This output carries asynchronous data sent by the printer to the computer.

It is used mainly in handshaking protocols.

RxD (Pin 3) This input carries serial asynchronous data sent by the computer to the

printer.

RTS (Pin 4) This output is always held high (above 3 V).

CTS (Pin 5) Unused.

DSR (Pin 6) Unused.

SG (Pin 7) All signals can transmit between the printer and the host computer to send

each signals with a signal ground.

+5V (Pin 12) Power supply for barcode reader. (Maximum 500 mA)

DTR (Pin 20) This output is used as a buffer nearly-full handshake line. It is held high

(above 3 V) when the buffer can accept more data.
