Precautions

Service Manual

1.3 ESD Precautions

Certain semiconductor devices can be easily damaged by static electricity. Such components are commonlycalled “Electrostatically Sensitive (ES) Devices”, or ESDs. Examples of typical ESDs are: integrated circuits,some field effect transistors, and semiconductor “chip” components.The techniques outlined below should be followed to help reduce the incidence of component damage causedby static electricity.

Caution >>Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

1. Immediately before handling a semiconductor component or semiconductor-equipped assembly, drain off

any electrostatic charge on your body by touching a known earth ground. Alternatively, employ a commer-

cially available wrist strap device, which should be removed for your personal safety reasons prior to apply-

ing power to the unit under test.

2. After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface,

such as aluminum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity

of the assembly.

3. Use only a grounded tip soldering iron to solder or desolder ESDs.

4. Use only an “anti-static” solder removal device. Some solder removal devices not classified as “anti-static”

can generate electrical charges sufficient to damage ESDs.

5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to

damage ESDs.

6. Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most

replacement ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a

comparable conductive material.

7. Immediately before removing the protective shorting material from the leads of a replacement ESD, touch

the protective material to the chassis or circuit assembly into which the device will be installed.

8. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed,

until completely plugged or soldered into the circuit.

9. Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as the

brushing together of clothing fabric and lifting one’s foot from a carpeted floor, can generate static electric-

ity sufficient to damage an ESD.

1) Charging Voltage: Charger* Function : This high voltage is used to charge the surface of the OPC to about -500volt~800volt.* Output voltage : -1.0KV~-2.0KV DC °æ 50V* Error type :If MHV was not present, the surface of the OPC is not charged. As a result, toner on

the developer roller is transferred over to the OPC drum: therefore, black paper couldbe printed out.

2) Transfer high voltage: T1(+)* Function : This high voltage is used to transfer toner from the OPC drum to the ITB unit.* Output voltage : Max +2.0KV °æ 3% (Duty is changeable, no loading)* Error type : If T1 was not present, it is not possible to transfer toner from the OPC drum to the

ITB. As a result, printer output could be faint.

3) Transfer High Voltage: T2 (+)* Function : this high voltage is use to transfer toner from the ITB to the paper.* Output voltage : Max +5.0KV °æ 3% (Duty is changeable, no loading)* Error type : If T2 was not present, it is not possible to transfer toner from the ITB to the paper. As

a result, printing output could be faint

4) Cleaning voltage: T2 (-)* This high voltage is used to transfer (-)toner, remains on transfer roller, from the Transfer Roller

to the ITB unit.* Output voltage : There is no feedback control, and it outputs a fixed voltage (-120V).* Error type : Toner contamination occurs on the reverse side of the printed-paper.

5) Developing voltage: DEV* Function : This high voltage is used to develop toner due to a potential difference on the part

of the OPC exposed to the LSU (Laser Scanning Unit).* Generally, when printing, the exposed portion of the OPC is charged to -50 volt and the DEV is

at -350 volt: therefore, toner of (-) polarity is transferred onto the exposed section.* Output voltage : -200V~600DV DC20V* Error type : 1. In case that DEV is GND, density gets extremely low.

2. If DEV is floating due to an unstable contact point at the HV terminal, density getsextremely heavy.

6) Supplying voltage: Supply* Function : This high voltage is used to supply toner to the developer roller.* Output voltage : -400V~800V DC 50V (Using ZENER, DEV is connected)* Error type: 1. If this voltage is GND, print density is extremely low.

2. If this voltage is floating due to unstable contact point at the HV terminal, densitybecomes so low as that printing results are not visible to the naked eye.

2. Image Transfer Belt cleaner After the final image is transferred onto paper any wastetoner is removed from the transfer belt using this cleaningblade

3. PTL (Pre-Transfer Lamp) The primary image transfer to the ITB is made more efficientby the use of a PTL

4. CTD (Color Toner Density) sensor This sensor is used by the engine to monitor the density oftoner deposited on the OPC drum. It is also used as an indi-cation of 'Toner Empty'

5. Image Transfer Roller (T2 Roller) This transfers the final toner image on the image transfer beltto paper.

6. ITB Home Sensor This sensor is used to ensure that each of the 4 colorimages starts at exactly the same point on the ITB. It worksby detecting a fixed point on the belt.

4) CTD (Color Toner Density) SensorThe CTD sensor detects density of toner of each of the 4 colors formed on OPC drum, and CTDcontroller decides an optimum developer bias voltage value for printing.

* Structure: An Infrared LED is used as a sending unit and PDs (Photo Diodes) are used as areceiving unit. A PBS (Polarized) Bean Beam Splitter) is used to separate transmittedlight from the LED and reflected light from the OPC / toner surface.

* Principal: The OPC surface and toner have different light reflecting characteristics. The OPC surface produces a specular reflection whilst the toner produces a scattered reflection.By detecting this difference the amount of toner present on the OPC surface can bemeasured by the sensor.

* Caution: Be careful not to contaminate the surface of the CTD sensor, as this will cause problems with color reproduction and quality.

* Process: The TRC (tone reproduction Curve) control process is used at power on, after wakingfrom sleep mode , after every 100 pages of printing, and after replacing a developer bynew one to check the toner density transferred onto the OPC. Small patches of 6.25%,25%, 37.5%, 50%, 62.5%, 75%, 87.5%, and 100% density for each of the 4 colors aredeposited on the OPC drum surface and the CTD is used to detect how much toner istransferred. Based on an internal calibration curve the TCR control process adjusts thedeveloper bias voltage to ensure that optimal toner transfer takes place.

5) Secondary Image TransferThe image is built up on the ITB (primary image transfer). This image is then transferred onto paperusing the T2 transfer roller (roller transfer system) this process is known as the secondary imagetransfer.

* The HVPS applies the Image Transfer Bias voltage to the Image Transfer Roller (T2), thistransfers the image from the belt onto the paper.

* When the image is to be transferred from the ITB to the paper the image transfer rollerpressure contact solenoid is activated and this activates a cam which moves the T2 rollerinto contact with the belt.

*After the transfer has taken place any remaining charge on the paper is removed byapplying a charge removal bias (generated in the HVPS) to a charge removal plate

5.1.5 Fuser (Fusing Section)

Toner that has been through the primary and secondary image transfer processes is fixed, semi-permanently, to the paper.The fuser unit consists of heat lamps (2 ea), heatrollers (2 ea), thermistor, and thermostats (2 ea). Itmelts the toner onto the paper using pressure and high temperature to complete the printing process.

1) Thermostat (2pieces)If the heat lamps or heat rollers overheat thethermistor turns off power to the lamps in thefuser unit to prevent fire. It is a temperaturecut-off device.

2) ThermistorThe thermistor detects the temperature of the heat roller's surface, and feedbacks the informationto the main processor which uses this information to control power to the fuser lamps in order tomaintain the heat roller at a steady temperature.

3) Heat Roller (2pieces)Halogen lamps are used to heat the heat rollers. The heat rollers have a special Teflon surfacewhich ensures that any melted toner which comes into contact with the heat roller surface does notstick. Paper passes between the two rollers which evenly heat the paper from both sides to meltthe toner and semi-permanently fix it to the paper.

4) Safety Information> Overheat protection

* 1st level protection: Print engine is stopped if overheat is detected* 2nd level protection: Software turns off lamp power if overheat is detected.* 3rd level protection: Thermostat turns off lamp power if overheat is detected.

> Protecting device* Fuser unit power is turned off when

the duplex cover or the toner cartridge door is open.

* This machine keeps the surface temperature of the fuser unit coverunder 80°C, and it has a cautionlabel attached inside the exit coverwhere it can be easily seen by the user.

Any static electrical chargeis removed by static discharge brushes.When operating in duplex print mode, after printing the front side of the page, the paper exit rollerreverses to feed the paper back into the machine in order to print the second side of the page.

5.1.7 Waste Toner Collection ProcessWaste toner on the OPC drum and on the image transfer belt is collected into the waste toner tank.* After transferring the toner image on the OPC drum to the ITB, a cleaning blade scrapes waste

toner from the OPC drum, and the waste toner is collected into a waste toner tank.* An Image Transfer Belt cleaner scrapes waste toner from the image transfer belt, and the waste

toner is collected into a waste toner tank.

1) Waste toner tank sensorA waste toner sensor detects the presence of the waste toner tank and also detects if the tank is full.This is an On / Off detection. Do not operate the printer without a waste toner tank.

> No waste toner tankWhen the waste toner tank is not installed the waste toner senoractuator blocks light from the senor LED.

> A little waste tonerWhen the sensor LED light reaches the photo sensor passingthrough the waste toner tank this indicates that the tank is not full.

> Waste toner tank fullWhen the waste toner tank is full to the level of the waste tonersensor, the senor LED light is blocked by waste toner indicating that the tank is full.

The system initialization process is carried out immediately after power on. The following tasks are performed.1) Initialize ASIC (EPLD)2) Initialize system variables3) Initialize a virtual timer4) Initialize fuser control5) Initialize ADC6) Set-up ITB HOME interrupt

5.2.2 Warm-Up

In the warm-up stage, the following tasks are performed.

1) Self Test* System error check* Cover open check* Device (ITB, OPC, DEVE cartridge) check* Heating error check* Motion of motor and jam & paper empty check* Check Feed and exit sensors. If paper is detected it is ejected. If the paper detection is not

cleared a jam recovery is carried out and the paper drive unit is instructed to drive for the maximum permitted paper length.

2) Heat ControlThe heater control unit separately manages the temperature of the heat lamps.

* Target temperature (165°C)* Temperature below 130°C - heat unit fully on,* Temperature above 135°C temperature is controlled by reading the temperature value

every 10msec.

3) TRC (Toner Reproduction Curve)The TRC process (see page 5-7) is carried out and the developer bias voltage determined.

4) CleaningTransfer rollers, OPC and ITB are electrically and mechanically cleaned.

5.2.5 Print

After sensing the ITB home position the following tasks are performed,Send Psync signal to controller ???Operates virtual timer for each color(Vdata) - Forms latentimage on OPC drum ??Supplies toner on OPC drum - Transfers image to ITB (T1 )- Pickups apaper - Transfers image to a paper (T2)

1)Check ITB Home (Treated by Home interrupt): It is designed to detect ITB HOME every 3 seconds.a) ITB Home sensingb) If a test mode is set up, a test pattern is printed.c) A counter value is set up that addresses the timing to turn on page sync.d) The virtual timer for each color (Y, M, C, and K) is set upe) If Home is not detected every 3 seconds, an error is reported.

2)Paper path and printa) Printing paper from cassette, MPT and SCT is picked upb) Control paper path

* Stop when the leading edge of a piece of paper reaches the feed sensor.* If the leading edge doesn't reach the feed sensor, it is an error.* While transferring the last color to the ITB, re-feed the paper.* Checks if the paper reaches the exit sensor in certain time. If it reaches too soon, or it doesn't

reach, it is an error.* Checks that the paper passes the exit sensor or not.

c) Jam check* Check reaching time and passing time for the paper reaching and passing the feed and exit

sensors. If time exceeds a certain time, it is an error.d) Duplex control

* After passing the exit sensor, the duplex clutch is operated to mechanically change the directionof the paper flow in order to print the other side.

e) Printing sequence and motion for each color* Use a virtual timer for printing the colors in sequence. (Yellow, Magenta, Cyan, Black)

> What is a Virtual Timer?A virtual timer is a mathematical function for creating regular action at fixed time intervals. The stan-dard setting is for a 5msc timer interrupt.

5.2.6 Post-Print

This is the last stage of the printing process. Its functions are described in the below.

a) Clean transfer rollersb) Stop all virtual timerc) It initializes parameter used in printing process.d) Stop motors.

3) Custody of OPC unitIf an OPC unit is exposed with direct sun-light for a long time, its trait can get dam-age, so an exposure on OPC drum cannotbe achieved normally. Therefore, please, be careful with a directsunlight and damage on a drum when dis-assembling.

4) Custody of Toner cartridgeToner cartridge has a fine powder type oftoner, which is injurious to one’s health.Be careful not to leak a toner out of tonercartridge.

5) Disassemble of DEVE drive ass’yand main drive ass’y

It has been set up in factory with using ajig and a driving gear, and it is adjustedfor the best gearing of gear.If a motor is disassembled, a gearingcould be too deeper or too shallow. Itcould cause a noise and image troubles: acolor could spray on a wrong spot orspray unevenly.

6) Disassemble of terminal partsDo not adjust the variable resistors onPBA. It has been already adjusted fromfactory.

7) Disassemble of fuser unit- A fuser melts toner on a paper with its

high temperature: therefore, you needspecial attention not to get an injury byhigh temperature.

When removing a fuser from a set that was aboutto stop operation, you need a special precaution.

- Do not touch an AC line (Copperplate) ofa main frame even after disassembling a fuser.
