The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with reference to the timing of operation.
In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol, the arrow indicates the direction of the electric signal. The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results in supplying the machine with power.
2. In the digital circuits, '1' is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low". (The voltage value, however, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'.
In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations of the microprocessors used in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of the DC controller PCB to the loads.
The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be communicated in the form of Service Information bulletins.All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and be able to identify and isolate faults in the machine.

White plate dust detection controlIn this machine, the fans cool down the inside of the DADF to prevent the overheating at stream reading operation. As a result, dust in the DADF may stick to the white plate and it may cause the lines on the image.To reduce the influence from the dust, the white plate dust detection and correction are performed.
(1) White plate dust detectionThe machine compares the shading coefficient obtained from shift shading and the shading coefficient obtained from fixed shading to identify the presence/absence of dust and, if any, identifies the coordinates and width of the area.
(2) White plate dust correctionIf the machine detects the dust as a result of white plate dust detection, it interpolates the shading coefficient of the area using the shading coefficient of both sides so as to decrease the effects of the presence of dust. It executes the shading correction using the shading coefficient obtained after the interpolation.When the dust is detected as a result of white plate dust detection, the machine interpolates the shading coefficient of the dust area using the shading coefficient of both sides so as to reduce the effects of the dust. The shading correction is executed after the interpolation.

Scanning glass dust detection controlIn the case of 2-side scanning with this equipment, dust and smudges on the scanning glass (attached when scanning the back side) can cause lines on the image.To prevent this symptom, there is a dust detection correcting function with this equipment.This function makes the reader controller to shift the scanning glass to the scanning position at detection timing for detecting the degree of smudges on scanning surface.In the case of smudges detected at the scanning position, the scanner unit is shifted to smudge-free position to prevent image fault.There are 3 scanning positions to be detected in the order as shown below. If there is smudge at the first position, the scanning position is shifted to the next scanning position to execute scanning of the backside.If smudge is detected at all 3 scanning positions, a user message is displayed to encourage cleaning of the scanning glass (DF operation is available when this message is shown).

Dust detection correction control (noncontinuous lines)This control detects and corrects lines caused by dust that failed to be detected between sheets.Dust attached to the original is not detected at the lead edge of the original.This dust can be attached to the original again after being remained at the scanning position due to friction with the scanning glass while this dust passes through the scanning position. In this case, this dust will not be detected even at the trail edge because the dust is fed together with the original.The lines (created as described above), occurring noncontinulusly from the lead edge to the trail edge of the original, are detected for image correction.
Correction is performed symmetrically for lines stretching in sub (vertical) scanning direction on scanned image. Identifying lines (caused by dust) with length, color and brightness of lines, correction is performed for such lines determined as lines caused by dust

If there are ultrafine lines on the original while this item is set ON, they are wrongly detected as noncontinuous lines, and those ultrafine lines can be removed from the scanning image. Select OFF for this item if there is frequent removing of lines due to wrong detection for ultrafine lines on the original.

■ Detection at Start of Pickup
Detection in feed directionThe size of original is determined whether it is LTR-R or LGL by LTR-R/LGL identification sensor (SR8).Once an original is placed on the original pickup tray, the light-blocking plate operates in keeping with the detection lever of LTR-R/LGL identification sensor (SR8) and blocks the light of photo interrupter.With reference to the signal (LGL_S) of the LTR-R/LGL identification sensor (SR8) and the original width, the machine determines whether or not the paper on the original pickup tray is LGL.The machine communicates the original size information with the connected devices as soon as the start key is turned ON.

Detection of width directionThe size of original in width direction is detected by the original width volume (VR) and the AB/ Inch identification sensor (SR7) on the original pickup tray.The original width volume (VR) operates together with the slide guide and its resistance value is changed to analog as the slide guide is moved. The DADF driver PCB (PCB1) reads these changes in resistance as the original size signal (VR) and converts it into the size in width direction.
The AB/ Inch identification sensor (SR7) is installed inside the original pickup tray to perform the width detection between A4 and LTRR, or between A5R and STMTR correctly on the original width volume (VR). The AB/ Inch identification sensor (SR7) outputs AB/ Inch detection signal (A4LT_S) “1” when the original width is “127 mm or longer and shorter than 148 mm” or “197 mm or longer and shorter than 214 mm”.

● The stop position of the slide guide can be changed by changing (turning around) the attaching of the positioning roll [1] of the slide guide as shown below.There is a groove on the rail of the slide guide so that the slide can stop at specific default sizes. Some sizes, however, are extremely close to each other, possibly causing the slide to stop at the wrong position. To make sure that the slide is at the correct position, the stop position is adjusted with the positioning roll [1].

Original Detection ControlThe original sensor (SR1) identifies whether the original is present or not on the original pickup tray.Once an original is placed on the original pickup tray, the detecting lever operates together with the light blocking plate and the light blocking plate passes through the photo interrupter. As a result, the original sensor (SR1) generates the original detection signal (EMP_S).Once the tray open/closed sensor (SR9) and the cover open/closed sensor (SR10) detects that the original pickup tray and the feeder cover are closed respectively, they generate the original pickup tray open detection signal (TRAY_OPEN_S) and the feeder cover open signal (COVER_S).Once the DADF driver PCB receives the original pickup tray open signal (TRAY_OPEN_S), feeder cover open signal (COVER_S) and original detection signal (EMP_S), the original set display activation signal (EMP_LED) is generated to activate the original set display (LED).

4) Tray lifter motor (M8) starts driving and the tray lifter arm pushes the original pickup tray (upper) upward.
5) The pickup roller unit is pushed up until the original contacts the pickup roller unit and the paper surface sensor (SR6) detects it.
6) The tray lifter motor (M8) stops driving once the paper surface sensor (SR6) detects the pickup roller unit.
7) The machine executes pickup (after the start key is pressed)(see MEMO).8) If the paper surface sensor (SR6) cannot detect the pickup roller unit during pickup, the tray
lifter motor (M8) starts driving and the original pickup tray is again moved up until the paper surface sensor (SR6) detects the pickup roller unit.

b. Pickup completion1) When the original sensor (SR1) cannot detect an original, the tray lifter motor (M8) drives
the tray lifter arm (opposite direction to at the time of pickup) to move down the original pickup tray.
2) Once the tray home position sensor (SR13) detects that the tray lifter arm is shifted down to the lowest position, the pickup roller unit lifter motor (M10) starts driving to rotate the cam downward.
3) Downward shifting of cam makes the pickup roller unit return to the pre-pickup position and pickup operation completes.

MEMO : Additional functions (Timing to Raise Feeder Tray)To reduce the time from when the start key is pressed until pickup is stared, the timing for moving up the original pickup tray can be specified in additional function mode.Setting is available as follows.
When Start is pressed: the original pickup tray starts moving up when a start key is being pressed. (default)From Panel: the original pickup tray starts moving up when any key or button is navigated on a control panel after an original has been placed.
The lifter drive of the original pickup tray enables the stacking of 300 sheets (80 g/m2) and stream scanning; however, it takes time for the original pickup tray to be moved up to the pickup position in the case of scanning of small number of originals (such as 1 sheet of original).Time for pre-pickup operation after pressing the start key can be reduced by making the original pickup tray start moving up upon navigating the control panel.

MEMO: Additional functions (Feeder Jam Recovery Method)Recovery method can be specified in the case of jam in stream scanning mode of original.Setting method is available as below.
From 1st Page: Reset all of originals to the original pickup tray after jam recovery. Once the start key is pressed, the scanned originals up to the jam occurrence are fed idly and the rest of the originals are to be scanned (default).From Stop. Original: Reset just the rest of originals which haven’t been scanned to the original pickup tray. Once the start key is pressed, the rest of the originals are to be scanned.
This equipment can perform the stream scanning with up to 300 sheets (80 g/m2). However, for example, if a jam occurred at the 299th sheet while executing stream scanning of 300 sheets of original, and starting from the 1st original sheet, it takes 2 min or more for idle-feeding. Then jam recovery time can be reduced by resuming from the rest of the originals.
