CHAPTER 1 GENERAL DESCRIPTION
3.2 Outline of the Electrical Circuitry
3.2.1 Construction of the Electrical Circuit
The major electrical mechanisms of the machine are controlled by the following PCBs:
[1]Man controller PCB; controls the system as a whole, processes images
[2]DC controller PCB; controls the printer unit, controls the finisher communication
[3]Reader controller PCB; controls the reader unit, controls the DADF communication

CHAPTER 2 ORIGINAL EXPOSURE SYSTEM
1. Outline of Operations
1.1 Outline
The original exposure system has the following major functions:
Item |
Description |
|
Original illumination |
Xenon tube |
|
Original scanning |
In Book mode: by moving scanner |
|
|
With ADF in use: by fixed No. 1 mirror base at stream reading po- |
|
|
sition |
|
scanner position detection |
Scanner HP sensor (PS400) |
|
Reproduction ratio (zoom) |
[1] Copyboard Mode (25% to 800%) |
|
|
Main scanning direction: image processing by controller assembly |
|
|
Sub scanning direction: |
for a ratio of 50% or higher, changing |
|
|
scanning speed of No. 1 mirror; for a |
|
|
ratio of lower than 50% and 400% or |
|
|
higher, chaining scanning speed and im- |
|
|
age processing |
|
[2] ADF Mode (25% to 400%) |
|
|
Main scanning direction: image processing by controller assembly |
|
|
Sub scanning direction: |
for a ratio of 50% or higher, changing |
|
|
original feeding speed; for a ratio of |
|
|
lower than 50% and 200% or higher, |
Scanner drive control |
No. 1/No. 2 mirror base: control by stepping motor (M400) |
|
Lens |
Lens array, fixed type |
|
Scanning lamp control |
[1] Control of activation by inverter circuit |
|
|
[2] Control for error detection |
|
Original size detection |
[1] In Book Mode |
|
|
Sub scanning direction: by reflection type sensor |
|
|

CHAPTER 2 ORIGINAL EXPOSURE SYSTEM
1.2 Changing the Reproduction Ratio (Zoom)
[1]In Copyboard Mode
If for a reproduction ratio of 25% to 800%, the speed of the scanner is changed.
[2]With ADF in Use
If for a reproduction ratio of 25% to 400%, the speed of the movement of the original is changed.
1.2.1 Changing the Reproduction Ratio in Main Scanning Direction
For scanning direction, reading is always at 100% in both copyboard and ADF modes; the ratio is changed in the course of data processing in the main controller assembly.
To reduce, data units are skipped. To enlarge, data units are repeated.
1.2.2 Changing the Reproduction Ratio in Sub Scanning Direction
For sub scanning direction, the speed of the scanner/movement of the original is changed. However, for a reduction between 25% and 49% and enlargement between 401% and 800%, data processing in the main controller assembly is also used in combination.
[1]For enlargement, the speed of the mirror/original is reduced from that used in Direct: e.g., at 200%, the speed is 1/2 of the speed used in Direct.
[2]For reduction between 50% and 99%, the speed of the mirror/original is increased; e.g., at 50%, the speed is twice as high as that used in Direct.

1.1 Outline
Part 2>Chapter 4>1.1 “Outline of Laser Exposure”
The reader controller PCB serves to read image signals from the CCD and send image signals to the main controller assembly. The video signals from the main controller assembly are converted by the DC controller PCB into laser drive signals, and are turned into laser intensity signals to suit signal levels by the laser driver PCB.
The laser intensity signals are used to cause the laser unit to generate a laser beam, which is directed to the photosensitive drum for the formation of latent static images.
The laser beam is also used for blank exposure to create non-image areas.

2 Generating Sync Signals
2.1 Outline
Part 2>Chapter 4>2 “Generating BD Signals”
The BD signal used to synchronize the video signals in laser scanning direction is generated by the BD PCB with reference to the laser beam reflected by the BD mirror mounted in the path of the laser beam.
The edge of paper re-picked in double-sided mode is detected by the horizontal registration sensor to measure the displacement to the rear/front. Based on the measurement, the timing of laser activation is changed with reference to the BD signal so that the image will be placed at a specific position on the paper without fail.

2.2 Flow of Sync signals
[1]The BD signal goes ‘0’ when laser light is detected.
[2]The phase is matched with the phase of the printer, and a sync signal is generated.
[3]Based on the printer sync signal, image data is read from the image memory.
[4]Video signal
[5]The 2-pixel parallel signal is converted into a single-pixel serial signal.
[6]The laser drive signal is used to drive the laser unit to suit the video signal.

CHAPTER 3 LASER EXPOSURE SYSTEM
3 Laser Driver Circuit
3.1 Controlling the Laser Unit
The laser driver circuit is used to drive the semiconductor laser according to the laser drive signal from the DC controller PCB.
The laser driver circuit performs the following:
1.Turning on/off the laser.
2.Controlling the light intensity of the laser (APC control).
The signals have the following meanings and functions:
[1]Laser drive signal; used to drive the semiconductor laser.
[2]Sample laser activation signal; used to turn on the laser for intensity sampling (the result is used for activation for imaging).
[3]Laser enable signal; goes ‘0’ when the laser is ready after the Start key is pressed.
[4]Image leading edge signal; used to start laser writing when paper reaches the image leading edge sensor (PSS12) mounted in front of the photosensitive drum.
[5]Used to monitor the laser intensity when the laser is turned on for sampling, and feeds back the level appropriate to the intensity to the laser driver circuit.
[6]Used to control the output so that the feedback level and the reference level from the DC controller will be identical.
[7]Laser intensity reference signal; used as the laser activation reference level determined by the DC controller.
[8]Horizontal registration paper detection signal; used to adjust the image position by changing the timing of laser activation with reference to the result of detection of the edge of paper re-picked in double-sided mode by the horizontal registration sensor (PS11).
