The configuration of the system used to control the scanner motor is as follows; the motor driver on the interface PCB operates according to the signals from the

CPU to start/stop the scanner motor and to control the direction and speed of its rotation

a. Reverse Movement After a Scan

After an image scan, the No. 1 mirror base is moved in reverse as far as the shading position at 325 mm/sec regardless of the selected magnification.

b. Forward Movement During a Scan

During an image scan, the No. 1 mirror base is controlled at the speed indicated in the following figure; the No. 1 mirror base is moved forward at 325 mm/sec for

100% magnification.

ERROR CODE:

E202 (HP detection error)

-0001: when the No. 1 mirror base is moving forward, it fails to reach the HP sensor within a specific period of time

-0002: when the No. 1 mirror base is moving in reverse, it fails to reach the HP sensor within a specific period of time

SERVICE MODE:

COPIER>ADJUST>ADJ-XY>ADJ-X (scanner image leading edge position adjustment)

Enter a value to adjust the image leading edge position.

settings range: 0 to 2970 (a change of '12' causes a shift of 1 mm)

COPIER>AJST>ADJ-XY>ADJ-S (scanner home position)

Do not change the setting.

5.3.2 Enlargement/Reduction

5.3.2.1 Changing the Reproduction Ratio in Main Scanning Direction

iR7105 / iR7095 / iR7086

To change the magnification in main scanning direction (for both platen and ADF modes), the machine reads the image at 100% and applies appropriate image

processing in the main controller block.
