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

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.
5.3.2.2 Changing the Reproduction Ratio in Sub Scanning Direction <iR7105/7095>
To execute scaling, the moving speed of the mirror 1 mount is changed.
Also, digital scaling is concurrently used under the following conditions:
- Fixed reading: scaling is from 25 to 99.9%
- Stream reading: scaling is from 25 to 88.9%
MEMO:
Stream reading is basically executed when a copy is made with the ADF. However,
fixed reading is executed instead if scaling is from 25 to 49.9% or a 2-sided copy is made at any scaling
factor. Fixed reading is executed whenever a copy is made in book mode.
5.3.2.3 Changing the Reproduction Ratio in Sub Scanning Direction <iR7086>
To execute scaling, the moving speed of the mirror 1 mount is changed.
Also, digital scaling is concurrently used under the following conditions:
- Fixed reading: scaling is from 25 to 99.9%
- Stream reading: scaling is from 25 to 50%
