GAIN-EG Gain level of Img Sensor even bit(G):frt
Lv.2 Details To display the Green gain level adjustment value in even-numbered
bit on CMOS Sensor of Scanner Unit (paper front).
Continuous display of upper limit is considered a failure of the
Scanner Unit/Reader Controller PCB.
When the value is out of the target value range, image failure
or E302 (shading error) may have occurred. Identify the cause
according to the value.
Use case - When replacing the Reader Controller PCB
- At scanned image failure
Display/adj/set range 0 to 143
Appropriate target value 0 to 143
GAIN-ER Gain level of Img Sensor even bit(R):frt
Lv.2 Details To display the Red gain level adjustment value in even-numbered bit
on CMOS Sensor of Scanner Unit (paper front).
Continuous display of upper limit is considered a failure of the
Scanner Unit/Reader Controller PCB.
When the value is out of the target value range, image failure
or E302 (shading error) may have occurred. Identify the cause
according to the value.
Use case - When replacing the Reader Controller PCB
- At scanned image failure
Display/adj/set range 0 to 143
Appropriate target value 0 to 143
