Light Adjustment - Canon imageFORMULA DR-M160 Service Manual

2. Light Adjustment

This mode performs fine adjustments on
the shading correction values since the
reading point differs between the white
reference sheet inside of the reading unit
and the actual document.
If the scanned image quality is degraded,
perform this adjustment. Also perform this
adjustment after replacing the reading unit or
after replacing the control PCB recording the
adjustment data.
Adjustment sheet
The shading sheet is required to execute
this mode. Use TKM-0326 or TKM-0332,
which is the same shading sheet as the
one used for the DR-2010C/2510C or
others. Do not use a sheet with any dirt
or creases.
Operation Procedure
