5. Light Adjustment
This mode performs fine adjustments on
the shading correction values since the
reading point differs between the white ref-
erence 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.
This mode can be used together with
other adjustment items. For details, refer to
[All Adjustment].
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 P-150 or others. Do not
use a sheet with any dirt or creases.
Note:
Shading sheets with a black line for
"Registration Adjustment[Auto]" can
also be used.
Operation Procedure
1) Clean feed path, roller, and reading glass.
