- SYS Transfers the characteristic values of the scanner
(shading correction factor / RGB color correction /
reproduction ratio color deviation correction / shading
position correction factor / reproduction ratio correction
value in primary scanning direction)
- SYS Transfers the characteristic values of the scanner
(shading correction factor / RGB color correction /
reproduction ratio color deviation correction / shading
position correction factor / reproduction ratio correction
value in primary scanning direction) from the SRAM of
the SYS board to the SRAM of the SLG board.
- - Perform the adjustment and initialization when the
RADF board or RADF original reading start sensor is
replaced.
- - Performs adjustment for automatic dust detection with
the shading correction plate. If dust is detected,
shading correction is performed by avoiding the dust.
- - Initializes EEPROM for the RADF.
- - Adjusts the RADF original reading start sensor of the
RADF manually.
SYS Adjusts the detection range for size of original.
<Default value>
NAD/TWD/CND: 128
