1.3.20 Checking of CIS Travel and Specifying of CIS Type (Maintenance mode 59)
< Function >
This procedure allows you to check the movement of the CIS unit integrated in the
document scanner unit. The CIS unit travels to the three positions--the white reference
film position, scanning start and end positions.
It also allows you to specify the CIS type into the EEPROM on the main PCB. If you
replace the main PCB ASSY, you need to specify the CIS type according to the
procedure given below.
