Before Replacement (Data Backup)
If possible, go through the following procedure:
- Download the data registered in the reader controller RAM by SST.
- Print out the data in the User Mode / Service Mode.
1) After turning ON the power, execute the following service mode:
COPIER > FUNCTION > CLEAR > R-CON
2) If you had downloaded by SST prior to replacement, upload the data.
3) Set the service mode item values as described on the service label.
COPIER > ADJUST > ADJ-XY > ADJ-X (adjustment of image-scanning
start position (leading edge of image) in the direction of the sub-scanner)
COPIER > ADJUST > ADJ-XY > ADJ-Y (adjustment of image-scanning
start position (side-registration) in the direction of the main-scanner)
COPIER > ADJUST > ADJ-XY > ADJ-Y-DF (adjustment of the main
scanner position at ADF stream reading)
COPIER > ADJUST > ADJ-XY > STRD-POS (adjustment of th CCD
reading position at ADF stream reading)
COPIER > ADJUST > ADJ-XY > ADJ-X-MG (fine adjustment of the
sub-scanner reproduction ratio at reading by the pressure plate)
FEEDER > ADJUST > DOCST (adjustment of original stop position at
pickup by ADF)
FEEDER > ADJUST > LA-SPEED (adjustment of original feeding
speed)
FEEDER > ADJUST > STRD-S (adjustment of the optical system stop
position at stream reading mode for small size document)
FEEDER > ADJUST > STRD-L (adjustment of the optical system stop
position at stream reading mode for large size document)
4) Execute the following Service Modes in order.
COPIER > ADJUST > CCD > W-PLT-X
COPIER > ADJUST > CCD > W-PLT-Y
COPIER > ADJUST > CCD > W-PLT-Z
(Enter the white level data for the white plate)
