2. ADF-Related Adjustment
The machine keeps ADF-related service mode data in the RAM of the
reader controller; as such, you will have to make the appropriate
adjustments if you have replaced the reader controller or initialized the
RAM.
1) Enter the values indicated in the P-PRINT printout you have previously
generated for the following:
a. main scanning direction position adjustment (stream reading)
COPIER>ADJSUT>ADJ-XY>ADJ-Y-DF
b. original stop position adjustment
FEEDER>ADJSUT>DOCST
c. original feed speed (magnification) adjustment
FEEDER>ADUST>LA-SPEED
2) Make adjustments using the following items:
a. tray width adjustment
FEEDER>FUNCTION>TRY-A4
FEEDER>FUNCTION>TRY-A5R
FEEDER>FUNCTION>TRY-LTR
FEEDER>FUNCTION>TRY-LTRR
b. CIS read position adjustment (stream reading)
COPIER>FUNCTION>INSTALL>STRD-POS
c. white level adjustment
COPIER>FUNCTION>CCD>DF-WLVL1
COPIER>FUNCTION>CCD>DF-WLVL2
When you have finished the foregoing adjustments, put the P-PRINT print-
out [1] you have previously generated in the service book cassette to replace
the old P-PRINT printout.

0014-3128
/ / / / iR C3380i / iR C3380 / iR C2880i / iR C2880
Upon replacement to the new secondary transfer outer roller, attachment of
the rubber component of the secondary transfer roller onto the ITB belt caus-
es a white spot image.
In order to prevent this, at replacing the secondary transfer outer roller to the
new one, coating of toner onto the surface of the roller is required.
When replacing the secondary transfer outer roller, execute the service mode
below:
- COPIER > FUNCTION > TNR-COAT
Coating of the Y toner onto the secondary transfer roller
In case the white spot image occurred after replacing the secondary transfer
roller, clean the ITB unit.
Initial settings / registration > adjustment / cleaning > cleaning within the
main body
