14.3.1 After Replacing the Reader Controller PCB

iR5065 / iR 5055 / iR5075 / / /
Be sure to generate the latest P-PRINT printout before replacing the reader
controller PCB.
- If you are initializing the RAM on the reader controller without replacing
the PCB
Using the SST, upload the backup data of R-CON; initialize the RAM, and
then download the data, thus eliminating the need for the following.
1) Using the SST, download the latest system software (R-CON).
2) Make the following selections in the service mode: COPIER >
FUNCTION > CLEAR > R-CON. Then, press the OK key to execute
RAM initialization. Thereafter, turn off and then back on the main power.
3) Enter the appropriate settings for the following items in the service mode:
a. setting indicated on the service label (found behind the reader unit front
cover)
a-1. image read start position adjustment (X direction; in fixed reading
mode)
COPIER>ADJUST>ADJ-XY>ADJ-X
a-2 image read start position adjustment (Y direction; in fixed reading
mode)
COPIER>ADJUST>ADJ-XY>ADJ-Y
a-3 shading position adjustment (in fixed reading mode)
COPIER>ADJUST>ADJ-XY>ADJ-S
a-4 feeder mode main scanning position adjustment
COPIER>ADJUST>ADJ-XY>ADJ-Y-DF
a-5 ADF stream reading CCD reading position
COPIER>ADJUST>ADJ-XY>STRD-POS
a-6 density manipulating value adjustment
COPIER>ADJUST>CCD>DFCH-G2
COPIER>ADJUST>CCD>DFCH-G10
(After inputs it, execute COPIER>FUNCTION>DF-LNR)
The machine retains ADF-related service data in the RAM of its reader con-
troller.
ADF adjustment is necessary whenever you have replaced the reader con-
troller or initialized the RAM.
b. original stop position adjustment (X direction) (stream reading)
FEEDER>ADJSUT>DOCST
c. original feed speed (magnification) adjustment
FEEDER>ADUST>LA-SPEED
4) Make adjustments using the following service mode items:
a. ADF sensor sensitivity adjustment
FEEDER>FUNCTION>SENS-INT
b. tray width adjustment
FEEDER>FUNCTION>TRY-A4
FEEDER>FUNCTION>TRY-A5R
FEEDER>FUNCTION>TRY-LTR
FEEDER>FUNCTION>TRY-LTRR
c. white plate data adjustment
COPIER>FUNCTION>CCD>CCD-ADJ
d. ADF white level adjustment
COPIER>FUNCTION>CCD>DF-WLVL1
COPIER>FUNCTION>CCD>DF-WLVL2
Be sure to perform white plate data adjustment before performing ADF
white level adjustment.
After having made the foregoing adjustments, put the P-PRINT printout in
the service book case, replacing the previous P-PRINT printout.

14.3.2 When Replacing the CCD Unit

iR5065 / iR 5055 / iR5075 / / /
Perform the following steps after replacing the CCD unit.
1) Enter the correction values to be described on the label included in the
CCD unit (the 2 following items) in the service mode.
- COPIER > ADJUST > CCD > DFCH2G2
- COPIER > ADJUST > CCD > DFCH2G10
2) Transcribe the above correction values to the service label at the back of
the front cover of the host machine.
3) Execute the following in the service mode.
3-1) White plate data adjustment (COPIER > FUNCTION > CCD > CCD-
ADJ)
3-2) ADF white level adjustment (COPIER > FUNCTION > CCD > DF-
WLVL1/2)
Be sure to perform white plate data adjustment before performing ADF
white level plate.

Base
iR5065 / iR 5055 / iR5075 / / /
1) Arrange the mirror positioning tool (FY9-3009-040) so that it is ready for
use in the machine (by changing the pin position; REAR).
2) Arrange the mirror positioning tool so that it is ready for use in the
machine (by changing the pin position; FRONT).
