16.6 Electrical Components
16.6.1 After Replacing the Reader
Controller PCB or Initializing the
RAM
-Be sure to generate the latest P-PRINT printout
before replacing the reader controller PCB.
-If you are initializing the RAM of the reader
controller without replacing the PCB, using the SST
to upload the backup data of the reader controller.
Then, after initializing the RAM, download the data
to eliminate the need for the following adjustments:
1. Reader Unit-Related Adjustments
1) Using the SST, download the latest version of the
system software (R-CON).
2) Select the following in service mode, and press the
OK
key
to
COPIER>FUNCTION>CLEAR>R-CON.
Thereafter, turn off and then on the main power.
3) Enter the settings for the following items in
service mode:
(1) standard white plate white level data
COPIER>ADJUST>CCD>W-PLT-X,Y,Z

(h) auto gradation adjustment target value
COPIER>ADJUST>PASCAL>OFST-P-
Y,M,C,K
2. ADF-Related Adjustments
The machine uses the RAM on its reader controller
to store ADF-related service data; as such, you must
make the appropriate adjustments for the ADF
whenever you have replaced the reader controller or
initialized the RAM.
1) Enter the settings indicated on the P-PRINT
printout you have previously generated for the
following items:
(1) original stop position adjustment
FEEDER>ADJSUT>DOCST
(2)
original
feed
adjustment
FEEDER>ADUST>LA-SPEED
2) Make adjustments using the following items:
(1) ADF sensor sensitivity adjustment
FEEDER>FUNCTION>SENS-INT
(2) tray width adjustment
(a) AB system: FEEDER>FUNCTION>TRY-
A4 and FEEDER>FUNCTION>TRY-A5R
(b)
FEEDER>FUNCTION>TRY-LTR
FEEDER>FUNCTION>TRY-LTRR
(3) white level adjustment
