I believe you may have a power voltage supply to the Reader/
check your 24v dc supply on Reader pcb.
J500-supplies power to the ADF.
J501 -receives power from the machine body (printer unit).
J502 -communication with the machine body (printer unit).
J503 -communication with the ADF.
J504 -communication with the ADF.
J505 -connects to the main motor.
J506 -copyboard cover open/closed sensor; connects to the CIS HP sensor
J507 -connects to original sensor 1, original sensor 2.
J508 -connects to original sensor 3, original sensor 4.
J510 -connects to the contact image sensor (CIS).
J512 -for use at factory
J513 -for use at factory

check the interface power cable from reader to printer/ remove the cover off the cable & check interior connectors

Thank you Mr teckat for your info.
I follow the instruction and the 24v was find.
Try to change another piece of reader controller and the error code was gone.
Is my mistake to change the spoilt pcb.

After Replacing the Reader Controller PCB
or
After Initializing the RAM

COPIER>FUNCTION>CLEAR>R-CON
then,press the OK key to initialize the RAM. Thereafter,
turn off and then on the main power.
Enter the appropriate values using the following service mode items:service label (behind reader unit left cover)values.

a-1. CIS read position adjustment (fixed reading)
COPIER>ADJUST>ADJ-XY>ADJ-X
a-2. main scanning direction position adjustment
(fixed reading)
COPIER>ADJUST>ADJ-XY>ADJ-Y
a-3. shading position adjustment (fixed reading)
COPIER>ADJUST>ADJ-XY>ADJ-S
a-4. main/sub scanning direction MTF value
COPIER>ADJUST>CCD>MTF-MG
If the value of the following was not 0 before the
replacement of the reader controller PCB:
COPIER>OPTION>BODY>CCD-LUT.
Set a value other than '0' once again, and make the following adjustments using the D-10 Chart.
COPIER>FUNCTION>CCD>LUT-ADJ2

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>STRDPOS
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 printout [1] you have previously generated in the service book cassette to replace the old P-PRINT printout.
