Step Check points Solutions
1 Is the actuator of the document sensor dam-
aged?
Replace the operation panel.
2 Select SENSOR TEST in the test mode. (Refer
to P.11-19 "[ 5 ] SENSOR TEST [MENU], [9],
[4], [05]".)
Open the operation panel.
When the document sensor is turned ON, is the
Bit 4 changed?
When the bit changes correctly, go to step 4.
3 Is the cable firmly connected between the opera-
tion panel and the main PBA (CN4)?
Insert the cable to the connector firmly.
4 Is the cable of the TX motor firmly connected to
the main PBA (CN6)?
Insert the cable to the connector firmly.
5 Does the connector pin come off or is the cable
broken?
Replace the cable.
6 Open the operation panel. Turn ON the docu-
ment sensor to see if the ADF roller and TX drive
roller operate properly.
Check the gear of each roller and the gear of the
TX motor gear assembly. Replace those which are
damaged.
7 If no problem is found in the steps above, the TX
motor or main PBA may be defective.
Replace the TX motor and then the main PBA.
Step Check points Solutions
1 Were the documents pressed into the ADF too
strongly when loaded?
Load documents correctly.
2 Are the document sheets curled? Use appropriate paper for documents.
3 Are the document sheets hard to separate due to
static electricity?
Use appropriate paper for documents.

specifications (60 to 105 g/m
2
)?
Use appropriate paper for documents.

tions.

cloth with water and squeeze it well, then use it for
wiping the dirt off.
If worn out, replace the part.
