290.02 Error code service check
ADF feed jam.
Note: Before starting this service check, make sure the first scan sensor (A) cable is correctly installed.
FRU Action
1 ADF Check for any signs of paper or other debris that might be present in
the ADF assembly over the interval sensor but short of the first scan
sensor. Remove any media found in the ADF, and retry by running
the scanner feed tests. Enter the Diagnostics Menu (turn on MFP
while holding 3 and 6), select SCANNER TESTS, and select Feed
Tests. If the paper fails to reach the first scan sensor, go to step 2.
2
First scan sensor Enter the Diagnostics Menu (turn on MFP while holding 3 and 6),
select SCANNER TESTS, and select Sensor Tests. Check the first
scan sensor for correct operation.
Note: Check the first scan sensor by manually feeding a sheet of
paper through the ADF and checking the sensor for correct
operation.
If the sensor fails the test, go to step 3.
3
First scan sensor cable
(first scan sensor to CN10
on the MDC card)
Check to make sure the interval sensor cable is correctly installed at
the sensor CN10 on the motor drive card. If the cable is not installed
correctly, reinstall the cable. If installed correctly, go to step 4.
4
Motor driver card Turn the power off, and disconnect CN10 on the motor driver card.
Measure the voltages in the table below:
If incorrect, replace the motor driver card. If correct, go to step 5.
A
First scan sensor—reflective type
(normally closed)
Connector CN10 (motor driver card)
CN10—Pin 10 0 V dc
CN10—Pin 11 +5 V dc
CN10—Pin 12 +5 V dc
Note: All voltages are approximate values.
