First scan sensor—
electrical checks

Turn the power off and reconnect CN10 to the motor driver card. 
Measure the voltages in the table below with the sensor in normal 
operation (sensor closed) and with the sensor open (paper over the 
sensor).

If the voltages are incorrect, replace the first scan sensor. If the 
voltages are correct, go to step 6.

6

ADF scan motor

Check the ADF scan motor for proper operation. Turn the power off, 
disconnect CN3 on the motor driver card, and measure the voltages 
on CN3 on the card.

If the voltages are incorrect, replace the motor driver card. If correct, 
turn the power off, reconnect the motor cable to CN3, and measure 
the voltages on the scan motor connector (see the table above). If 
correct, go to step 7.

7

Scan motor belt

Check the scan motor drive belt for any signs of wear or damage or 
the belt is off the gear. If the belt is off the gear, reinstall. If the belt is 
worn or damaged, replace the belt. If no problem is found, Replace 
the complete ADF assembly. See 

“ADF complete assembly 

removal” on page 4-15

.

Note: Whenever the complete ADF assembly is replaced, is 
necessary to perform the scanner registration. See 

“Scanner 

registration” on page 4-4
