Troubleshooting with the copy processor board

 

The table in this section is a quick reference source for troubleshooting common copy processor

 

board (CPB) failures that might occur after or during CPB initialization. The LED pattern column

 

describes the status of the four LEDs located on the back of the MFP. The control-panel display

 

column lists the messages that appear on the control-panel display when a failure occurs. The

 

MFP functionality column describes what MFP functions are affected by the CPB failure. The

 

action column lists the appropriate CPB troubleshooting steps.

 

To troubleshoot the CPB using the LEDs, check the LEDs that are illuminated and those that are

 

not. Check for messages appearing on the control-panel display. Press the SELECT ( ) button to

 

select OK. Match the LED pattern to the examples found in table 19 on page 125. Perform the

 

corresponding procedure that is listed in the action column of the table.

 

For information about LED patterns that appear while the CPB is initializing, see “Copy

 

processor board LEDs” on page 59.

 

 

Note

This section does not describe copy processor board LED patterns that occur during CPB

 

initialization (when MFP power is first turned on). For information about CPB initialization LED

 

patterns and their meanings, see “Copy processor board” on page 57.

 

The print and scan units have separate power supplies. The control panel and the CPB are

 

powered by the power supply in the scan unit.

 

 

 

 

Hint

The LEDs can be difficult to see through the holes provided in the CPB faceplate (callout 1) in a

 

high-light environment. It might be necessary to turn off some lights or remove the faceplate to

 

see the LEDs.
