1

Fuser narrow media sensor

 

Enter the Diagnostics mode, select BASE SENSOR TEST, and

 

(sensor test)

 

select the NM Sensor to test it for proper operation. If the narrow

 

 

 

media sensor fails the test, go to step 2; if the narrow media sensor

 

 

 

does not pass the test, go to step 5.

 

 

 

 

2

Fuser narrow media sensor

 

Check the fuser narrow media sensor cable for correct installation or

 

cable

 

any signs of damage to the cable or to the connectors. If no problem

 

 

 

is found, go to step 3;. If a problem with the installation is found,

 

 

 

install the cable correctly. If damage to the cable or the connectors is

 

 

 

found, replace the cable.

 

 

 

 

 

3

Fuser narrow media sensor

 

Make sure the sensor flag is not binding and is operating properly. If

 

flag

 

the sensor is operating properly, go to step 4. If the sensor is not

 

 

 

operation properly, repair or replace the sensor assembly. See

 

 

 

“Fuser narrow media sensor removal” on page 4-34.

Fuser assembly

 

Check the continuity of the fuser narrow media sensor cable. If

 

Fuser narrow media sensor

 

incorrect, replace the cable; if correct, check the continuity of the

 

 

fuser to system board cable. If incorrect, replace the cable; if correct,

 

cable

 

 

 

replace the following FRUs in the order shown:

 

Fuser board

 

 

 

• Fuser board

 

 

Fuser to system board

 

 

 

 

• Fuser assembly. See “Fuser assembly removal” on page 4-26.

on page 4-76.

 

 

 

 

 

 

 

 

 

5

 

 

With the redrive assembly removed from the printer, enter

 

 

 

Diagnostics mode and run the printer test from tray 1 and observe

 

 

 

the media as it passes over the exit sensor. Check to see that the

 

 

 

sensor flag is operating correctly. If the sensor flag and hardware are

 

 

 

operating incorrectly, repair or replace the failing sensor assembly. If

 

 

 

no problem is found, check the fuser for any signs of media in the

 

 

 

fuser or any signs of toner or other contamination. If a problem is

 

 

 

found, clean or remove the debris or contamination.
