Action

 

 

 

1

Engine Board Jumpers

Check to make sure a jumper is

 

 

installed between JP1-1 and JP1-2

 

 

and also between JP2-1 and JP2-2 on

 

 

the engine board.

Fuser Envelope Conditioner

The operation of the fuser solenoid

 

Solenoid Fuser Control

can be observed by removing the

 

Board

redrive assembly. Check for proper

 

 

mechanical operation of the solenoid

 

 

and associated hardware, link and so

 

 

on. If correct, disconnect the DC fuser

 

 

cable from J1 on the fuser control

 

 

board and check the resistance of the

 

 

solenoid between J1-2 and J1-4 on

 

 

connector J1. The resistance

 

 

measures between 5 ohms and 10

 

 

ohms. If incorrect, disconnect the

 

 

solenoid from J4 and check the

 

 

resistance of the solenoid between

 

 

J4-1 and J4-2. If incorrect, replace the

 

 

solenoid assembly. If correct, replace

 

 

the fuser control board.

 

 

 

3

Fuser Cable

Check the continuity of the fuser

 

 

cable. If the cable does not measure

 

 

continuity, replace the cable.
