Front Harness Cable

Check the toner sensor portion of

 

 

the front harness cable to make sure

 

 

it is properly seated into the toner

 

 

sensor. If correct at both the sensor

continuity of the cable. If incorrect,

 

 

replace the cable.

Toner Sensor

The toner sensor cable is part of the

 

 

front harness and part of connector

 

 

J10 on the engine board. Check the

 

 

voltage at J1-011. It reads

 

 

approximately +5 V dc. If incorrect,

 

 

replace the engine board. If correct,

 

 

check the voltage at J10-12. It reads

 

 

approximately +5 V dc with the

 

 

controller board removed from the

 

 

printer. If incorrect, replace the

 

 

engine board. If correct, replace the

 

 

toner sensor assembly. A bad

 

 

ground connection between J10-13

 

 

on the engine board and pin 3 on the

 

 

toner sensor results in a 929 service

 

 

error.
