Action

 

 

 

 

1

 

System Board

Turn the printer on and verify the paper feed motor activates. Be sure

 

 

 

the end-of-form sensor lever is in the down position. Turn the printer off

 

 

 

and disconnect CN1 from the system board. Check for motor pins

 

 

 

shorted to the motor housing. If you find a shorted pin,replace the

 

 

 

paper feed motor. If you still have a failure after replacing the paper

 

 

 

feed motor,replace the system board.

Paper Feed Motor

A noisy or chattering motor or a motor that fails to turn,can be caused

 

 

 

by an open or short in the motor,an open or short in the motor driver on

 

 

 

the system board,or a bind in the paper feed mechanism. With the

 

 

 

paper feed motor cable CN1 disconnected from the system board,

 

 

 

check for 140 ohms(±7%)between the follwing pins on the motor

 

 

 

: Pin 1 to Pin 2,Pin 1 to Pin 4

 

 

 

280 ohms(±7%)between pins 2 and 4. If the readings are

 

 

 

incorrect,replace the paper feed motor and drive train assembly.

 

 

 

Although the paper feeds in a forward direction only,the paper feed

 

 

 

motor turns in two directions.

 

 

 

If the paper feed motor turns in one direction only,replace the system

 

 

 

board.

 

 

 

Binds in the paper feed motor or gear train can cause intermittent false

 

 

 

paper jam errors. Remove the paper feed motor and check the shaft

 

 

 

for bins.

 

 

 

Also check for loose or worn motor gear.

Drive Train Assembly

Check for binds in the gear train and paper feed machanism by remov-

 

 

 

ing the paper feed motor and rotating the large gear by hand . If you

 

 

 

notice a bind,replace the drive train assembly. Check the feed clutch

 

 

 

gear on the left side of the auto sheet feeder. Turn the clutch gear and

 

 

 

check that it rotates freely in one direction and locks when turned in the

 

 

 

opposite direction.
