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

 

 

• A bind in the paper feed mechanism

 

 

With the paper feed motor cable disconnected

 

 

from the system board, check for 5 to 10 ohms

 

 

between pin 1 and 4 on the motor cable.

 

 

If the reading is incorrect, replace the motor.

 

 

Check for motor pins shorted to the motor housing.

 

 

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

 

 

failure remains, replace the system board.

 

 

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 binds.

 

 

Also check for loose or worn motor gear.

Gears

Check for binds in the gear train and paper feed

 

 

mechanism by rotating the large feed roll by hand.

 

 

If you notice a bind, isolate it by removing one of

 

 

the small idler gears on the inside of the left side

 

 

frame. Replace any worn or binding gears or

 

 

rollers.

 

 

 

4

Feed Arm

At the beginning of the paper feed operation, the

 

Assembly

paper feed motor reverses momentarily to allow

 

 

the feed arm pawl to drop off the home position

 

 

notch in the left side frame. If the pawl fails to drop

 

 

off the notch, check the feed arm assembly for

 

 

binds, and worn or broken parts.
