• Drive Unit 1

Drive 2 Stepper

If the motor does not attempt to turn and you receive

a 910 error code, replace the driver 1 dc motor.

Be sure the toner and photodeveloper units are not

causing an overload on the dc motor.

If the motor turns but the paper carrying section of

the machine does not rotate, check the drive 1 unit

gear train for damage. Be sure the clutch on the

gear train engages for color printing. Replace the

drive 1 unit if necessary.

If this does not correct the problem, replace the

printer controller board.

Be sure connector CN4 on the printer controller

board is firmly connected. If there still is a problem,

replace the drive 2 stepper motor.
