59.00.YY Error To continue turn off then on
Description
The product experienced a printing error.
Recommended action
59.00.04 or 59.00.05: Fuser motor (M2) start up error or fuser motor (M2) rotational error—
pressure roller, delivery roller, fuser pressurization, primary transfer roller disengagement
1. Use the fuser motor (M2) drive test in the component test to verify that the fuser motor is properly
functioning. If it is not, replace the fuser motor assembly.
2. If the product was previously serviced, check the connector (J15) on the fuser motor and the
connector (J17) on the DC controller PCA.
59.00.90 or 59.00.A0: ITB motor (M1) start up error or ITB motor (M1) abnormal rotational
error
1. Remove the ITB and check for damage.
2. Use the ITB motor (M1) drive test in the component test to verify that the ITB motor is properly
functioning. If it is not, replace the ITB motor assembly.
3. If the product was previously serviced, check the connectors at the ITB motor assembly and the DC
controller. See the circuit diagram for details.
59.00.C0: Developer alienation motor (M10) error
1. Use the developer engagement and disengagement drive test in the component test to verify that
the disengagement mechanisms are properly functioning. If they are not, replace the developer
alienation motor.
2. Use the Manual Sensor Test to verify that the developer disengagement sensor (SR11) is properly
functioning. The sensor is located inside the main drive assembly and cannot be reached for
testing. Disconnect the connector (J112) at the DC controller while in Manual Sensor Test mode to
verify the sensor operation. If it is not operating, replace the main drive assembly.
3. If the product was previously serviced, check the intermediate connector (J87) of the developing
disengagement sensor, the connector (J112) on the DC controller PCA, the connector (J38) of the
developing disengagement motor, and the connector (J261) on the high-voltage power supply D
PCA.
59.00.F0: T1 alienation mechanism failure
1. Make sure that the ITB is correctly installed.
2. Use the T1 roller alienation sensor (SR9) test in the Manual Sensor Test to verify that the sensor is
properly functioning. If it is not, replace the sensor assembly.
3. Use the T1 roller engagement and disengagement drive test in the component test to verify that the
T1 roller disengagement mechanism is properly functioning. If it is not, remove the ITB and
