Description: Abnormally high fusing temperature
The temperature detected by the Thermistor remains higher than 240 °C for a continuous 50 ms period while fusing temperature control is in progress.
Remedy: 1 Thermistor installed at the correct position. NO Correct. 2 Thermistor contaminated. YES Clean. 3 The circuit across CN1-1 and 2 on the Fusing Unit side is shorted as checked with CN1 disconnected. YES Change Thermistor. NO Change Master Board. Change Power Supply Board.
Code: C0650
Description: Scanner Motor’s failure to turn, Scanner Home Position Sensor malfunction
The Scanner Home Position Sensor is not activated within a given period of time after the Scanner Motor has been energized.
Remedy: 1 Scanner movement after the malfunction has been reset YES To step 4 2 Scanner motion as it is moved manually NO Correct drive coupling. Install belt. 3 Proper JP9 connector connection of Control Board YES Change Scanner Motor. Change Control Board. NO Correct connections. 4 Scanner Home Position Sensor operation: the voltage across JP14-1 on the Control Board and GND is DC0 V (sensor unblocked) and DC3 V (sensor blocked) after the malfunction has been reset. YES Change Control Board. NO Change sensor.
Code: C1200
Description: System memory failure
A memory test error is detected during the power-on initialization procedure.
Remedy: 1. Reset the malfunction. 2. If the malfunction is detected again, check the Control Board and Memory Board for proper connections. 3. If connections are okay, change the Control Board and/or Memory Board.
Code: C1300
Description: Polygon Motor malfunction
• During the period 6 s after the Polygon Motor has been energized, a cluster of 56 or more SOS signals output for a 20 ms period is detected five consecutive times. • After the lapse of 6 s after the Polygon Motor has been energized, a cluster of below 43 or above 56 SOS signals output for a 20 ms period is detected five consecutive times. • No SOS signal is detected during the period from the start of laser emission to the deenergization of the Polygon Motor.
Remedy: 1. Reset the malfunction. 2. If the malfunction is detected again, check the harness between, and PJ connections on, the PH Unit and Master Board. 3. If connections are okay, change the PH Unit and Master Board.
Code: C133B
Description: Option communications error

Remedy: 1. Reset the malfunction. 2. If the malfunction is detected again, check the Control Board and the controller board. 3. If connections are okay, change the Control Board and the controller board.
Code: C13F0
Description: SOS detection failure
• During the period 6 s after the Polygon Motor has been energized, a cluster of 56 or more SOS signals output for a 20 ms period is detected five consecutive times. • After the lapse of 6 s after the Polygon Motor has been energized, a cluster of below 43 or above 56 SOS signals output for a 20 ms period is detected five consecutive times. • No SOS signal is detected during the period from the start of laser emission to the deenergization of the Polygon Motor.
Remedy: 1. Reset the malfunction. 2. If the malfunction is detected again, check the harness between, and PJ connections on, the PH Unit and Master Board. 3. If connections are okay, change the PH Unit and Master Board.
