  • Description:Orange light on. The Drum Cartridge has not been mounted.
  • Remedy:1) Check the harness connected between the Engine controller and the drum cartridge. (If the harness is out, insert it to the connector.) 2) In the Engine diagnostic mode, take out the drum cartridge and check for proper operation. (If it doesn t operate, replace the drum cartridge.) 3) After inserting the drum cartridge, check if the Engine controller CN 13 s No. 1 voltage is outputting 5V. (If it is not outputting proper voltage, replace the Engine controller.) 4) Check the existence of the D 12 Open/Short of the Engine controller. (Replace the Engine controller when it is Open/Short.)
  • Code: 02
  • Display:DUPLEX COVER OPEN
  • Description:Orange light on. The duplex cover is open.
  • Remedy:1) Check the harness connection between the SMPS board and the duplex cover sensor. (If the harness is out, insert it to the connector.) 2) In the Engine diagnostic mode, operate the duplex cover open sensor to see if the sensor is operating. (If it is not operating, replace the duplex cover open sensor.) 3) Check if the duplex cover open sensor is showing on/off from the normal operation of the duplex lever swing. (If it is not operating normally, replace the duplex lever swing.) 4) After closing the duplex cover, check to see if the CN307 of the SMPS board is outputting 24V. (If it is not showing appropriate voltage, replace the SMPS.)
  • Code: 03
  • Display:ENGINE FUSER OPEN ERROR
  • Description:Orange light on. When the fusing unit harness is not connecting or thermistor, thermostat is not operating normally.
  • Remedy:1) Check for proper mounting of the fusing unit. (If it is not properly mounted, remount it.) 2) Check for the harness between the SMPS and the fusing unit. (If the harness is out, insert it to the connector.) 3) Check for the harness between the paper size board and the thermistor. (If the harness is out, insert it to the connector.) 4) Check for the harness between the paper size board and the Engine controller. (If the harness is out, insert it to the connector.) 5) Check to see if the thermistor of the fusing unit is normal. (If it is not normal, replace the fusing unit.) 6) Check to see if the thermostat of the fusing unit is normal. (If it is not normal, replace the fusing unit.) 7) Check to see if the lamp of the fusing unit is normal. (If it is not normal, replace the fusing unit.) * Main Lamp (1-6 terminal): About 5.6 * SUB Lamp (3-6 terminal): About 6.8 8) Replace the Engine controller 9) Replace the SMPS.
  • Code: 04
  • Display:ENGINE FUSER LOW HEAT ERROR
  • Description:Orange light on. The fusing unit temperature is lower than the printing temperature.
  • Remedy:1) Check if the fusing unit is mounted properly. (If it is not properly mounted, remount it.) 2) Check for the harness between the SMPS and the fusing unit. (If the harness is out, insert it to the connector.) 3) Check for the harness between the paper size board and the thermistor. (If the harness is out, insert it to the connector.) 4) Check for the harness between the paper size board and the Engine controller. (If the harness is out, insert it to the connector.) 5) Check to see if the thermistor of the fusing unit is normal. (If it is not normal, replace the fusing unit.) 6) Check to see if the thermostat of the fusing unit is normal. (If it is not normal, replace the fusing unit.) 7) Check to see if the lamp of the fusing unit is normal. (If it is not normal, replace the fusing unit.) * Main Lamp (1-6 terminal): About 5.6 * SUB Lamp (3-6 terminal): About 6.8 8) Replace the Engine controller 9) Replace the SMPS.

Code: 05

  • Display:ENGINE FUSER OVER HEAT ERROR
  • Description:Orange light on The fusing unit temperature is higher than the printing temperature.
  • Remedy:1) Check if the fusing unit is mounted properly. (If it is not properly mounted, remount it.) 2) Check for the harness between the SMPS and the fusing unit. (If the harness is out, insert it to the connector.) 3) Check for the harness between the paper size board and the thermistor. (If the harness is out, insert it to the connector.) 4) Check for the harness between the paper size board and the Engine controller. (If the harness is out, insert it to the connector.) 5) Check to see if the thermistor of the fusing unit is normal. (If it is not normal, replace the fusing unit.) 6) Check to see if the thermostat of the fusing unit is normal. (If it is not normal, replace the fusing unit.) 7) Check to see if the lamp of the fusing unit is normal. (If it is not normal, replace the fusing unit.) * Main Lamp (1-6 terminal): About 5.6 * SUB Lamp (3-6 terminal): About 6.8 8) Replace the Engine controller 9) Replace the SMPS.
  • Code: 06
  • Display:ENGINE INTERFACE ERROR
  • Description:Orange light on The communication error between the Engine controller and the Video controller.
  • Remedy:1) Check for the harness connected between the SMPS (CN308) and the Engine controller CN2 sensor. (If the harness is out, insert it to the connector.) 2) Check for the harness connected between the Engine controller (CN5) and the Video controller (CN1) (If the harness is out, insert it to the connector.) 3) Check if the LED in the Engine controller is flashing. (If it doesn t flash, replace the Engine controller.) 4) Replace the Video controller.
  • Code: 07
  • Display:FRONT COVER OPEN
  • Description:Orange light on The front cover is open.
  • Remedy:1) Check for the harness connected between the Engine cover sensor and the front cover sensor. (If the harness is out, insert it to the connector.) 2) In the Engine diagnostic mode, operate the front cover sensor to see if the sensor is operating. (If it doesn t operate, replace the sensor.) 3) Check for any damages or warping to the lever. (If it is warped or damaged, replace the front cover.) 4) In the Engine diagnostic mode, operate the front cover sensor to see if No. 1 voltage of the (Close/open) Engine controller CN8 is changing from 5V to 0V. (If proper voltage is not being outputted, replace the Engine controller.
  • Code: 08
  • Display:FRONT FAN MOTOR LOCK ERROR
  • Description:Orange light on Occurs when the front fan doesn t operate.
  • Remedy:1) Check for the harness between the exit board and the Engine controller. (If the harness is out, insert it to the connector) 2) Check for the harness between the exit board and the front fan. (If the harness is out, insert it to the connector.) 3) Operate the Engine diagnostic mode, operate the front fan to see if the fan is operating. (If it does not operate, replace the front fan) 4) Check to see if the SMPS F3 fuse is disconnected (In the case of disconnection, replace SMPS and check to see if there is a short in the 24V terminal) 5) Replace the exit board. 6) Replace the Engine controller
