Remedy: 1. Check power supply to the Power Supply Cooling Fan (FM1) 2.Replace the Power Supply Cooling Fan
Code: E806-0001
Description: Error detection of 3 Way Unit Cooling Fan
When lock of the 3 Way Unit Cooling Fan was detected out for 15 sec
Remedy: The Fan is physically locked or failed, or electrical trouble 1. COPIER > FUNCTION > PART-CHK > FAN; and then move FM04 When the 3 Way Unit Cooling Fan (FM04) works 2-1. Check the harness/connector between the DC Controller PCB (UN09) and the 3 Way Unit Cooling Fan (FM04) 3-1. Replace the 3 Way Unit Cooling Fan (FM04) 4-1. Replace the DC Controller PCB (UN09) When the 3 Way Unit Cooling Fan (FM04) does not work 2-2. Turn the 3 Way Unit Cooling Fan (FM04) with your hand to check for rotation of the fan 3-2. Check the harness/connector between the DC Controller PCB (UN09) and the 3 Way Unit Cooling Fan (FM04) 2. Check conduction of FU11 in the DC Controller PCB (UN09) When the fuse is blown out 5-2-1. Replace the DC Controller PCB (UN09) When the fuse is not blown out 5-2-2. Replace the 3 Way Unit Cooling Fan (FM04) 6-2-2. Replace the DC Controller PCB (UN09)
Code: E807-0001
Description: Error detection of Drum Unit Cooling Fan
Lock of the Drum Unit Cooling Fan was detected out for 15 sec
Remedy: The Fan is physically locked or failed, or electrical trouble 1.COPIER > FUNCTION > PART-CHK > FAN; and then move FM07 When the Drum Unit Cooling Fan (FM07) works 2-1. Check the harness/connector between the DC Controller PCB (UN09) and the Drum Unit Cooling Fan (FM07) 3-1. Replace the Drum Unit Cooling Fan (FM07) 4-1. Replace the DC Controller PCB (UN09) When the Drum Unit Cooling Fan (FM07) does not work 2-2. Turn the Drum Unit Cooling Fan (FM07) with your hand to check for rotation of the fan 3-2. Check the harness/connector between the DC Controller PCB (UN09) and the Drum Unit Cooling Fan (FM07) 4-2. Check conduction of FU9 in the DC Controller PCB (UN09) When the fuse is blown out 5-2-1. Replace the DC Controller PCB (UN09) When the fuse is not blown out 5-2-2. Replace the Drum Unit Cooling Fan (FM07) 6-2-2. Replace the DC Controller PCB (UN09)
Code: E808-0001
Description: Zero cross signal detection error
Unable to detect 43 to 57Hz for 5000 msec or longer at the start of zero cross detection
Remedy: Electrical trouble with failed zero cross signal 1. Check failure between the AC Driver PCB (UN14/ J122) and the DC Controller PCB (UN09/ J10). (trapped cable, open circuit, connector disconnection) -> Replace the part in the case of trapped cable/open circuit 2. Replace the AC Driver PCB (UN14) 3. Replace the DC Controller PCB (UN09) 4. Check the power supply condition at the customer site. When it is below 43 to 57Hz, ask for a construction work.
Code: E808-0002
Description: Zero cross signal detection error
Unable to detect 43 to 57Hz for 500 msec or longer after confirmation of a zero cross cycle
Remedy: Electrical trouble with failed zero cross signal 1. Check failure between the AC Driver PCB (UN14/ J122) and the DC Controller PCB (UN09/ J10). (trapped cable, open circuit, connector disconnection) -> Replace the part in the case of trapped cable/open circuit 2. Replace the AC Driver PCB (UN14) 3. Replace the DC Controller PCB (UN09) 4. Check the power supply condition at the customer site. When it is below 43 to 57Hz, ask for a construction work.
Code: E880-0001
Description: Controller Fan error
Lock of Controller Fan is detected
Remedy: Check if the connector is connected If the connector is OK, replace Controller Fan (FM3)
