• Code: E012-2000
• Description: Rotation error of Drum Motor (Y/M/C/Bk) (M21/23/25/19) and ITB Drive Motor. Simultaneous rotation error in all Motors
• Remedy: 1. Check the connection of the Drum ITB Driver PCB. PCB side: J1902 to J1904 2. Check the connection of the Relay PCB. PCB side: J1805 3. Check the Interlock Switch. 4. Check if the Harness of the Drum ITB Driver PCB (UN6) is faulty.

• Code: E012-3000
• Description: Error in Drum Speed Detection PCB (UN18 to 25) of all colors. This error occurs when the Drum Speed Detection PCB (UN18 to 25) error is detected for all colors simultaneously
• Remedy: 1. Check the connection of the Drum ITB Driver PCB. PCB side: J1902, J1904, J1905 2. Check if the Harness of the Drum ITB Driver PCB (UN6) is faulty. 3. Replace the Drum ITB Driver PCB.

• Code: E012-3001
• Description: Control error of Drum Motor (Y/M/C/Bk) (M21/23/25/19). This error occurs when the Drum Motor (Y/M/C/Bk) (M21/23/25/19) control error is detected for all colors simultaneously.
• Remedy: 1. Check the Process Unit (to see if the Connector is physically removed). 2. Check the Drum Unit (to see if the Connector is physically removed).

• Code: E012-3002
• Description: Rotation error of Drum Motor (Y/M/C/Bk) (M21/23/25/19). All of the Drum Motors (Y/M/C/Bk) (M21/23/25/19) are not rotating at the specified speed, or they are stopped.
• Remedy: Check the connector of the Drum ITB Driver PCB (UN6). PCB side: J1902 to J1904

• Code: E013-0001
• Description: Waste toner feed screw lock detection error. When the waste toner pipe screw lock SW (SW10) detected the lock status for 500 msec (100 msec x 5 times) consecutively
• Remedy: • Pull out the Waste Toner Container. If it is full of toner, go to Step 1, 2, and 5. • If the Waste Toner Container is not full of toner, go to Step 1, 2, and 4. • If the Waste Toner Container is not full and the Waste Toner Pipe is not clogged with toner, go to Step 3 and 4. 1. Remove the toner in the Waste Toner Pipe. 2. Replace the Waste Toner Full Sensor and the Waste Toner Container. 3. Replace the Waste Toner Screw Lock Detection Switch (SW10). 4. Replace the Waste Toner Drive Unit. 5. Reduce the value of timing setting for waste toner full alert display (COPIER> ADJUST> MISC> WT-FL-LM) by 1.

• Code: E013-0003
• Description: Waste toner full sensor error. Output of the waste toner full sensor cannot be detected.
• Remedy: Supply when an error is detected, it is needed to restart and check the power output before the machine detects the error to determine whether the cause of the error is power supply. If there is no power output, power supply is the cause. If there is power output, factor other than power supply can be the cause of the error. 1. Check the connection between the Waste Toner Full Sensor (TS9) and thePickup feed drive PCB. (Connection of the connector, Breaking (Breaking (shorting)), Wire caught by parts) Sensor side: J8981, PCB side: J898, J1470 2. Check the connection of the 24 V Power Supply connector. 3. Replace the Waste Toner Full Sensor. 4. Replace the 24 V Power Supply.

• Code: E014-0001
• Description: Fixing motor error (At start-up). Locking was not released within 3 seconds after the fixing motor was turned on.
• Remedy: Because the DC Controller turns OFF the 38 V Power Supply when an error is detected, it is needed to restart and check the power output before the machine detects the error to determine whether the cause of the error is power supply. If there is no power output, power supply is the cause. If there is power output, factor other than power supply can be the cause of the error. 1. Check the fixing unit drive gear -> replace the gear 2. Replace the fixing motor (M48) 3. Replace the pckup feed drive PCB. 4. Check the connection of the 38 V Power Supply connector. 5. Replace the 38 V Power Supply. 6. Replace the DC controller PCB

• Code: E014-0002
• Description: Fixing motor error (At regular rotation). Locking was released for 1 second consecutively after the fixing motor (M48) was locked.
• Remedy: 1. Check the fixing unit drive gear -> replace the gear 2. Replace the fixing motor (M48) 3. Replace the pickup feed drive PCB. 4. Replace the DC controller PCB
