• 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 500msec (100msec x 5 times) consecutively
• Remedy: Pull out the waste toner bottle. If it is full of toner, go to Step 2. If the waste toner bottle is not full of toner, go to Step 1, 2, and 4. If the waste toner bottle is not full and the waste toner pipe is not clogged with toner, go to Step 3 and 4. 1. If the waste toner pipe is clogged with toner, remove the toner in the pipe. 2. Replace the waste toner full sensor and the waste toner bottle. Remove the toner clog in the waste toner pipe. 3. Replace the waste toner screw lock detection switch (SW10). 4. Replace the waste toner drive unit.

• Code: E013-0002
• Description: Waste toner full sensor offset adjustment error. The sensor sampling result is not within a specified range.
• Remedy: If the waste toner bottle is full of toner (if toner is viewable at the height of the detection window), go to Step 1. If the waste toner bottle is not full of toner (if toner is not viewable at the height of the detection window) and the detection window is stained with toner, go to Step 2. If the toner bottle is new, go to Step 3 and 4. If toner is not viewable at the height of the detection window and the window is not stained with toner while the waste toner bottle is not new, go to Step 3 and 4. If no fault is found after checking mentioned above is performed and the connector of the waste toner full sensor (TS9) is inserted, go to Step 4. 1. Replace the waste toner bottle with new one. If new one is not available, remove toner in the waste toner bottle. 2. Replace the waste toner bottle with new one. If new one is not available, clean the detection window in the waste toner container. 3. Check the connection between the waste toner full sensor (TS9) and the DC controller interface PCB. (Connection of the connector, Shorting, Wire caught by parts) Sensor side: J7010, PCB side: J1261, J8149 4. Replace the waste toner full sensor (TS9).

• Code: E013-0003
• Description: Waste toner full sensor error. Output of the waste toner full sensor cannot be detected.
• Remedy: 1. Check the connection between the waste toner full sensor (TS9) and the DC controller interface PCB (UN2). (Connection of the connector, Breaking (Breaking (shorting)), Wire caught by parts) Sensor side: J7010, PCB side: J1261, J8149 2. Replace the waste toner full sensor (TS9).

• 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: 1. Check the fixing unit drive gear -> replace the gear 2. Replace the fixing motor (M48) 3. Replace the fixing feed driver PCB 4. 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 fixing feed driver PCB 4. Replace the DC controller PCB

• Code: E015-0001
• Description: Decurler incoming amount control error 1. Change of the decurler HP sensor 1 (PS88) cannot be detected even when a specified time elapsed after driving of the decurler incoming amount adjustment motor 1 (M50) started.
• Remedy: 1. Turn OFF and then ON the power. 2. Check or Replace the decurler HP sensor 1 (PS88) 3. Check or Replace the decurler incoming amount adjustment motor 1 (M50) 4. Check or Replace the buffer driver PCB (UN150)

• Code: E015-0002
• Description: Decurler incoming amount control error 2. Change of the decurler HP sensor 2 (PS89) cannot be detected even when a specified time elapsed after driving of the decurler incoming amount adjustment motor 2 (M53) started.
• Remedy: 1. Turn OFF and then ON the power. 2. Check or Replace the decurler HP sensor 2 (PS89) 3. Check or Replace the decurler incoming amount adjustment motor 2 (M53) 4. Check or Replace the buffer driver PCB (UN150)

• Code: E020-0080
• Description: ITB base light intensity upper limit error. When executing ITB base correction, the average value of P wave light intensity detected/calculated is more than 900.
• Remedy: When the value of DISPLAY > DENS >P-LED-DA is large (153(D) or more) and the value of DISPLAY > DENS >P-SENS-P is small, there is a high possibility that dirt is applied to the patch sensor. This occurs only at a regular timing. When the value of DISPLAY>DENS>DENS-S-x is small (2 digits), there is a high possibility that breaking occurred. 1. Check whether the developing assembly and the drum unit are properly installed. 2. Clean the patch sensor. 3. Check the connection between the patch sensor and the DC controller interface PCB. (Connector, Shorting) Sensor side: J7412, J8035 PCB side: J1242 4. Check open/close operation of the patch shutter. 5. Clean or replace the ITB. Check whether the ITB belt is dirty or not. If it is dirty, perform cleaning with the following service mode. COPIER>FUNCTION>CLEANING>TBLT-CLN If it is assumed that this error occurred due to scratches on the ITB, replace the ITB. 6. Replace the patch sensor unit. 7. Replace the developing assembly.
