EPSON WF-7820 Series, WF-7830 Series, WF-7840 Series/EC-C7000 Revision A Troubleshooting Fatal Error Code List 61 Confidential 2.3.2.3 Printer (PF) Table 2-4. Printer (PF) Error code Error name Possible cause Confirmation procedure Connector No. 000040 PF PID driving time error Malfunction or crash of the firmware The PE sensor remains in paper detection status and a paper jam error occurs instead of causing a fatal error. 1. Turn the printer off and back it on. 2. If the error still occurs after the restart, replace the Main Board. --- 000041 PF PID excess load error The PF Motor stopped running in the middle of the operation 1. The PF was stopped by; • Obstacles such as jammed paper • Overload of the paper feed mechanism • Disengaging or breakage of the gears Failed to read the PF Encoder 2. The timing belt become frayed or jumping 3. Contamination of the PF Scale 4. Disconnection, break, skew or damage of the PF Motor cable/Encoder FFC 5. Failure of the PF Motor (not completely broken) 6. Failure of the Main Board Failed to read the PF Encoder 1. Contamination of the PF Scale 2. Skew or damage of the PF Encoder FFC 3. Failure of the PF Encoder Failure of the PF Motor driver 4. Failure of the Main Board Paper feed fails, stopped by obstacles 1. Paper feed was stopped by; • Obstacles such as jammed paper • Overload of the paper feed mechanism • Disengaging or tooth breakage of wheel train of the paper feed mechanism Failed to read the PF Encoder 2. Jumping of the PF Timing Belt 3. Contamination of the PF Scale 4. Skew or damage of the PF Encoder FFC 5. Failure of the PF Encoder 6. Failure of the Main Board 1. Check that no pieces of paper or foreign objects exist in the paper path. 2. Check the load of the paper feed mechanism. 3. Check the wheel train of the PF drive and the Timing Belt for damaging or looseness. 4. Check the PF Scale for damage or contamination. 5. Check the PF Encoder FFC or the connector. 6. Replace the PF Motor with a new one. 7. Replace the Main Board with a new one. Main Board •CN201 •CN703 000042 PF PID excess speed error 1. Clean the PF Scale if it is contaminated. 2. Check the PF Encoder FFC or the connector. 3. Replace the PF Encoder with a new one. 4. Replace the Main Board with a new one. 000043 PF PID reverse error 1. Check that no pieces of paper or foreign objects exist in the paper path. 2. Check the load of the paper feed mechanism. 3. Check the wheel train of the PF drive and the PF Timing Belt. 4. Clean the PF Scale if it is contaminated. 5. Check the PF Encoder FFC or the connector. 6. Replace the PF Encoder with a new one. 7. Replace the Main Board with a new one.
