Remote troubleshooting (call agent) Switch the power off and disconnect the power cord. Reconnect the power cord and power on the printer. Go to the Support Menu (see Entering the Service Menu for Service Engineers on page 315) and run Paper Servo diagnostic. After running the diagnostic the printer will show one of these system errors: 0081-0008, 0041-0017 or 0041-0117: arrange a service engineer to replace Paper/ Feed motor and follow the Onsite Troubleshooting explained below, see Paper Motor (F9A30-67049) on page 541. – Paper Motor 0085-0101 need to replace Feed encoder sensor PCA and follow the Onsite troubleshooting and solution (service engineer) explained for error 0085-0201. 0085-0201 need to replace Feed encoder sensor PCA and follow the Onsite troubleshooting and solution (service engineer) explained for error 0085-0201. The call agent should arrange a service engineer visit to replace the right part depending on the system error. Onsite troubleshooting and solution (service engineer) Remove covers and check that all the cables are well connected to the Main PCA, specially the paper motor cable, and none of them are damaged. If any of the cables is not connected, then reconnect it, and power on the printer again to check whether the system error has disappeared. Check that there are no debris, media or foreign objects preventing drive shaft movement. IMPORTANT: If any cable is damaged then order a Cable Service Kit: Cables and sensors Go to the Service Menu (see Entering the Service Menu for Service Engineers on page 315) and run Paper Servo diagnostic. After running the diagnostic check for the following system errors: After running the diagnostic the printer will show one of these system errors: 0081-0008, 0041-0017 or 0041-0117: arrange a service engineer to replace Paper/ Feed motor and follow the Onsite Troubleshooting explained below, see Paper Motor (F9A30-67049) on page 541. – Paper Motor 0085-0101 need to replace Feed encoder sensor PCA and follow the Onsite troubleshooting and solution (service engineer) explained for error 0085-0201. 0085-0201 need to replace Feed encoder sensor PCA and follow the Onsite troubleshooting and solution (service engineer) explained for error 0085-0201. If the 0041-0017 error continues then the Paper/Feed motor should be replaced. See Paper Motor (F9A30-67049) on page 541. Paper Motor Replace the Main PCA, see Main PCA (2Y9H0-67016, 2Y9H1-67015, 2Y9H2-67002, 2Y9H3-67003) on page 517. Main PCA System error:
