• Code: 80:03
• Description: Stacker overdrive motor error
• Remedy: Call agent: 1. Use the power switch at the rear to turn off the printer, then disconnect the power cord. Reconnect the power cord, then turn on the printer. 2. Test the cutter. Perform a 'Form Feed & Cut', and verify the paper can be cut. 3. Perform the stacker overdrive motor diagnostic test to troubleshoot the problem further. 4. Reconnect the power cord, then turn on the printer. 5. Perform the stacker overdrive motor diagnostic test to troubleshoot the problem further. Service engineer: 1. Check that the stacker overdrive motor cable is undamaged and correctly connected to the engine PCA. 2. Replace the stacker overdrive motor. 3. Perform the stacker overdrive Service Calibration. 4. Check the system initializing the printer and performing a "form feed and cut" action, or printing a small job.

• Code: 81:01
• Description: Paper servo shutdown, possible paper jam
• Remedy: If this error is reported during printer setup, it may indicate that the printer has been dropped during transportation, causing structural damage. Before continuing with the 81:01 troubleshooting, first look for structural damage. To identify the structural damage, look for the following three things: • Consistent 81:01 error codes • Platen fingers rubbing on the roller surface, leaving black marks on the roller • A gap in the platen beam. If there is any gap in the vertical direction between the plastic of the platen and the metal side plate, then the chassis is damaged and the printer cannot be repaired. If no structural damage, continue with these steps: Call agent: 1. Check for any visible obstacles restricting the movement of the drive roller. If there is a wrinkled mass of paper inside the paper path, lift the pinchwheels and clear the obstruction. 2. Perform the paper drive diagnostic test to troubleshoot the problem further. Service engineer: 1. Check the connections on the engine PCA; the paper advance drive is connected to the connector labeled Paper Motor. 2. Adjust the encoder disc and motor mount configuration using the paper advance drive installation instructions. 3. Replace the paper advance drive.

• Code: 86:01
• Description: Scan axis servo shutdown, possible paper jam
• Remedy: Call agent: 1. Open the window and check for any visible obstacles restricting the movement of the carriage assembly. If there is a wrinkled mass of paper inside the paper path, lift the pinchwheels and clear the obstruction. 2. Turn off the printer and unplug the power cord. Try to move the carriage manually. Check that the cutter disengages correctly and that the carriage is not blocked by the service station. 3. Perform the scan-axis diagnostic to obtain further information on the problem. Service engineer: 1. Check the integrity and tension of the carriage belt. If the belt is damaged, replace it. 2. Lubricate the scan axis. 3. Perform a Encoder Strip verification and check it runs successfully.

• Code: 87:01
• Description: Problem reading the scan-axis encoder (advisory)
• Remedy: Call agent: 1. Use the power switch at the rear to turn off the printer, then disconnect the power cord. Reconnect the power cord, then turn on the printer. 2. Ensure that the encoder strip is clean. If it is dirty, clean it, paying special attention to the area near the service station. 3. Replace the carriage PCA.
