Persistent 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.
86:01 Scan axis servo shutdown, possible paper jam
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.
87:01 Problem reading the scan-axis encoder (advisory)
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. See Engine PCA on page 277.
