Paper Motion Faults

During Online printing with the T6090 and T6091 printers, the printer may stop with a fault and indicate a Paper Motion Fault in the Control Panel Display. This is because the motion of paper past the paper motion sensor is not being correctly monitored.

There is more than one reason why this could happen and most of these reasons are hardware related failure or paper not installed in the tractors correctly. However, it could just be that the sensor is not set up correctly and setting it up correctly may save much time in repairing the printer.

To check the sensor, follow this procedure.

Set the printer to Offline.
Press the Enter and Line Feed keys together and hold pressed until the alarm sounds (typically 3 or 4 seconds).
You should have seen briefly displayed, Tech Access On
The display will again say Offline.
Press the Mode Key, display will show Offline Normal.
Press either Arrow key until display shows Offline Test.
Press the Forms/1 key.
Press either Arrow key until display shows Test Diag.
Press the CPI/2 key.
Press either Arrow key until display shows Diag PMotThr.
Press the LPI/3 key.
Press either Arrow key until display shows PMotThr 175.
Press the Enter key and an asterisk will appear.
Press the Clear key.

And finally turn the printer power off, wait ten seconds and turn the printer power on again.

Continue printing but if the fault appears again, you will need a repair to the printer.
