PAPER EDGE SENSOR
ERROR
SKEW PULSE ERROR
•
The difference between the maximum and minimum Paper
Sensor values falls below the specified level during the sensor
instruction operation.
Check to determine whether paper is loaded into the printer during
the sensor instruction operation. (This error also occurs if paper is
not loaded properly due to a paper jam.)
Check the connection of the Paper Sensor harness. If it is
connected properly, replace the Paper Sensor or the Main PCB.
•
The printer fails to acquire the criteria for skew detection during
the sensor instruction operation.
Check to determine whether paper is loaded into the printer during
the sensor instruction operation. (This error also occurs if paper is
not loaded properly due to a paper jam.)
Check the connection of the Edge Sensor harness and the
connection of the Skew Sensor harness. If they are connected
properly, replace the Edge Sensor, the Skew Sensor, or the Main
PCB.
