FUNCTION MCMTR3
ERROR
FUNCTION MCMTR4
ERROR
RIGHT EDGE SENSOR
ERROR
LEFT EDGE SENSOR
ERROR
• The MC Sensor (Front Tractor) detects an error when the printer is
initialized or when the paper feed path is changed.
Check to determine whether anything is obstructing the operation of
the Front Tractor Motor.
Check the connection of the MC Sensor (Front Tractor) harness. If
it is connected properly, replace the MC Sensor (Front Tractor) or
the Main PCB.
• The MC Sensor (Rear Friction) detects an error when the printer is
initialized or when the rear friction is adjusted.
Check to determine whether anything is obstructing the operation of
the Rear Friction Motor.
Check the connection of the MC Sensor (Rear Friction) harness. If
it is connected properly, replace the MC Sensor (Rear Friction) or
the Main PCB.
• The difference between the maximum and minimum Skew 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 to ensure that the Skew Sensor is mounted properly, the
Skew Sensor harness is connected properly, and the FFC harness
between the Main PCB and the Head Connecting PCB is
connected properly. If they are mounted or connected properly,
replace the Skew Sensor or the Main PCB.
• The difference between the maximum and minimum Edge 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 to ensure that the Edge Sensor is mounted properly, the
Edge Sensor harness is connected properly, and the FFC harness
between the Main PCB and the Head Connecting PCB is
connected properly. If they are mounted or connected properly,
replace the Edge Sensor or the Main PCB.
