<User Check>
- Load paper in the paper tray 1.
■ Error code 95
No paper in paper tray 2.
<User Check>
- Load paper in the paper tray 2.
- Check if paper is properly loaded in the paper tray 2. (Check of connector connection)
No Paper
Load <size> paper in Tray 1.
Step Cause Remedy
1 Coming off of registration front
actuator
Re-assemble the registration front
actuator.
2 Harness connection failure of T1
registration front/rear sensor
PCB ASSY
Check the harness connection of the
T1 registration front/rear sensor PCB
ASSY and reconnect it.
3 Registration front sensor failure Check the sensor performance following
the procedure described in “Function code
32”. If any problem occurs, replace the T1
registration front/rear sensor PCB ASSY.
4 Engine PCB failure Replace the engine PCB ASSY.
5 Main PCB failure Replace the main PCB ASSY.
No Paper
Load <size> paper in Tray 2.
Step Cause Remedy
1 T2 paper edge actuator
malfunction
Re-assemble the T2 paper edge actuator.
2 Harness connection failure of
T2 sensor PCB ASSY
Check the harness connection of the
T2 sensor PCB ASSY and reconnect it.
3 Harness connection failure of
T2 Relay PCB ASSY
Check the harness connection of the
T2 Relay PCB ASSY and reconnect it.
4 Harness connection failure of
plate drive motor
Check the harness connection of the
plate drive motor and reconnect it.
5 T2 paper edge sensor failure Check the sensor performance following
the procedure described in “Function code
32”. If any problem occurs, replace the T2
paper feed frame unit.
6 T2 Relay PCB failure Replace the T2 Relay PCB ASSY.
7 Engine PCB failure Replace the engine PCB ASSY.
8 Main PCB failure Replace the main PCB ASSY.
