 Error code 9400
When printing from paper tray 1, the T1 paper feed sensor detected that there was no paper
set in paper tray 1.
 Error code 9500
When printing from paper tray 2, the T2 paper feed sensor detected that there was no paper
set in paper tray 2.
No Paper
<User Check>
• Set the paper in paper tray 1.
Step Cause Remedy
1
Connection failure of the T1
paper feed sensor harness
Check the connection of the T1 paper feed
sensor PCB harness, and reconnect it if
necessary.
2
T1 paper feed actuator caught
in some sections of the machine
Reattach the T1 paper feed actuator.
3
T1 paper feed actuator is bent
or has failed
Replace the T1 paper feed actuator.
4
T1 paper feed sensor failure Refer to "1.3.8 Check sensor operation
(function code: 32)" in Chapter 5 to check the
sensor operation. If the sensor operation is
faulty, replace the T1 paper feed sensor PCB
ASSY.
5
High-voltage power supply PCB
failure
Replace the high-voltage power supply PCB
ASSY.
6 Main PCB failure Replace the main PCB ASSY.
