paper set in the MP tray.
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.
No Paper
Load #S paper in MP Tray.
<User Check>
• Set the paper in the MP tray.
Step Cause Remedy
1
MP paper empty actuator 1 or 2
caught in some sections of the
machine
Reattach the MP paper empty actuator 1 or 2.
2
MP paper empty actuator 1 or 2
failure
Replace the MP paper empty actuator 1 or 2.
3
MP paper empty sensor failure Refer to "1.3.10 Check sensor operation
(function code: 32)" in Chapter 5 to check the
sensor operation. If the sensor operation is
faulty, replace the MP paper empty sensor
PCB ASSY.
4
High-voltage power supply PCB
failure
Replace the high-voltage power supply PCB
ASSY.
5 Main PCB failure Replace the main PCB ASSY.
No Paper
Load #S paper in #T1.
<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 failure Replace the T1 paper feed actuator.
4
T1 paper feed sensor failure Refer to "1.3.10 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.
