7-105 Tray 1 Misfeed
The Tray 1 Feed Out Sensor does not detect paper after feeding from Tray 1.
Initial Actions
• Check condition and specification of paper in Tray 1.
• Check the paper path for obstructions.
• Check for wear and clean the Tray 1 Feed Roll, Takeaway Roll and the Pinch Roll.
Procedure
Open the Left Lower Cover (PL 2.3). Enter dC330 [008-100] and press Start. Block and
unblock the Tray 1 Feed Out Sensor (PL 2.3). The display changes.
YN
Press Stop. Check the circuit of the Tray 1 Feed Out Sensor (Figure 1). Refer to the OF
99-2 RAP for troubleshooting procedure.
Press Stop and close the Left Lower Cover. Enter dC330 [008-001] and press Start. The Tray
1 Feed/Lift Motor (PL 2.4) energizes.
YN
Press Stop. Check the circuit of the Tray 1 Feed/Lift Motor (Figure 2). Check the wires
from the I/F PWB to the Tray 1 Feed/Lift Motor for an open circuit. If the wires are good,
replace the Tray 1 Feed/Lift Motor (PL 2.4). If the problem still exits, replace the I/F PWB
(PL 9.1)
• Check the Tray 1 Feed / Lift Motor and its associated gears (PL 2.4) for damage, contam-
ination or misalignment.
• Ensure that the Tray 1 Chute (PL 2.3) is properly seated and not damaged.
• Ensure that the connectors shown in the circuit diagrams (Figure 1, Figure 2) are securely
connected and that the wires are not damaged.
• If these checks are OK, replace the I/F PWB (PL 9.1).
• If the problem persists, replace the MCU PWB (PL 13.1).
