1. Check the position of retained paper. If the paper is retained in the Fusing Unit, it could be due to any of the following cause (1) to (4). Check the image on retained paper in the Fusing Unit and check the paper for damage.
(1) Check the margin at the Lead Edge. If the margin is narrow, perform the following:
Adjust the Lead Edge margin.
Check for multi-sheet feed.
Reload the paper in the Tray.
(2) Check whether the Toner Density is dark. If the density is dark, perform Density Adjustment.
(3) Check whether the margin at the Lead Edge has narrowed due to skew. If the margin is narrow, reload the paper in the Tray correctly.
(4) Check whether the paper is being damaged by the Chute or the Actuator. If the paper is being damaged, use a fresh paper to check. (It is also possible that the paper had lost its stiffness due to its water content)
2. If there is no retained paper in the Fusing Unit, or if the problem persists after performing the above procedure, check the following:
The Fusing Unit Exit Sensor (DC330 [077-101]) for operation failure. (PL 7.1)
The Fusing Unit Drive Motor for operation failure. (PL 3.1, PL 3.2)
- High model: DC330 [010-001]
- Mid/Low model: DC330 [010-002]
The Fusing Unit for wound up, stuck paper.
The 2nd BTR for transportation failure due to contamination, wear, and revolution failure.
The P/Roll of Fusing Unit for improper Latch.
The Fusing Unit Exit Chute for improper installation and deformation.
The Drive Gear for wear and damage.
Transportation failure due to foreign matter on the paper path.
Usage of out of spec paper.
If no problem is found, replace the Motor Drive PWB. (PL 18.2, PL 18.5) |
