PROBABLE CAUSE
Curled or wrinkled paper has jammed in the paper
transport path.
The transport roller in the duplex unit is slipping.
Curled or wrinkled paper has jammed.
Not closed after a jam was removed.
The difference in the pressure between the half-
locks of the reverse guide on the left and right side
(if both are not locked correctly) can cause the
paper to skew, preventing the paper from feeding in
the paper path.
The transport belt is dirty, resulting in an insufficient
amount of attraction between the belt and the paper
which allows the paper to float out of the paper feed
path.
1. Duplex unit gears damaged.
2. Transport roller in duplex unit dirty.
3. Charge roller is dirty, scarred, or damaged.
4. High voltage PP damaged.
5. Sensor damage (trailing edge sensor).
6. Harness disconnected, damaged.
