SYMPTOM
Paper jams occur when feeding from the LCT. The characteristics of this problem
are as follows.
1. Constant jams from LCT installation onwards.
2. Non-paper feed jams.
3. Sometimes there is a crease in the central part of the leading edge of the paper,
which results in skewing.
CAUSE
There is a burr in the welded area of the entrance guide plate in the LCT paper feed
section.
SOLUTION
When this problem occurs in machines in the field or when installing an LCT on which the
countermeasure has not been implemented, please check for burrs in the following
manner.
1. Remove the paper feed unit of the LCT.
2. Carefully insert a piece of OHP sheet along the entrance guide plate as shown.
