TB 18 / Paper feed jam at the 250-sheet cassette
2KT-D027/M
Date: 06-03-2013
Only  CLP 3721 / CLP 4721
T OPIC :
Depending on the backlash to the cassette length direction, the 250-sheet cassette is incompletely inserted into the machine
but the cassette feed drive can be driven (The bottom plate is lifted up when feeding the paper from the cassette).
STOPPER HOOOK at the cassette rear side may hook the lever holding the paper (X in the figure below) at the machine
inside at their contact faces in the above state, and STOPPER HOOK does not rotate under its own weight while the bottom
plate is lifted up to feed the paper, and the lever (X) cannot return and continues to hold the paper, and so, the no paper
feed jam (JAM0501) may occur.
C ONTENT OF CHANGES :
The shape of STOPPER HOOK (No.1) is changed and SPRING STOPPER HOOK (N) is added to improve the operability of
STOPPER HOOK when feeding the paper from the cassette with the bottom plate lifted up.
Normal state State when the phenomenon occurs
250-sheet cassette
Insert
Bottom plate
When the bottom plate is lifted up by
the cassette feed drive, the lever (X)
returns for distancing from the
cassette after STOPPER rotates
under its own weight, and then the
cassette paper feed starts.
STOPPER doesn’t rotate since it is
hooked at the contact faces after the
bottom plate is lifted up, and the
lever (X) cannot return. As a result,
no paper feed jam (JAM0501)
occurs.
