Preventing wrapped paper in transfer (Measure against J31/J4X) PAGE 4
Phenomenon:
Paper may be wrapped around the primary transfer belt after primary transfer process,
and then J31 (Misfeed round the transfer belt) or J4X (Misfeed in fuser section: X is the
paper feeding source No.) may be displayed depending on the paper properties (weak
stiffness/upward curl/thinness).
Counter measure:
To prevent J31/J4X and the paper wrapping around the primary transfer belt, the paper
separation films (No.8, 9) are affixed in between the guide pulleys at the machine left side
of the primary transfer belt.
The paper separation film (2 each sheets of No.8, 9 or 3 sheets of No.9) and the
instruction leaflet are bundled in the primary transfer belt unit for service (No.1-7) and
MK kit A. NOTE: The film must be installed separatly!
