C238 Paper stuck is

delivery side plates and
end plate are not right. Adjust the position of paper delivery
side plates and end plate to fit the
paper size.
C249
C238 A paper
delivery jam
sometimes
occurs when
continuously
printing many
sheets. The paper scratches the
paper delivery unit wing
tips, and this increases
the static electricity
buildup in the area. The
static buildup eventually
overcomes the force of
paper delivery, triggering
the jam. C238/C249:
1. Install the metal wing set.
