Image slipped out of
position at the
leading edge of the
paper
Paper tray was set without
pushing down the bottom
plate of the tray, causing the
leading edge to slip.
Can occur at the
beginning of
machine use or
over time.

Check installation of
the paper tray.
•
Adjust paper
registration in the

Poor Paper Transport
Problem Cause Details Solution
Tears occur in
the center of
paper leading
edges
Paper tray was set
without pushing
down the bottom
plate of the tray,
causing the leading
edge to slip.
Can occur after
adding fresh paper to
paper tray.
Can occur at the
beginning of machine
use or over time.
Check installation of the paper tray.
Both corners
of leading
edge become
dog eared
Dog-earing can be
caused by both
corners of the
leading edge getting
caught in the paper
transport path.
If the paper is thick
and has been left
unwrapped for a long
time, or it is recycled
paper, replace with
normal paper.
•
Confirm that paper is set
correctly in the tray. (Problems
can occur with leading/trailing
edges, front/back sides of
paper in the paper feed path
with paper from different lots.)
•
Make sure that paper is stored
correctly in its vinyl packs until
ready for use.
Paper double
feeds
Paper in the feed tray
can easily stick
together.
Leading edges of the
paper are burred.
Fan the paper stack before loading
it in the tray (this gets air between
the sheets of paper).
