caused by worn parts in the mainte-
nance station. Go to and perform the
“Maintenance Station Service Check”
on page 12, then return to this check.

caused by paper problems or prob-
lems in the paper feed area. Check:
• Correct type of paper is in the
machine. Also check the paper for
curl and wrinkles.

ness
