ACTION
Intermittent nozzle failures can be
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.
Ink smudging and smearing can be
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.
• Feed roller for wear, dirt, or loose-
ness
• Gears for wear or binds
• Paper path for obstructions
• Star rollers for binds or dirt. The exit
roller and star rollers keep tension
on the paper by moving slightly
faster than the feed rollers. A bind-
ing star roller can put vertical marks
on the paper.
Blurred print and voids can be caused
by problems in the transport area.
Check the following:
• Transport belt for wear.
• Carrier guide and carrier guide rod
for wear or dirt.
• Idler pulley parts for wear, damage,
or looseness.
• Encoder strip for wear or dirt.
Uneven vertical lines can be adjusted
by performing the
