4 Maintenance Station 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.
5 Paper Feed 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.
6 Transport 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.
7 BiDirectional Alignment Uneven vertical lines can be adjusted
by performing the
“Bi-directional
Alignment Adjustment” on page 31 .
