FRU OR PROCEDURE

ACTION

 

 

 

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.
