The front, or top, side of the paper can become smudged or marred if it rubs 
against the printhead surface. If this happens, verify the following.

1.

If the smudged area is just around the front or rear edge of roll paper, 
make sure the margins (top and bottom) are set to 15mm on the control 
panel.
(When printing high-duty print jobs with the top and bottom margins set 
to 3mm, the high volume of ink can cause the paper to warp and rub 
against the printhead surface.)

2.

Roll paper near the core tends to have excessive curl (especially with high 
duty print jobs), some ways to avoid head rubbing include:

„

After the paper initializes, feed the paper so that the leading edge is 
almost over the paper suction holes. This way, the paper suction fans 
take effect immediately and pull the paper flat against the lower 
paper guide before the printer starts to print

„

Print continuously when possible, for the same reason as described 
above

3.

If this problem recurs, check the Cap Assembly retention spring. If this 
spring is broken or comes off its hook, the Cap Assembly cannot wipe ink 
off the printhead surface, and that ink will smudge the printout. Fix or 
replace this spring.

The reverse side of the paper can become smudged or marred if there is ink 
on the printer parts. Make sure there is no ink on the following parts, and if 
there is ink, wipe off the affected parts.

„

Sub-platen surface

„

Grid roller surface

„

Lower Paper Guide surface

If the problem is not caused by the above, most likely the paper jammed in 
the printer or curled up after being ejected.

If white or black banding (lines across the page) appear on your printout, try 
the following.

1.

Cleaning

2.

If multiple cleaning cycles don’t clear the banding problem, try adjusting 
the heads as described below.

„

Head slant adjustment (B head/C head)
If all the nozzles in the B head and C head are not perfectly lined up, 
the raster lines will overlap. The unprinted area between one line and 
the next line (where a nozzle was supposed to fire but missed) is 
banding.

Head height adjustment (B head/C head)

„

Bi-directional print position adjustment
