EPSON Stylus Pro 9000

SMUDGED OR MARRED PRINTOUT (FRONT)

The front, or top, side of the paper can become smudged or marred if it rubs
against the printhead surface. If this happens, check 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 15 mm on the control panel.
(If a print job uses heavy ink coverage and the top and bottom margins are
set to 3 mm, the high volume of ink can cause the paper to warp and rub
against the printhead surface.)
2. If this problem recurs, check the Capping Assembly retention spring. If the
spring is broken or comes off its hook, the Capping Assembly cannot clean
ink off the printhead properly, and the ink will smudge the printout. Fix or
replace the spring.

SMUDGED OR MARRED PRINTOUT (REVERSE SIDE)

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


Paper Feed Roller


Paper Pressure Rollers


Lower Paper Guide
If the problem is not caused by ink on these parts, most likely the paper
jammed in the printer or curled up after being ejected.
Troubleshooting

WHITE OR BLACK BANDING

If white or black banding (lines across the page) appear on your printout, try the
following:
1. Run a printhead cleaning cycle. Press the Cleaning button and hold it for
3 seconds. For more intensive cleaning procedures, see
on page 128.
2. If multiple cleaning cycles don't eliminate the banding, perform the
following adjustments in the order listed below:


B Head Slant/C Head Slant Adjustment (Head Angle)
