Print Quality Service Check

Before you perform the Print Quality Service Check, do the
following:

The toner cartridge can cause a variety of print quality prob-
lems. Be sure the toner cartridge is in good condition, works
correctly, and is not low on toner. If in doubt, install a new toner
cartridge before you proceed. The printer does not have a toner
sensor. If the print is light, remove the toner cartridge and gently
shake it to evenly distribute the toner.

Turn PQET off.

Set the print darkness setting to normal.

Place the printer in the 300 dpi mode.

Be sure the printer is clean, especially around the paper path,
print cartridge, and photoconductor unit.

Some types of paper can cause print quality problems. Print
quality problems can also be caused by extreme environmental
conditions like high temperature and humidity.

An incorrect printer driver for the installed software can cause
problems. Incorrect characters could print and the copy may not
fit the page correctly

Turn off PostScript on model 4026-06D before performing the
Print Quality Service Check.

FRU

Action

1

Toner Car-
tridge

Be sure the cartridge is installed correctly and
not low on toner. Be sure the toner cartridge
drive operates correctly.

2

Photoconduc-
tor Unit

Be sure the photoconductor unit is correctly
installed and the cartridge drive is operating cor-
rectly.

If you have vertical marks or horizontal black
bars on the page and these marks or bars are
126 mm (4.9 inches) or 55 mm (2.2 inches)
apart, check the photoconductor unit.

3

Transfer
Assembly

Replace the transfer assembly if you have a hor-
izontal black bar 57 mm from the top of page.
