If you are using a media tray, make sure that you have loaded the correct media in the

PAPER

tray or

TRANSPARENCY

tray.

■

If you are using the Multi-Purpose Tray, make sure that you have selected the correct
media type in the printer’s front panel.

■

Print the Color Reference Page from the front panel’s Calibrate Colors menu. Check
the density settings for each color and compare them to the examples on the Color
Density Samples card. (in the User Guide).

■

Print the Consumables Page and Diagnotic Test Pages from the front panel’s Help
Pages.

■

If all colors are faded on the Test Print, the Imaging Unit may need to be
replaced. Refer to the Percent Remaining gauge for the Imaging Unit on the
Consumables Page.

■

If one color is faded (and you have checked and/or adjusted the density setting
for that color), replace the Toner Cartridge.

■

Make sure that the Imaging Unit stays covered until immediately before installing it
in the printer. Exposure to light can damage the Imaging Unit and will produce light
streaks or faded prints.

■

Remove and insert the Toner Cartridges to make sure they are installed correctly.

■

Make sure that you use a high-quality laser paper: 60 - 90 g/m

(16 - 24 lb.) paper in

the media trays and 163 g/m

(40 lb.) paper with the Multi-Purpose Tray. For best

results use Tektronix media.

■

Use only Tektronix transparencies. Tektronix does not guarantee the results of
non-Tektronix transparencies in Tektronix printers.

■

Try a different color correction mode.
