Symptom

Frequent jams at the Duplex
Unit
Margins on the first side and
second side of a duplex print
are not aligned
Second side of a duplex print
is upside-down
Printed colors are not what you expected
Symptom
Prints have dull, faded colors
Solution
Make sure that you have installed the Lower Tray Assembly and that the Duplex Unit is
inserted in the upper slot of the printer.
Make sure that you have loaded the paper tray with paper and installed it in the middle or
lower slot of the printer.
Make sure that you have configured your printer driver to recognize the Lower Tray
Assembly and Duplex Unit. Refer to the printer's Setup Guide for instructions.
Make sure that you have made the selection for duplex printing, using one of these
methods (driver selections override other settings):
Front Panel: Under Duplex in the Printer Defaults menu.
Print screen: Using a supported driver, select Print on Both Sides or 2-Sided
Printing.
Use only laser paper.
Laser paper must be between 75 - 90 g/m
Clean the rollers inside the Duplex Unit with 90% isopropyl alcohol. Print the Cleaning
Instructions from the front panel's Cleaning menu.
Adjust the margins using the front panel Margin Adjust menu. Instructions are
included in this menu. For more details, see page 33.
Select the correct method for binding preference in the front panel or the Print screen.
Long-edge binding: Page turns on the long side, regardless of image orientation.
Short-edge binding: Page turns on the short side, regardless of image orientation.
Refer to "Automatic duplex" on page 26 for detailed instructions.
Solution
If you are using a media tray, make sure that you have loaded the correct media in the
tray or
PAPER TRANSPARENCY
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 Service Print 1 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 % 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.
Make sure that the Toner Cartridges are installed correctly.
Make sure that you use a high-quality laser paper: 60 - 90 g/m
media trays and 75 - 150 g/m
"All about media" on page 5 for more information.
Use only Tektronix transparencies. Tektronix does not guarantee the results of
non-Tektronix transparencies in Tektronix printers.
Try a different color correction mode.
