■Short-edge binding: Page turns on the short side, regardless of image orientation. Refer to “Automatic duplex” on page 26 for detailed instructions.

Printed colors are not what you expected

SymptomSolution

Prints have dull, faded colors ■ 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 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/m2 (16 - 24 lb.) paper in the media trays and 75 - 150 g/m2 (20 - 39 lb.) paper with the Multi-Purpose Tray. Refer to “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.
