Troubleshooting Problems with jams
Symptom Solution
Frequent paper-picking errors Make sure that the Media Thickness Switch is set correctly for the media installed in the
Multi-Purpose Tray . Refer to page 13 for details on setting media thickness. If the printer
picks multiple sheets of paper at once, set the Media Thickness Switch to a thinner
setting.
Fan the paper or transparencies before installing them in their respective trays; this is
especially important for transparencies because they tend to stick together.
Make sure that the media is installed under the hooks at the front of the media tray.
If printing on transparencies and your printer has the Automatic Duplex/Lower Tray
Assembly, make sure that the TRANSPARENCY tray is installed in the
middle
tray slot.
Clean the paper-feed rollers and paper-pick rollers. Print the instructions from the
Cleaning menu in the front panel.
Frequent media jams 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.
Make sure that the Media Thickness Switch is set correctly for the media installed in the
Multi-Purpose Tray. If the printer has frequent paper jams, set the Media Thickness
Switch to a thicker setting. Refer to page 13 for more information.
If you are using media that is 105 g/m2 (28 lb.), check if the Face Down media output
setting is selected in the driver. If it is, change the setting to Face Up. If the problem
persists, use the Multi-Purpose Tray rather than a media tray.
Use only Tektronix transparencies. Tektronix does not guarantee the results of
non-Tektronix transparencies in Tektronix printers.
Make sure that the media is installed under the hooks at the front of the media tray.
Do not overfill the media tray, as indicated by the red line on the right side of the tray.
Clean the paper-feed rollers and paper-pick rollers. Print the instructions from the
Cleaning menu in the front panel.
Media frequently wraps
around the Fuser. Replace the Fuser Roll.
Problems with image size and position
Symptom Solution
Off-set images Check your application for correct image sizing.
Cut-off images Check your application for image sizing.

your Macintosh so that you can select the correct page sizes from the driver.
If printing on transparencies and your printer has the Automatic Duplex/Lower Tray
Assembly, make sure that the TRANSPARENCY tray is installed in the
middle
tray slot.
