Print quality problems (cont'd.)

Symptom	Solution
Streaks or spots	Most spots are caused by fingerprints or dust introduced into the printer while installing
	the Imaging Unit or loading media.
	Make sure that the surface where you unpack the Imaging Unit, paper, and
	transparencies is free of dust. Keep supplies in a covered area or a closed box.
	Make sure that the Imaging Unit stays covered until immediately before installing it in the
	printer. Exposure to light for more than 3 minutes can damage the Imaging Unit.
	Do not touch the right side or underside of the Imaging Unit; fingerprints affect print
	quality.
	Make sure that the media is clean.
	Make sure that you handle the media on the outside edges to avoid fingerprints.
	To get rid of fingerprint spots, print a few prints (you can print any of the Help Pages in
	the front panel menu).
The back of the printed	Toner particles have contaminated the transfer roller. This can happen if the printed
page appears dirty.	image is larger than the media (for example, when printing on envelopes). Run
	10-20 prints to clean the transfer roller.
Black-and-white prints	If you have a Macintosh
instead of color	Make sure that you are using the Phaser 560 printer driver, the Phaser 560 GX printer
	driver, or the correct PPD file with the latest Apple LaserWriter printer driver (version
	6.0.7 or higher), which supports color PostScript.
	Make sure that Color/Grayscale is selected in the Print dialog box. Some applications
	require special files to print in color. Make sure that these files are properly installed. For
	information, refer to the topics on the printer’s CD-ROM or the Tektronix World Wide Web
	site.
	Make sure that you have not selected Fast Monochrome in the Print-Qualitydialog
	box.
	If you have a PC
	Be sure to use a driver that supports color PostScript. If you are using Windows 3.1, use
	the Phaser 560 printer driver.
	If you are using Windows, make sure that the Color box in the Options dialog box is
	checked. For information on the drivers, refer to the printer’s CD-ROM or World Wide
	Web topics.
	Make sure that you have not selected Fast Monochrome in the Tektronix Printer
	Features dialog box.
	If you are not using a driver, make sure that you have not set the monochrome mode
	selection code; make sure that the front panel is not set for Fast Monochrome.
Blue colors look too	If printed blue colors look too purple, print your document with the Vivid Color color
purple	correction. Refer to “Color corrections” on page 4-24 or “Deciding which color correction
	to use” on page 5-18 for instructions and more information.
