Print quality problems

Prints have dull, faded colors and significant dropout (areas where dye is missing)

■Make sure that you have selected the same media in the driver that is loaded in the paper tray and that it is loaded correctly (printing side down).

■Make sure that you are using Tektronix paper for the Phaser 480X. You can achieve excellent results with Tektronix supplies; they are tested and guaranteed to work with Tektronix printers.

Streaks or spots appear on prints

■Make sure that the paper or transparency Þlm is clean (see ÒHandling paper and transparenciesÓ on page 3-7).

■Make another print. If the problem persists, clean the thermal head. For cleaning information, see Chapter 4, ÒCaring for Your Printer.Ó

The image prints in black-and-white instead of color

■Make sure that a color transfer roll is installed in the printer.

■If you have a Macintosh, make sure that you are using the Phaser 480X driver or the latest Apple LaserWriter printer driver (version 6.0.7 or higher), that supports color PostScript.

■Make sure that Color/Grayscale is selected in the Print dialog box. Some applications require printer description files to print in color. Make sure that these Þles are properly installed. For information, refer to the Phaser 480X Drivers and Utilities Printing Reference.

■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 480X driver and make sure that the Color box in the Options dialog box is checked. For information on the drivers, refer to the Phaser 480X Drivers and Utilities Printing Reference.
