Front panel indications

Media tray indicates missing or empty when it is not

1. If there is media in the tray, then check the media sensors. If the lower
feeder is available, switch trays to verify the source of the problem
2.
Check to see if the paper-empty sensor is broken.
3.
Run service diagnostics on the media sensors.
4. Check the media selection switch actuators on the rear of the paper tray.
Also check the paper size switches at the rear of the printer frame or the
lower feeder.

Macintosh printing problems

Image never prints

Printer acts as if it is receiving data, but nothing comes out of printer or it goes
back to "Ready" mode without printing image.
1.
Power cycle the printer and print again.
2.
Make sure that the correct Phaser 780 printer icon was selected in the
Chooser. Try printing the job again.
3. In the Chooser or the print dialog, switch background printing to off. Try
printing the job again.
4. Ensure that the printer can print by printing an internal front panel test
print.
5.
Enable the Error Handler through the front panel and try printing the job
again. If an error page is printed after printing the job again, call the
Customer Support Hotline for further assistance. Please have the error
page in hand.
If available, try printing to a black-and-white PostScript printer (such as
an Apple LaserWriter). If the file does not print on the black-and-white
PostScript printer, this may mean that the problem may be application- or
network-related.

Image prints in black-and-white

1. In the print driver dialog box, make sure the Color/Grayscale option has
been selected.
2.
Check the version of your LaserWriter driver to ensure that it is version
6.0.7 or higher. Earlier versions of the driver do not support color
PostScript. The application may require special instructions to print.
3.
Ensure the driver setting TekColor is not set to Monochrome mode.
