Frozen Fax - Stuck at Self Test

The fax machine won't move past the self test mode. I tried resetting the fax by unplugging and replugging in the power cord. I also tried rebooting the fax according to the procedures found on this site (function 7 / monitor key slowly 4 times / press */etc....). However, the fax does not even respond to pressing the function keys. Do you have any other suggestions? Thanks in advance for your help.

Can't receivee a fax. Machine stays in selftest mode

If it's out of ink, it would remain in sef test mode until it's able to print a report. Make sure the unit is plugged in and check the ink cartridge(s). This may have been the problem that initiated running the self test all along. Post back with any other questions or comments.

We just changed the toner in our fax, and now it's printing solid black pages out. Help!

Unplug the cable that connects the computer and printer together.
Plug the printer power cord into a wall outlet.
Print a self-test to determine if the problem is related to the printer, rather than the software.
If the problem occurs on the self-test page, replace the toner cartridge. A faulty or damaged cartridge may cause black pages.
Remove all accessories (cartridges, memory, I/O boards, etc.) and try to print a self-test again. Faulty accessories may cause black pages to be produced.
If the problem persists, the printer may need to be serviced.
