Lexmark 901, 90T9251 Cannot run the fax software, Fax error messages on the printer control panel

Troubleshooting 161

MAKE SURE THAT YOU HAVE THE CORRECT MANUAL ANSWER CODE

If you set the printer to receive faxes manually (Auto Answer Off), then you need to enter the correct code when a fax comes in so that the printer can receive it.

1From the home screen, navigate to:

> Fax Setup > Ringing and Answering > Manual Answer Code

2Copy the manual answer code that appears on the touch screen.

Note: The default code is *9*, but for increased security, you can change it to a number that only you know.

Cannot run the fax software

The printer must be connected to a telephone, DSL, VoIP, or cable service before you can configure the fax settings in the fax software.

MAKE SURE A FAX DRIVER IS INSTALLED

The fax option is available for use only with the PostScript driver or the Universal Fax Driver. For information on installing these drivers, see the Software and Documentation CD.

MAKE SURE THE PRINTER IS CONNECTED TO A TELEPHONE LINE

You need to connect the printer to your telephone line (through a standard wall jack, a DSL filter, a VoIP adapter, or a cable modem) before you can open the fax software and configure the fax settings.
