Cannot send or receive a fax
These are possible solutions. Try one of the following:
Check messages
If an error message is displayed, follow the instructions on the display.
Check power
If the light is not on, see “Power button is not lit” on page 138.
Check cable connections
Make sure cable connections for the following hardware are secure, if applicable:
• Power supply
• Telephone
• Handset
• Answering machine
Check the telephone wall jack
1 Plug a telephone into the wall jack.
2 Listen for a dial tone.
3 If you do not hear a dial tone, plug a different telephone into the wall jack.
4 If you still do not hear a dial tone, plug a telephone into a different wall jack.
5 If you hear a dial tone, connect the printer to that wall jack.
Review digital phone service checklist
The fax modem is an analog device. Certain devices can be connected to the printer so that digital telephone services
can be used.
• If you are using an ISDN telephone service, connect the printer to an analog telephone port (an R-interface port)
on an ISDN terminal adapter. For more information and to request an R-interface port, contact your ISDN
provider.
• If you are using DSL, connect to a DSL filter or router that supports analog use. For more information, contact
your DSL provider.
• If you are using a PBX telephone service, make sure you are connecting to an analog connection on the PBX.
If none exists, consider installing an analog telephone line for the fax machine. For more information on faxing
when using a PBX telephone service, see “Setting up to fax while behind a PBX” on page 36.
Verify dial tone
• Place a test call to the telephone number to which you want to send a fax to make sure that it is working correctly.
• If the telephone line is being used by another device, wait until the other device is finished before sending a fax.
• If you are using the On Hook Dial feature, turn up the volume to verify a dial tone.
