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 30.

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.

Disconnect other equipment temporarily

To ensure the printer is working correctly, connect it directly to the telephone line. Disconnect any answering machines, computers with modems, or telephone line splitters.

Check for paper jams

Check for and clear any paper jams.

Disable Call Waiting temporarily

Call Waiting can disrupt fax transmissions. Disable this feature before sending or receiving a fax. Contact your telephone company to obtain the keypad sequence for temporarily disabling Call Waiting.
