To set up the printer with DSL

1. Obtain a DSL lter from your DSL provider.

2. Connect one end of the phone cord to the DSL lter, and then connect the other end to the port labeled

1-LINE on the back of the printer.

NOTE: You might need to connect the phone cord to your country/region adapter.

If you do not use the supplied cord to connect from the DSL lter to the printer, you might not be able to

fax successfully. This special phone cord is dierent from the phone cords you might already have in

your home or oice.

You might need to obtain additional phone cords for this setup.

3. Connect an additional phone cord from the DSL lter to the telephone wall jack.

4. Run a fax test.

If you encounter problems setting up the printer with optional equipment, contact your local service provider

or vendor for further assistance.

Case C: Set up the printer with a PBX phone system or an ISDN line

If you are using either a PBX phone system or an ISDN converter/terminal adapter, make sure you do the

following:

● If you are using either a PBX or an ISDN converter/terminal adaptor, connect the printer to the port that

is designated for fax and phone use. Also, make sure that the terminal adapter is set to the correct

switch type for your country/region, if possible.

NOTE: Some ISDN systems allow you to congure the ports for specic phone equipment. For

example, you might have assigned one port for telephone and Group 3 fax and another port for multiple

purposes. If you have problems when connected to the fax/phone port of your ISDN converter, try using

the port designated for multiple purposes; it might be labeled "multi-combi" or something similar.

● If you are using a PBX phone system, set the call waiting tone to "o."

NOTE: Many digital PBX systems include a call-waiting tone that is set to "on" by default. The call

waiting tone interferes with any fax transmission, and you cannot send or receive faxes with the printer.

Refer to the documentation that came with your PBX phone system for instructions on how to turn o

the call-waiting tone.

● If you are using a PBX phone system, dial the number for an outside line before dialing the fax number.

● You might need to connect the phone cord to your country/region adapter.

If you encounter problems setting up the printer with optional equipment, contact your local service provider

or vendor for further assistance.

Case D: Fax with a distinctive ring service on the same line

If you subscribe to a distinctive ring service (through your telephone company) that allows you to have

multiple phone numbers on one phone line, each with a dierent ring pattern, set up the printer as described

in this section.
