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 configure the ports for specific 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 "off."
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 off the call-waiting tone.
If you are using a PBX phone system, dial the number for an outside line before dialing the fax number.
Make sure you use the supplied cord to connect from the telephone wall jack to the printer. If you do not, you might not be able to fax successfully. This special phone cord is different from the phone cords you might already have in your home or office. If the supplied phone cord is too short, you can purchase a coupler from your local electronics store and extend it.
You might need to connect the supplied phone cord to the adapter provided for your country/region.
If you encounter problems setting up the printer with optional equipment, contact your local service provider or vendor for further assistance.
