Are you using a surge-protection device? A surge-protection device can be used between the wall jack and the fax accessory to protect the fax accessory against electrical surges passed through the phone lines. These devices can cause some fax communication problems by degrading the quality of the phone signal. If you are having problems sending or receiving faxes and are using one of these devices, connect the printer directly to the phone jack on the wall to determine whether the problem is with the surge-protection device. Are you using a phone company voice-messaging service or an answering machine? If the rings-to-answer setting for the messaging service is lower than the rings-to-answer setting for the fax accessory, the messaging service answers the call, and the fax accessory cannot receive faxes. If the rings-toanswer setting for the fax accessory is lower than that of the messaging service, the fax accessory answers all calls. Does your phone line have a call-waiting feature? If the fax telephone line has an activated call-waiting feature, a call-waiting notice can interrupt a fax call in progress, which causes a communication error. Ensure that a call-waiting feature is not active on the fax telephone line.
