Connecting the Telephone Lines and Configuring the Fax Settings

  • PrintPrint


This document describes how to connect the telephone lines to the HP Fax 1240 and configure the fax settings.

Changing fax settings

Depending on your fax line configuration, two fax settings might need to be changed. The two fax settings are listed below.

Changing the Rings to Answer setting

The Rings to Answer setting determines how many times the line will ring before the fax answers. Follow the steps below to change the rings to answer setting.
  1. Press Setup, press 3, and then press 3 again to access the Rings to Answer setting.
  2. Press the Right Arrow to scroll through the available settings. When the desired number of rings is shown in the display, press OK.

Changing the Answer Ring Pattern setting

Change the Answer Ring Pattern setting only if you use a Distinctive Ringing service on the line. Follow the steps below to change the ring pattern setting.
  1. Press Setup, press 4, and then press 1 to access the Answer Ring Pattern setting.
  2. Press the Right Arrow to scroll through the available settings. When the ring pattern set by the phone company appears in the display, press OK.

Using a two-conductor phone cable

The phone line cable used to connect the fax must be a two-conductor (wire) phone cable, like the one that shipped with the fax. The fax may fail to send or receive faxes if the phone cable has more than two conductors. To determine how many conductors the phone cable has, look at the end of the cable. Most phone cable connectors are clear and you can see the number of wires.

Using a two-conductor cable adapter

A four-conductor cable can be used with a two-conductor cable adapter. Connect the two-conductor phone cable adapter to the fax and then connect the phone line cable between the adapter and the wall phone jack.

Basic fax line connections

The fax must be connected directly to the wall phone jack. Connect any other phone line devices, such as a telephone or answering machine, to the phone jack on the back of the fax marked 2 - EXT.

Fax settings

The table below lists the necessary fax settings based on your connection. These settings apply to any phone-line device sharing the same phone line whether directly connected to the fax or connected through a different phone jack.
In situations where both manual and automatic answering are possible, the settings for both are listed. Set the correct answer mode setting using the Answer Mode button.
Phone line devicesAutomatic/Manual answeringAnswer Mode settingRings to answer

Telephone and answering machine with or without a PC modem1AutomaticAnswerMachine6
1 - When a dial-up PC modem is connected to the Internet, faxes cannot be sent or received until the modem disconnects from the Internet. A message will appear on the display to indicate that the line is busy if a telephone or PC modem is using the line.
2 - If the Answer Mode setting is set to FaxTel, the fax machine will automatically answer all incoming calls using the Rings to Answer setting. If the call is a fax call, the fax will be received; if the call is a voice call, the fax will create a special ring to indicate it is a voice call (other phones on the line will not ring at all.)
Answer the incoming voice call using the handset on the fax. Do not answer voice calls from other telephones on the line. The fax cannot detect when an extension phone is picked up and will keep ringing. Press Cancel to stop the ringing. If this is undesirable, use the Fax answer mode setting, or use the Tel setting and receive faxes manually.

Distinctive Ringing Service setup

While it is not available everywhere, a distinctive ringing service can be purchased from most telephone companies. With this service, more than one phone number is assigned to the same phone line. Each phone number will ring differently. The main number will ring with a normal single ring and the additional number will ring with a distinctive ring pattern assigned by the phone company.
When a distinctive ringing service is used, set the Rings to Answer to 2 and then follow the steps below to set the distinctive ringing pattern:
  1. Press Setup, press 4, and then press 1 to enter the Answer Ring Pattern setup of the Advanced Fax settings.
  2. Use the Right Arrow to scroll through the available settings. When the ring pattern assigned by the phone company displays (double or triple rings), press OK.

Phone line shared with a DSL modem

If you have a digital subscriber line (DSL) service through your phone company, use the instructions in this section to connect a DSL filter between the wall phone jack and your fax. This filter is provided by your phone company and removes the digital signal that would block your fax machine from communicating properly with the telephone line.
NOTE:If both the DSL modem and the fax machine must be connected to the same wall phone jack, connect the DSL modem first and then install the filter between the DSL modem and the fax machine.

Connecting the fax to a line with voice mail service

Voice mail services from your phone company conflict with faxing. When the voice mail service answers the line, the call is rerouted to the phone company and off your line. To use a voice mail service, you must do one of the following:
  • Use a distinctive ringing service from the phone company. Refer to the Distinctive ringing service setup section for more information about distinctive ringing.
  • If distinctive ringing is not available or undesired, contact your phone company for alternatives. If no alternative is available, faxes must be answered manually. Refer to the Receiving faxes manually section below for more information.

Connecting to a PBX phone system or an ISDN line

If your telephone line has a PBX system, make sure you dial the number for an outside line before dialing the fax number. When setting speed dials, use the Redial Pause button to insert a pause between the number for the outside line and the number being dialed.
NOTE:Many digital PBX systems include a call-waiting tone that is factory-set to "on." This call-waiting tone will interfere with any fax transmission, and you will not be able to send or receive faxes with your fax. Refer to your digital PBX system documentation for instructions on how to turn off the call-waiting tone.
If you are using either a PBX or an ISDN converter, make sure the fax is connected to the port that is designated for fax and phone use. Some ISDN systems allow you to configure the ports for specific phone equipment - for example, you might have assigned one for telephone and Group 3 fax and another for multiple purposes.
NOTE:If you have problems when connected to the fax/phone port of your ISDN converter, try using the port designated for multiple purposes (usually labeled "multi-combi" or something similar).

Receiving faxes manually

To receive faxes manually, follow the steps below.
  1. Answer the phone like you normally would a telephone call.
    If the incoming call is from a fax machine, you will hear beeps or fax tones.
  2. Press either Start Black or Start Color to begin receiving the fax.
  3. Hang up the phone.
