HP Officejet J5740 All-in-One Printer - Manual (Page 33)

Case C: Set up the HP All-in-One 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
HP All-in-One 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 will interfere with any fax transmission, and you
will not be able to send or receive faxes with the HP All-in-One. 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
HP All-in-One. 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.
