Fax and digital phone services
Many telephone companies provide their customers with digital phone services, such as the following:
● DSL: A Digital subscriber line (DSL) service through your telephone company. (DSL might be called ADSL
in your country/region.)
● PBX: A private branch exchange (PBX) phone system.
● ISDN: An integrated services digital network (ISDN) system.
● VoIP: A low-cost phone service that allows you to send and receive faxes with your printer by using the
Internet. This method is called Fax on Voice over Internet Protocol (VoIP).
For more information, see
Fax on Voice over Internet Protocol .
HP printers are designed specifically for use with traditional analog phone services. If you are in a digital
phone environment (such as DSL/ADSL, PBX, or ISDN), you might need to use digital-to-analog filters or
converters when setting up the printer for faxing.
NOTE: HP does not guarantee that the printer will be compatible with all digital service lines or providers, in
all digital environments, or with all digital-to-analog converters. It is always recommended that you discuss
with the telephone company directly for the correct setup options based on their line services provided.
Fax on Voice over Internet Protocol
You might be able to subscribe to a low cost phone service that allows you to send and receive faxes with your
printer by using the Internet. This method is called Fax on Voice over Internet Protocol (VoIP).
The following are indications you probably use a VoIP service.
● Dial a special access code along with the fax number.
● Have an IP converter box that connects to the Internet and provides analog phone ports for the fax
connection.
NOTE: You can only send and receive faxes by connecting a phone cord to the port labeled "1-LINE" on the
printer. This means that your connection to the Internet must be done either through a converter box (which
supplies regular analog phone jacks for fax connections) or your telephone company.
TIP: Support for traditional fax transmission over any Internet protocol telephone systems are often
limited. If you experience problems faxing, try using a slower fax speed or disabling the fax error-correction
mode (ECM). However, if you turn off ECM, you cannot send and receive color faxes.
If you have questions about Internet faxing, contact your Internet faxing services support department or your
local service provider for further assistance.
Use reports
You can set up the printer to print error reports and confirmation reports automatically for each fax you send
and receive. You can also manually print system reports as required; these reports provide useful system
information about the printer.
By default, the printer is set to print a report only if there is a problem sending or receiving a fax. A
confirmation message that indicates whether a fax was successfully sent appears briefly on the control panel
display after each transaction.
NOTE: If the reports are not legible, you can check the estimated ink levels from the control panel or the HP
software. For more information, see Check the estimated ink levels .
