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 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 over
Internet Protocol (FoIP).
You probably use a FoIP service (provided by your telephone company) when you:
• Dial a special access code along with the fax number, or
• 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. (For more information about changing the
fax speed, see
Set the fax speed. For more information about using ECM, see Send
a fax in Error Correction Mode.
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
Printer management
tools.
NOTE: Ink level alerts and indicators provide estimates for planning purposes only.
When you receive a low-ink alert, consider having a replacement cartridge available
to avoid possible printing delays. You do not need to replace the ink cartridges until
prompted to do so.
