How do I set up HP printers in digital phone environments?
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, ISDN, or VoIP), you might need to use digital-to-analog filters or
converters when setting up the printer for faxing.
Note: The printer might not be compatible with all digital service lines or providers in all digital environments
or with all digital-to-analog converters. Contact your phone company to determine which setup options are
best for you.
Note: If you are setting up ring pattern detection in a PBX phone system that has different ring patterns for
internal and external calls, make sure you dial the fax number of your printer using an external number when
recording the ring pattern.
4. Test fax setup
The fax test does the following:
• Tests the fax hardware
• Verifies the correct type of phone cord is connected to the printer
• Checks that the phone cord is plugged into the correct port
• Checks for a dial tone
• Checks for an active phone line
• Tests the status of your phone line connection
To run the fax test:
a. On the printer control panel display, touch Fax, touch and slide your finger across the screen, and then
touch Setup.
b. Touch Tools, and then touch Run Fax Test. If the test fails, review the report for information on how to fix
the problem, make the suggested changes, and run the test again.
If you still have problems using fax after successfully completing the fax test, visit www.support.hp.com.
