•
Make sure you have correctly connected the HP Officejet to the
telephone wall jack, and correctly connected any additional
equipment and services that share the phone line with your
HP Officejet.
•
Using a telephone line splitter can cause faxing problems. (A
splitter is two-cord connector that plugs into a wall jack.) Try
removing the splitter and connecting the HP Officejet directly to the
telephone wall jack.
•
Check that the telephone wall jack has a working telephone line by
plugging in a phone and checking for a dial tone.
•
Telephone lines with poor sound quality (noise) can cause faxing
problems. Check the sound quality of the telephone line by
plugging a phone into the wall jack and listening for static or other
noise. If you hear noise, turn off the Error Correction Mode (ECM)
feature on your HP Officejet and try faxing again. For information,
see
use error correction mode
on page 65. Also contact your
phone company to report the noise problem on your line.
•
Other equipment using the same telephone line as the HP Officejet
might be in use. For example, you cannot use your HP Officejet for
faxing if an extension phone is off-hook, or if you are using your PC
modem to e-mail or access the Internet.
•
If you are using a digital subscriber line (DSL), make sure that you
have a DSL filter connected or you will not be able to fax
successfully. Obtain a DSL filter from your DSL provider. The DSL
filter removes the digital signal that blocks your HP Officejet from
communicating properly with the telephone line.
For information on how to connect the DSL filter, see
faxing from a
DSL line
on page 131.
•
Check for error messages on the front panel display of your
HP Officejet. Until a product error condition is resolved, you will not
be able to send or receive faxes. For information on resolving error
conditions, see the
hp officejet 4200 series
troubleshooting section
in the onscreen
hp image zone help
that came with your software.
•
If you are using either a PBX or an ISDN converter, make sure the
HP Officejet is connected to the port that is designated for fax and
phone use.
Note that 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. If you continue to have problems when connected to the
fax/phone port, try using the port designated for multiple purposes
(might be labeled “multi-combi” or something similar).
