Solve fax problems
General fax troubleshooting
Verify the following information before troubleshooting fax problems.
●
Is the fax set up correctly?
◦
Make sure that the fax cord that came with the product is being used. This cord has been
tested and meets the product specifications.
◦
Make sure that the fax cord is installed in the correct port. The fax cord must be plugged into
the line port.
●
What type of telephone line is being used?
◦
Dedicated telephone line: a unique telephone line that is assigned to receive or send a fax.
The fax cord must be plugged into the line port.
◦
Shared telephone line: a telephone line that receives or sends voice calls and faxes. A single,
shared telephone line can perform only one function at a time. A fax cannot be sent while
someone is talking on the telephone or while a computer is connecting to the Internet.
◦
Roll-over lines: a telephone system feature that allows an incoming call to be forwarded to
the next available telephone line (used with multiple-telephone-line systems). Try attaching
the device to the first incoming telephone line. The product will answer the telephone after it
rings the number of times that is specified in the product rings-to-answer setting.
◦
PBX system: a business-environment telephone system. Standard home telephones and the
product use an analog telephone signal. Some PBX systems are digital and might be
incompatible with standard telephones and with products such as the HP LaserJet M1319f.
◦
Distinctive ring service: a telephone system feature that can allocate two telephone
numbers to one physical line and then assign a distinctive ring pattern to each number. Make
sure that the device is set to respond to the correct distinctive ring pattern that the telephone
service provider assigned to the fax number. This service is not available in all countries/
regions. Make sure that the telephone company provides this service before changing the
setting.
●
Is a telephone-line splitting device installed?
◦
A telephone-line splitter is a device that splits two or more telephone lines from the same jack.
Not all splitters are compatible with the product, and not all countries/regions support the use
of splitters.
Parallel splitters (also called T-splitters) split a single line into two phone jacks so that two
devices can share the same line. Line 1/Line 2 splitters provide two unique telephone line
outlets from a single jack with two unique telephone numbers (two telephone lines are
connected to a single jack). A Line 1/Line 2 splitter must be used if both a fax line and a voice
line share the same jack.
NOTE: Hewlett-Packard does not recommend using a parallel splitter (T-splitter) with the
product because it might degrade the quality of the telephone signal. If a second device must
be attached to the telephone line in addition to the product, plug the second device into the
telephone port on the product (the port on the back that is marked with a telephone icon).
