This section provides troubleshooting procedures for Fax problems not
reported to the Control Panel as an error message. The printer provides
several built-in tools for troubleshooting Fax problems. As a first step, perform
these initial checks to isolate the problem.
Check these items first. Use a desk telephone and a second, known-good
phone line to test Fax line function.
Check that Fax is enabled and configured properly for the phone line.
Check the target Fax number. If the number is in memory, is it correct?
Call the target Fax number from a desk phone to confirm a Fax tone
response.
Use a desk phone to confirm a dial tone on the Fax line.
Check Fax line condition and connections.
Print a Protocol Report if reports aren't being printed.
If the Fax line, Fax number, and cabling are all functional, use these tools
to isolate the problem.
The primary tools for troubleshooting Fax problems are Tech mode tests and
the Protocol Report. Tech mode test results and the Protocol Report provide
valuable clues to the root cause of Fax errors.
Tech mode includes access to Fax transmission parameters and tests of the
system's Fax subsystem. Use the Data Setup menu to adjust Fax parameters
to match line capabilities. Use the Machine Test menu to test operation of the
system's Fax modem and system memory.
Clear All Memory resets all Fax parameters to factory-default values and
cancels or deletes all incoming and outgoing faxes. All customer programmed
data, such as the Individual and Group Speed Dial directories, are lost when a
Clear All Memory command is issued.
The Protocol Report provides a detailed log of the communications activity
between devices. Use this report to diagnose possible communications errors
between machines.
The following table lists the most common commands exchanged between
Fax machines during a typical data transfer. When reviewing the Protocol
Report, trace the exchange of commands to identify irregularities. Commands
in parentheses (_) may or may not appear in the report.
