HP CC487-91209 Fax Manual page 134

If the fax process is interrupted or an error occurs during a fax transmission or reception, a two part
status/error description is generated by the fax subsystem on the product. Normal or successful faxes
also generate messages indicating success. The message information consists of a text description
and a numeric code (a few messages don't include numeric codes). Only the text part of the message
will be displayed on the product control panel; however, both the text message and numeric code will
be listed in the Fax Activity Report, Fax Call Report, and the Fax T.30 Trace (these fax reports can be
printed out individually from the product control panel – under the
Reports and
shown in parentheses after the text part of the message in the reports. For example, if a
communication error occurred, the control panel display would show
Error. The same error would be shown in the Result field in the Fax Activity Report as Communication
Error (17). For this example, the numeric code associated with this communication error is '17'.
The numeric code is generated by the fax modem. Usually a numeric code of (0) indicates a normal
modem response. Some messages will always display a numeric code of (0), whereas other
messages can have a range of numeric codes depending on the circumstances, and a few messages
will have no numeric code. Usually a numeric code of (0) indicates an error was not associated with
the fax modem, but occurred in another part of the fax subsystem or other product subsystem such
as the printing subsystem. Non-zero error codes give further detail into the particular action or
process that the modem is executing, and they don't necessarily indicate that there is a problem with
the modem.
In the tables that follow, the fax messages with the most common number codes are given with
recommended corrective action. Several messages that are normal or indicate a normal event are
also included in tables. For example, if a fax was not able to be sent to a busy number, a
message will be shown. Nothing is wrong with the fax subsystem; the message indicates the fax was
not completed due to a busy telephone number at the receiving end.
Persistent error messages with numeric codes different than those listed here require assistance of
customer support. A more detailed listing of the last fax call can be printed out before contacting
customer support to help identify the problem. The detailed fax listing is called a Fax T.30 Trace and
can be printed for the last fax, or it can be set to print whenever a fax error occurs. To print or
configure the Fax T.30 Trace, touch Administration, Troubleshooting, and then
can then print the report for the last fax or configure when to print the T.30 trace.
