Problem Cause Solution
Outgoing fax calls keep dialing. The fax accessory automatically redials
a fax number if the
Redial On Busy
option is on or if the Redial On No
Answer option is on.
This is normal operation. If you do not
want the fax to retry, set the
Redial On
Busy option to 0, set the Redial On No
Answer option to 0, and set the Redial
on error option to 0.
Faxes you send are not arriving at the
receiving fax machine. The receiving fax machine might be
turned off or might have an error
condition, such as being out of paper. Ask the recipient to make sure the fax
machine is turned on and ready to
receive faxes.
A fax might be in memory because it is
waiting to redial a busy number, or
there are other jobs ahead of it waiting
to be sent. If a fax job is in memory for either of
these reasons, an entry for the job
displays in the fax log. Print the fax
activity log, and check the Result
column for jobs with a Pending
designation.
Fax error codes
If a fax problem occurs which prevents or interrupts fax transmission, an error code is generated that
can help in determining the cause of the problem. Error codes show up in the fax activity log, the fax
call report, and the T.30 Protocol Trace. Print one of these reports to obtain the error code. A detailed
description of the error codes and the appropriate action is available at www.hp.com . Search for

Fax error messages on the product control panel
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 do not include numeric codes). Only the text part of the message is
displayed on the product control panel; however, both the text message and numeric code are listed in
the Fax Activity Report, Fax Call Report, and the Fax T.30 Trace. The numeric code is shown in
parentheses after the text part of the message in the reports.
The fax modem generates the numeric code. Usually a numeric code of (0) indicates a normal modem
response. Some messages always display a numeric code of (0), other messages can have a range of
numeric codes, and a few messages 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 system or other
product sytem such as the printing system. Non-zero error codes give further detail into the particular
action or process that the modem is executing, and they do not necessarily indicate that there is a
problem with the modem.
