Faxes are not printing on the product.
Cause Solution
Incoming call may be a voice call. Incoming voice calls usually show up in the call report as a
Communication Error (17) As these are voice calls and not a
fax error, no action is needed to be taken. Ensure that those
calling you have a voice number that is different from the fax
number.
The incoming fax was interrupted. Verify that the fax telephone line does not have an activated
call-waiting feature. A call-waiting notice can interrupt a fax
call in progress, which causes a communication error.

Error codes
If a fax problem occurs which prevents or interrupts sending or receiving of a fax, an error code is
generated that will 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 three reports to obtain
the error code. A detailed description for some error codes and the appropriate action can be found at
www.hp.com by searching for your product name.
Fax error messages
When an analog fax is sent or received on an HP LaserJet product, any errors that occur during the
fax process will be displayed on the product control panel and entered into the fax reports. Fax errors
can occur for many reasons and often they are due to interruptions or noise on the telephone
connection. Any error that takes place during the fax process regardless of where it originates will be
displayed by the product.
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 Administration > Information and
Administration > Troubleshooting menus). The numeric code is 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 Fax Failed: Communication 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. 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 Fail Busy
