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 HP LaserJet Analog Fax Accessory 500. 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. Persistent error messages with numeric codes different than those listed here require assistance of customer support. Print a Fax T.30 Trace report before contacting customer support to help identify the problem. This report contains details of the last fax call. 1. From the Home screen on the product control panel, scroll to and touch the Administration button. 2. Open the following menus: ● Troubleshooting ● Fax ● Fax T.30 Trace 3. Select the Print T.30 Report option to print the report. ENWW Solve fax problems 291
