Use the control panel service menu to choose T.30 Protocol Trace and then select At the end of each call. Configure another fax machine, preferably another HP LaserJet 3100 or 3150 product, to the same (or similar) settings.
Send a fax from the product or receive a fax to the product from the other fax machine. The fax trace report prints after the fax prints.
Explanations of some of the report’s column heading follow:
●Start time is the time the fax begins. Match it with the fax log of errors.
●Type is the type of fax activity, send or receive.
●Mode is the transmission mode. If it begins with “EC,” error correction was turned on. The set of three numbers is the BAUD rate divided by 100. For example, “EC144” in the mode column means that error correction was on and the transmission speed was 14,400 bps.
●Status explains the status of the fax:
•“Completed” means that the fax was successful.
•“Pending” faxes are in memory or are printing.
•Error numbers and their meanings appear in the user guide.
