. Configure another fax
machine, preferably another HP LaserJet 3100 or 3150 product, to

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.
Translating the fax trace report

report contains information about the product’s interpretation of the
problem.
Read the time sequences, looking for abnormal activity on the fax
trace report. See Table 20, Fax phase sequence, and Table 21,
Appropriate responses, to separate normal from abnormal activity.
Fax abbreviations appear in Table 22.
