Fax Protocol Report
The Protocol Report provides transmission results, timing, and communications activity infor-
mation about each Fax transmission. Accessed from the System -> Information -> Trouble-
shooting -> FAX Problems menu, the Protocol Report provides Job Details similar to the
Transmission Report, and a detailed log of the communications activity between devices. Use
this report to diagnose possible communications errors between machines.
Table 1 lists the most common commands exchanged between Fax machines during a typical
transfer of data. When reviewing the Protocol Report, trace the exchange of commands to
identify irregularities. Commands in parentheses (_) may or may not appear in the log.
Fax Transmission Report
The Transmission Report provides transmission status and activity information about each Fax
transmission. Generation of this report is optional and is in an Error Only state by default. Use
the menus: System -> Job Defaults Setup -> Fax Defaults Setup -> Fax Send Setup to change
the Error Only default. Also by default, for the 8560MFP, the Transmission Report includes a
reduced image of the document scanned for faxing. Result codes appear in the Results box of
the Job Details section at the bottom of the page. The results format is <code><speed>. Where
code is one of the codes listed in Table 2. Speed is the transmission baud rate (i.e. 9600). Typ-
ically, the results are CP<speed> for a completed Fax. Fax failures (FA) may omit the speed if
the system was unable to start the connection. The job termination results (FA, TU, TS) count
as errors for the purpose of printing a Transmission Report.
In addition to the Results codes, the Job Details section includes Mode and Job Type codes.
Definitions of all these codes appears on each report.
