COMMENTS
This bit determines the data type to be printed on the
TCR (Journal) when technical data printout is enabled
by bit 2 above.
If this bit is 1, a mark will be printed on the left edge of
the page at any place where a line error occured in the
data. Such errors are caused by a noisy line, for
example.
This is a fault-finding aid. The LCD shows the key
parameters (see the next 2 pages). This is normally
disabled because it cancels the CSI display for the user.
Be sure to reset this bit to 0 after testing.
This is only used for communication troubleshooting. It
shows the content of the transmitted facsimile protocol
signals. Always reset this bit to 0 after finishing testing.
Change this bit to 1 if you want to have a protocol dump
list of the last communication only.
