Do not change this setting.
When "1" is selected, a line error mark is printed
on the printout if a line error occurs during
reception.
This is a fault-finding aid. The LCD shows the key
parameters (see below). 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.
If system switch 09 bit 6 is at "1", the list is only
printed if there was an error during the
communication.
Do not change the setting.
COMMENTS
Do not change these settings.
With this setting on, the machine resets itself
automatically if a transmission stalls and fails to
complete the job.
Do not change these settings.
