COMMENTS
If there are more consecutive error lines in the
received page than the threshold, the machine will
send a negative response.
The Low and High threshold values depend on the
sub-scan resolution, and are as follows.
Resolution Standard
Low settings 3
High settings 6
If the error line ratio of a page exceeds the acceptable
ratio, RTN will be sent to the other end.
0: Pages received with errors are not printed.
0: The next page will be sent even if RTN or PIN is
received.
1: The machine will send DCN and hang up if it
receives RTN or PIN.
This bit is ignored for memory transmissions or if ECM
is being used.
Do not change the settings.
