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
