Automatic PFS suppression
Automatic PFS suppression uses the format of a well-formed XES job to
automatically begin and end PFS suppression.
In the XES command set, there are four different commands that can be
used to begin a job. These commands indicate to the printer that a new
print job has begun. These commands are listed below:
s+PdPrint Job
s+QdPrint Job (mixed orientation)
s+MdMerge Page Load
s+NdForm Load
where d indicates a line ending.
When Auto PFS suppression is active, the OPTIMA automatically begins
PFS suppression mode when it sees one of these XES commands in the
data stream. Auto PFS suppression is ended when the OPTIMA sees the
XES job end command in the data stream:
s+XdReset
These job begin and end commands are part of the XES command set.
Although these are the commands normally used to begin and end XES
mode print jobs, Xerox printers are forgiving if they are not in the data
stream.
In order for Auto PFS suppression to work, the XES job must be
started and ended with these commands.
Automatic Form Feed Suppression
Auto FF suppression is initiated in the same way as Auto PFS suppression,
although there is a separate configuration option to select whether or not
this occurs.
Because Auto FF suppression is particularly useful for form download
jobs, it is possible to configure FF suppression to be initiated by
s+Md or s+Nd (both of which initiate a form-based job) but not
s+Pd or s+Qd. This is in addition to the standard Auto FF
suppression mode that is initiated by any of the four commands.
