Printer Controller Service Mode
bit 7 Letterhead mode printing
Routes all pages through the duplex unit.
If this is disabled, simplex pages or the last page of an odd-paged duplex
job, are not routed through the duplex unit. This could result in problems
with letterhead/pre-printed pages.
Only affects pages specified as Letterhead paper.
1001 Bit Switch
007 Bit Switch 7
bit 0 Print path
If enabled, simplex pages (in mixed simplex/duplex PS/PCL5 jobs only)
and the last page of an odd paged duplex job (PS, PCL5, PCL6), are
always routed through the duplex unit. Not having to switch paper paths
increases the print speed slightly.
