9.3 Compatibility with Mechanical Page Counters
The PrintServer printers have mechanical page counters.
The mechanical page counter is different from the counter accessible through
the PostScript pagecount operator.
• The mechanical page counter counts all the sheets printed since the print
engine was built.
• The PostScript page counter counts the number of sheets printed by the
controller.
Under normal use, the totals of both counters increase at a similar rate, but
there can be a significant difference between them. Print engine test pages,
initiated with the test button on the printer, are recorded on the mechanical
counter but not on the PostScript counter. Also, replacing components can
affect the counters. For example, replacing the nonvolatile memory of the
controller resets the PostScript counter, but it does not affect the mechanical
counter.
Because the counters record different events, they should be used for different
purposes:
• Use the PostScript counter to determine the number of sheets printed
within a PostScript program.
• Use the mechanical counter to track print engine use.
