Pitch modes and throughput performance:
The printing
system can operate in several different
pitch modes
: 3, 4, 5,
6, and 7. The following table shows the minimum and
maximum boundary values for each pitch mode and the
default paper sizes that can be specified with the TMODE
parameter. The table shows these default scan values in
inches (IN), centimeters (CM), DOTS, and XDOTS (dots at
600 dpi), along with their associated print speeds in pages
per minute (ppm).
– In 7 pitch mode (the normal pitch mode for printing), the
printer can process paper from 8 inches by 10 inches to
9.01 inches by 14.33 inches or 203 by 254 to 229 by 364
mm, in long-edge feed mode. This means the sheet is fed
into the paper path with its long edge first.
In this pitch mode, the printer prints with full productivity at
180 pages per minute, with seven page images per
photoreceptor revolution.
– For papers whose width ranges from 9.01 inches to 15.31
inches, the printer prints with slightly reduced productivity.
The reason for this is that for papers in this width range,
the normal image area extends into the interimage zone
that is normally used for xerographic process controls. In
order to maintain the best productivity possible,
xerographic process controls are temporarily suspended.
Periodically, the system induces about 14 skipped
“images” in order to perform a xerographic process
control check and to ensure that the highest print quality is
maintained. The printer then resumes printing at full
productivity.
