XEROX DOCUPRINT 180 LPS PDL REFERENCE 6- 93
— Estimating the time needed to run your print jobs for
scheduling purposes. To better understand the potential
value of specifying pitch modes in your JSLs, consider
these hypothetical situations:
– Your finishing device folds and binds your printed
output but accepts pages at a considerably slower ra te
than the 180 pages-per-minute capability of your
DocuPrint 180 laser printing system. You may want to
slow down the rate at which your DocuPrint 180 LPS
sends printed sheets to this device by specifying a 4-
pitch mode. Assuming that your application calls for
8.5 by 11-inch paper, you could use 5-pitch mode, but
by selecting 4-pitch, you reduce the pages-per-minute
(ppm) from 180 to 77, which better matches your
finishing device's capabilities and reduces the
potential for paper jams.
– Your application uses four paper sizes, ranging from 8
by 11-inches for the first few pages to 11 by 17-inches
for the last several pages. Each time your printer
detects a different paper size, it adjusts to
accommodate the new paper size, thus noticeably
reducing throughput time. By specifying a large
enough pitch mode to accommodate all the paper
sizes in your application, in this case, 3-pitch mode,
the entire job runs at the maximum possible
throughput speed because paper size adjustments are
limited. Keep in mind that you may select a lower pitch
mode (allowing a greater scan value) for smaller size
paper but that you would not want to select a pitch
mode too small to accommodate a larger paper size.
– You want to estimate how many applications you
could run on a particular shift. But, given the size and
complexity of your applications, you are uncertain as
to how to plan. By looking at the paper sizes, and
thereby, the pitch modes required by each application,
and the number of pages in each application, a nd by
associating these with the ppms provided in tables 6-
10 and 6-11, you can then roughly estimate the length
of time each application requires for printing.
