Paper width and throughput speed (LCDS printing only)
The width of the paper you use for your LCDS print job is directly
related to the rate at which the printer can print the job. The rate
at which a job prints is called the “throughput speed” and is
measured in pages per minute (ppm).
NOTE: “Pages per minute” actually means “impressions per
minute,” referring to one side of a printed sheet.
A pitch is the amount time the printer takes to image a page on
the photoreceptor belt. The term “pitch mode” refers to the
number of pitches that can occur during one complete
photoreceptor revolution. The pitch mode in which a specific job
prints is based on the paper size used for that job.
The following tables list the pitch mode boundary values, paper
widths, and related printing speeds for the system. Notice that
the shorter the paper width, the higher the pitch mode and the
faster the throughput speed (higher page per minute rate).
