5-26 XEROX DOCUPRINT 180 LASER PRINTING SYSTEM PRODUCT GUIDE
Switching paper size and feed modes
The Xerox DocuPrint 180 LPS system operates in a multiple-pitch
print mode: 8 pitch to 3 pitch.
The multi-pitch feature allows your Xerox DocuPrint 180 LPS to
adjust the pitch mode according to the width of the paper you are
using. Table 5-15 shows the relation between the pitch mode, the
maximum width of the paper being fed in a long edge feed mode, and
the page per minute (PPM) rate. Long edge feed mode means the
sheet is fed into the paper path with its long edge first.
For papers whose widths range from 8.66 to 9 inches, the Xerox
DocuPrint 180 prints with slightly reduced productivity at 180 pages
per minute, with seven-page images per photoreceptor revolution.
Productivity is slightly reduced because in order to maintain print
speed for papers of this size, the system must temporarily suspend
xerographic print quality checks. The Xerox DocuPrint 180 maintains
the highest print quality by periodically reducing printer output to
perform xerographic print quality checks. After a print quality check,
the system automatically resumes printing at full productivity.
