ADJUSTING PRINT QUALITY AND SPEED
XEROX DOCUPRINT 96/4635/180 NPS TROUBLESHOOTING GUIDE 7-5
Calculating throughput
For measuring performance, note the start time, stop time,
decomposition time, elapsed time, and pages of the job being
measured:
• The start time is the time that the sequencer began to
decompose the job (translate the PostScript).
• The stop time is the time the last page was printed.
• The decomposition time is the time (in seconds) spent working
on the job. The decomposition time can be increased by factors
such as use of highlight color, images that compress poorly,
duplexing, and job size. See the Guide to Using Page
