ADJUSTING PRINT QUALITY AND SPEED
XEROX DOCUPRINT 4050/4090 NPS TROUBLESHOOTING GUIDE 6-7
In the example shown in this log, here is the calculation:
The start time was: 10:12:25 am
The stop time was: 10:23:31 am
(This gives an elapsed time of 11 minutes and 6 seconds, or 666
seconds)
PPM = 60 x 990/666 = 89.2 pages per minute
As you can see for the same job, the calculated throughput
approaches the maximum speed of the printer as the start-up latency
becomes less important and the calculation is closer to the actual
sustained throughput of the job.
