ADJUSTING PRINT QUALITY AND PERFORMANCE

6-4

XEROX DOCUPRINT 92C NPS TROUBLESHOOTING GUIDE

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 

Description Languages

 for more details about factors affecting 

performance.

•

The elapsed time, equal to the stop time minus the start time, is 
the total amount of time DocuPrint spent printing the job. The 
elapsed time includes delays for warm-up time, paper loading, 
jam clearing, print quality adjustments and the start-up latency 
associated with the first job in a set of jobs.

•

The “pages” number represents the number of images printed, 
(not the number of sheets printed when running a duplex job).

To make a meaningful measurement of performance, obtain the 
measurements while the printer is running a block of jobs. Because 
start and stop times tend to overlap between jobs in a block, the only 
way to obtain a measurement using the start and stop times is to use 
the start time when the printer first powers up to print a block of jobs, 
then subtract that start time from the stop time when the printer 
powers down as shown in this procedure:

1. Enter 

Stop Printing

 at the Printer Controller.

2. Enter 

Set Option ForceReport False

 and 

Set Option 

UseTitlePage False

. This avoids extra pages in the output that 

are not included in the pages reported in the sequencer log.

3. Send a series of jobs to the DocuPrint.

4. Use the List Documents command to determine that the jobs 

have passed the prescanner and have a Pending status.

5. Enter 

Start Printing
