Overview
Table 1-9 Throughput data for DP180
Each time a job requires a different paper size that changes
across a pitch boundary, the system performs a time-consuming
xerographic quality adjustment. When the printing speed of an
LCDS job appears to degrade due to the use of mixed stock sizes,
the following actions may improve the performance:
• You can optimize throughput by double clicking on a job in Job
Manager or double clicking on a queue in Queue Manager and
selecting Properties. The Output tab has a Mixed Stock Size
Job window where you can select Optimize throughput. You
must also enter the width of the widest paper in inches or
millimeters for the job.
• The job programmer may be able to improve the speed by
using the LCDS PDL command OUTPUT TMODE in the JSL
to run the print job in a lower pitch mode. Refer to the
OUTPUT TMODE parameter in the Xerox Document Services
Platform Using LCDS Print Description Language for
information on using this command.
• Similarly, if the system cycles down frequently because your
external finishing equipment has a slower throughput rate than
the printing system, the OUTPUT TMODE command can be
used to lower the pitch mode to match the speed of the
finishing equipment. This can improve overall throughput by
avoiding time-consuming cycle downs.
NOTE: Pitch mode changes are supported only for LCDS printing.
Paper size and pitch mode minimum and maximum
The illustrations in this section show the pitch modes in which you
can operate, with the smallest and largest size papers supported
by the printing system.
