HARDWARE COMPONENTS
The LPS offers two output configurations: the dual stacker and
the stitcher/stacker. Each configuration has a paper transport
mechanism to allow paper handling. Each configuration can also
offset an output set approximately 0.5 inch from the previous
set.
Samples are delivered to a sample tray. Sample pages can
include printouts of information stored in the system, a duplicate
copy of the current output page, or a sample of the next page
the system will print. This sample print feature allows you to
examine job pages. When a sheet is delivered to the sample
tray, the system reprints the sample sheet and delivers it to the
active stacker tray, thus maintaining the integrity of the output
set.
Note: You should always route transparencies to the sample
output tray.
The 4050/4450/4650 LPS delivers output at a rate of up to 50
PPM, and the 4090 delivers output at a rate of up to 92 PPM for
the first copy of a report, depending on the processing features
you use and the density of the page. Subsequent copies of a
report do not require input processing time except when you
use copy-sensitive processing. The output rate increases for
subsequent copies when any of the following occurs:
• All required forms and fonts remain in memory for the
duration of the job.
• Entire job runs in either simplex or duplex mode.
• No copy-sensitive processing.
• System can hold the entire print file for the report on disk.
• No hardware errors or system recoveries occur.
• Graphic image size is three-quarters of a megabit or less on a
page-to-page basis.
When printing in duplex mode, printing throughput is reduced
when form and font memory cannot accommodate all the forms
and fonts used.
