Advancing Forms Using the NPRO and NPRO Page Functions
NPRO (NonProcess RunOut) moves forms forward through the forms path.
vIn simplex mode, NPRO moves the forms forward to the stacker area. Forms are
fused as they move toward the stacker area.
vIn duplex mode, NPRO moves forms forward through the forms path of Printer
1, the Buffer/Flipper Unit, and Printer 2. Pages that wereprinted on Printer 1
are printed on Printer 2, and Printer 1 processes blank pages. After all pages are
printed on Printer 2, the forms move forward through the forms path of both
printers without printing until all pages printed on Printer 2 are in the stacker
area. Pages already printed on Printer 1 at the start of this procedure and pages
printed on Printer 2 during this procedure are fused as they move toward their
respective stacker areas.
The distance NPRO moves forms depends on your printer configuration. There is a
fixed NPRO length that you can increase with two differentconfiguration items.
Youmay want to increase the fixed length, for example, if you are using a
postprocessing device.
Two configuration parameters let you extend the NPRO length when END OF FORMS
078A is not indicated:
vThe “Pre/postprocessor Extended NPRO” parameter in the Configure
Pre/postprocessor procedure. See “Configuring Preprocessing/Postprocessing
Devices/Interfaces”on page 241 and the “Extended NPRO” table item on page
“Extended NPRO”on page 243 for more information.
vThe “NPRO Length” parameter in the Configure Printer procedure. See
“Configuring the Printer”on page 219 and the “NPRO Length” table item on
page “NPRO Length”on page 223 for more information.
Note: If you set the “Pre/postprocessor Extended NPRO” item of an enabled
pre/postprocessor to a non-zero value, it takes precedence over the
Configure Printer “NPRO Length” item, regardless of the particular values
specified.
NPRO Procedure
NPRO is usable only under certain conditions, which balance safety considerations
with operator convenience.
