DEFINING CLUSTERS
5-4 XEROX DOCUPRINT 180 LPS PDL REFERENCE
Stockset applications
Each page has a particular stockset and a particular cluster
associated with it. The cluster is always verified because it
determines from which trays a page may feed. The stockset is
verified only if the current page calls a different stockset than the
previous page called.
Stockset changes require the cluster checks described in table 5-1.
A cluster without these errors has an “in use” status, that is, it has
trays and is in the stockset last called by the job. Any one of these
errors in any clusters in the stockset gives “in error” status to the
stockset.
As jobs print, the output task uses the application's specified cluster
to choose a tray for each page. Occasionally it provides a cluster
status display. If an operator enters FEED commands that override
the data, for example, the FEED=DJDE, then the printer cycles down
and displays:
OS2289 Warning: Current FEED command overrides data
FEED= value.
Mixing applications
When a site runs simple and OTEXT applications with stockset
applications, the LPS executes two additional stockset checks to
help ensure the correct paper is loaded. They are as follows:
• If a report has no stockset information, then a stockset change
is assumed.
• A stockset change is assumed at each job boundary,
regardless of the stocksets used.
To run a simple or OTEXT application correctly after a stockset
application while avoiding printer cycle downs, ensure that the
current trays are always in the MAIN and AUX clusters.
A stockset application run after a simple or OTEXT application
always causes a printer cycle down, allowing you to load the correct
trays (if necessary) before continuing.
