Understanding clusters
A cluster is a group of related feeder trays. The trays assigned to a
cluster usually contain the same size and type of paper. All trays
within a cluster are considered equal when the LPS identifies which
tray will feed a sheet of paper. This allows common stock to feed from
more than one tray.
Clusters are set up and named by the person who creates the job.
The cluster name consists of 1 to 6 alphanumeric characters,
beginning with an alphabetic character. The name can represent the
type of stock used in the job (for example, BLUE). The cluster
definition and name allow the LPS to locate the feeder trays with the
correct paper stock used for a specific job. Clusters allow you to use
more than one size of paper within a job and to use groups of trays
within a job as if they were only one tray.
Based on messages from the LPS, you load the correct stock into the
feeder trays and tell the LPS which stock is in which tray (refer to the
“Tray loading and clusters” section later in this chapter). The LPS
then selects the stock as required by the print job, selecting a feeder
tray for each page by checking the cluster name and paper size
associated with the page.
You can display the current clusters, override the preferred trays
recommended by the cluster, or choose a specific cluster or tray to
be used for feeding paper for a job. For additional information on
clusters, refer to the
Xerox DocuPrint 180 LPS Operations
Reference.
