Xerox 4.2 - Manual (Page 18)

If Enhanced RBS is in effect, DocuSP RIPs the job to
determine the resourced defined within the job data
before scheduling the job. If, after RIPping the job, the
controller determines that the job requires unavailable
resources, the job is marked Ineligible and a message
is generated detailing which resources are currently
unavailable. If a job specifies a greater quantity of an
available media than is present on a system, it prints
until the system runs out of that media; then the
operator is prompted to add the required media.
Additional PCL Paper Sources
In DocuSP 4.2, the common controller is extended to
support 21 more paper sources for PCL. Under
DocuSP 4.1, the PCL decomposer provided a total of 6
PCL paper sources, which does not meet the
capabilities of certain systems; for example, the Nuvera
product may have up to 12 physical feeds by allowing
customers to add external paper feeder modules. With
DocuSP 4.2, customers with systems that have more
than 6 trays can map a unique PCL paper source to
each of their trays.
Instructions for programming PCL paper sources are
included in the DocuSP Online Help.
