Job Control; Job Control Sequence - Xerox DocuColor 12/DCCS50 Service Manual

Job Control

The User Interface (UI) PWBA provides overall job control through communications with the
IOT CPU PWBA. The TR0 signal controls the timing of the job control sequence.

Job Control Sequence

This machine is capable of a large variety of job control sequences, depending on how it is
being used:
• Is the task a print job from the DFE or a copy job from the Platen?
• Is the output sheet size larger than 8.5" X 11" and A4?
• Is the output simplex or duplex?
• Does the output include color?
• Does the unit include a DADF? Is its automatic feed function being used?
• Does the unit include an output Mailbox/Sorter option?
• Does the unit include an OCT option?
These factors can be mixed in any combination.
Figure 1 shows the job control sequence when using the machine as a Printer accessed from
the DFE. This figure shows decisions for:
• Small prints (8.5" x 11"/A4 and smaller) vs. larger sheets
• Color vs. black and white images. Note that this decision is made on a sheet by sheet
basis, not for the entire print job
• Simplex vs. duplex operation
This figure ignores Mailbox/Sorter and OCT operation.
Figure 2 shows the job control sequence shows decisions for print size and color/B&W opera-
tion. This figure ignores the simplex/duplex output decision, Mailbox/Sorter operation and OCT
operation.
Figure 3 shows the job control sequence with originals placed in the DADF. Like
figure shows the job control sequence making decisions for print size and color/B&W opera-
tion. However, it ignores the simplex/duplex output decision, Mailbox/Sorter operation and
OCT operation.
