Xerox 4505/4505ps manual For the 4510/4510ps printers, Auto Job End is On

For the 4510/4510ps printers:

When print jobs are pending on all five ports (parallel, serial, and the network interface ports), the port polling sequence is:

1Parallel

2Serial

3Ethernet

4Token Ring

5Back to Parallel

LocalTalk is not a part of this sequence. When a print job is detected on the LocalTalk port, the print job is put in the queue immediately after any current job finishes.

Note

Except for those on the LocalTalk interface, print jobs are processed in the sequence in which they are received by the printer. As soon as one print job has finished, the printer continues polling until it finds another port that has received data.

If a print job is incomplete, the printer waits until the port is inactive for the Port Timeout period. After that, the printer ends the incomplete job and continues polling the ports when either:

•Auto Job End is On

or

•Another print job is received on a port

Therefore, the printer does not excessively service one particular port.
