Xerox 4510 Manuel D’Utilisation

C-3

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:

1 Parallel

2 Serial

3 Ethernet

4 Token Ring

5 Back 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.

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

•

Another print job is received on a port

Therefore, the printer does not excessively service one

particular port.
