Xerox 4510/4510ps manual For the 4505/4505ps printers

The 4505/4505ps printers provide a parallel port, serial port, and one additional network interface port option, all of which may be active at the same time.

The 4510/4510ps printers provide a parallel port, serial port, and three additional network interface port options, all of which may be active at the same time.

To coordinate automatic switching among the ports, the printer monitors the parallel, serial, and network interface ports for incoming data. When a print job is detected on one port, the printer sends a busy signal to the other ports and queues the print job into memory for processing. This is called port polling. Note that while all ports may be simultaneously active, only one port at a time is able to receive a print job.

For the 4505/4505ps printers:

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

1Parallel

2Serial

3Network

4Back to Parallel
