Xerox 5855 only holding 3 jobs

I have a Xerox 5855 which will only hold 2 or 3 jobs at a time.

I can see jobs queing up in the print queue but not getting to the printer. Only once a job is released from the printer will it leave the queue and sit in the held queue and so on and so forth.

I have a number of these devices in the business and only one is having this issue.

Printer is network on a 2008 server.

Firmware is most recent
