Dell printer goes offline(server connection) after second print job. Although the printer's display says it is ready. If you turn off then on the printer you can send one job and goes back offline(server connection) on the next print job.

We have multiple Dell 2330dn printers installed through a print server, only one of the printers is experiencing this problem. 
Two different users.
Two different machines.
Two different operating systems (win7 and Vista).

The computers have been reset.
Dell printers have web interface if this helps (through IP address).

Thanks for any help!
