hp laserjet 4000t

[spuentes]

I am having problems with my hp printer laserjet 4000t. It's on a network, so there are aobut 20 people printing. It won't print, and it often shows 79.00 error. Please help.

For trouble shooting 79 and 80 errors you want to determine if external I/O devices are the cause or if it is the formatter. Remove all external I/O devices (JetDirect, memory, etc.) and see if problem persists. If not, replace the formatter.
