Hello, I have a question about the MFP Xerox WC 4150. For a couple of months worked fine, but in november arised a problem. When I print more than a job (i.e. 68 unique pdf of one page each) the printer stops after the 60th, and in the printing queue remains some job saying "Completed" but it's not possible to delete them. So I switch off the printer and wait some time to be able to print again. I called Xerox assistance, they replaced first the hard disk, then motherboard, ram and network controller. Now the printer stop even after 10 Excel file's printed, apparently randomly.
There's not any error reporting. It seems that the printer is somewhat overloaded, and resumes printing after she has disposed of the jobs.
But I printed only one sheet at a time.... normal spreadsheet files.
I upgraded bios to version 10.100.46.000 but it don't resolve the problem...
What can I do? Any suggestion is very appreciated!
There's some hidden menu in the web interface?
I need help :-\

Thanx for the support.
