HP Enterprise M551DN dirty background print out

We have a M551DN color printer with the weirdest problem that I've seen:
1. If I test the printer itself to print its demo page, it prints out perfect color and clean.
2. If the customer send a print job thru the network, the print out has dirty back ground with magenta and sometimes cyan dot over the page.

Has anyone here seen this problem before, please advise.
