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.
TIA
