Anyone out there had these made a loud noise very intermittently that sounds like it's coming from the toner/drum area? Have had a couple of these do it now on initial setup and one customer that says their's does it about once a week for 5 or 10 seconds and then goes away and runs perfectly until the next time.

Saw a few hits on here and Lexmark tech support for noise in the DF but nothing within the machine itself.

Thanks
