Got a call for a loud squeaking noise, checked everywhere - etc, no noise upon arrival. 2600 more clicks on drum unit. I could hear a faint squeak from the center left side, ran test prints 150 pages, nothing like customer describes. Any clues ? thanks, wiley

Will almost have to be either the Toner Cartridge or the LSU...Haven't had many LSU issues on that model yet so I'd lean toward the toner. -Cope
