On startup, during the short warmup cycle, while printing, and while occasionally cycling hen left on but not being used, the machine makes a really loud clattering noise -- sounds like the rat-a-tat-tat of a toy machine gun, only louder. Nothing is visibly rattling inside, and nothing can be heard rattling around when the machine is lifted. Printing performance is not affected at all -- it's fine. Toner is new (noise started before toner cartridge was replaced). Bottom metal plate of machine does not seem to be user-removable to check further. Any ideas?
-Open the Front Cover. -Remove the Toner Cartridge -Remove the Drum Cartridge -Next locate the black gear attached to the end of the Drum and turn it with your fingers. -Check to see if the gear is locked, or difficult to turn. The gear will only turn in one direction. -If the gear won't turn at all, or if it catches while you are turning it, or if you hear the same noise when you turn the gear that you heard when the machine was on, the Drum Cartridge is the cause and will need to be replaced.

Printer wont print and has started displaying "Printing PC" on screen following a visit from a service tech who installed new toner cartidges. He couldn't fix so just left. Any help would be appreciated.
