I've got a Xerox 6110N colour laser printer, all of a sudden it's
started to eat cyan toner - even if there is no cyan in the pages.
Looking at the mechanism there is a lot of cyan toner about, and
the waste tank is full of it - it's clearly just not regulating it
properly.

At the same time its suddenly started making a loud clack-clack
noise when printing, as if it's trying to shake something.

Has anyone any experience of these kind of things. The cost of a
replacement Imaging Unit is far more than a new printer. (And I
know they have a bad reputation thanks, too late)

I'm tempted to start taking the 'no user serviceable parts' Imaging
Unit apart just to see if I can fix it.

Then the next question, can anyone recommend a Networked Colour
Laser Printer?

Bought one about 2 months ago.
Brand new sealed Dell unit, works beautifully.
