Hi there!
Take a close look at the toner-recycling-drive. Had a similar noise problem: the noise came from wornout gears of this drive.
If you have to change them: good night, itīs a hell lot of work!

hi thanks but where is the tonner recyling drive located in the machineYou need a service manual if you do not know where the unit is. Try having a look at the rear of the image units!

Sounds like an interesting problem, havent seen this before.

there is something else going on here which is to do with colour developing/drum drive or colour transfer roller extension/retraction.

in black only mode the colour imaging unit drums and developer rollers do not rotate and the colour first transfer rollers are retracted (depending on acs config, im not sure if it even applies in service mode tests)

if its ONLY happening in colour mode I'd be inspecting the colour imaging units, & main drive unit.

You say youve replaced the fusing drive section & transfer belt, so that rules out the first transfer roller retraction mechanism.

Please let us know what the solution was when you find it.
