Konica Minolta Bizhub C7000 - Part keeps rotating, while it shouldn't

[Honpress]

When you insert the primary transfer belt unit, the first time you power up it must make one rotation for the coupler to engage, so the belt will be still for a single rotation of the drive coupler, then from then on rotate with the drive. Can I see the video?

Hi Blackcat,

My father said the same. I made a video of turning the transfer belt by hand, where you can see the belt itself stays put and when I press the (don't know what to call it) levers with the springs on the side, the belt will rotate. So it seems the belt isn't tense enough? Don't recall the strings were always this strong, I made them a bit shorter so the pull more, but that doesn't help. Only when I keep these 'levers' a bit down to give tension to the belt.

I made a link via Wetransfer. I don't know how else I can share a video or how to make a link of it without youtube etc..

Excellent video. The belt should rotate without additional pressure. One or more of those bushings and bearings is difficult to turn. You'll need to remove the primary transfer belt from the unit, and examine each or the rollers to determine which roller is difficult to turn. I suspect that there is a seized ball bearing.

Uitstekende video. De riem zou moeten draaien zonder extra druk. Een of meer van die bussen en lagers zijn moeilijk te draaien. U moet de primaire overdrachtsriem uit de unit verwijderen en elke rol of de rollen onderzoeken om te bepalen welke rol moeilijk te draaien is. Ik vermoed dat er een vastgelopen kogellager is.
