[Misc] Weird noises on Bbizhub pro 951

[Ciprian Gabriel Pop]

Hello everyone!
I have a Minolta Bizhub Pro 951 copier. Recently, I've been hearing a series of rhythmic noises around the toner bottle area, which sometimes become very loud. I checked the toner bottle's positioning, alignment, and even replaced the toner bottle, but the noise persists.

Furthermore, today, with a relatively new toner bottle replaced two days ago, apart from the noise, the machine no longer recognizes that toner is present. Instead, the screen continuously displays the message "toner is being carried" for many minutes.

What should I check or do?

I've replaced a few of those toner bottle couplers. The area where the coupler pins to the shaft the plastic will shatter. The coupler for the 951 is different than the coupler for the 1052 and 1200. Weirdly the bottle turns in the opposite direction. When you remove the hopper unit, be prepared to do a lot of vacuuming. It will be a toner explosion. =^..^=
