Is that the same noise you had? Front door open/close
History:
Delivered summer 2020
-after a while maybe 5000 prints customer calls me for a new waste toner box, on visit waste toner box is empty (how can the full allert pop up even the transparent plastic nose is total clear and empty... strange)
-changed the waste toner box, since this i had no calls.
-before a few days i was there to deliver toner and the customer tells me about noise, i checked error counter and made a few tests but i found nothing.
-yesterday the customer sends me a video with the noise.
The noise sounds for me like the problem of the old 220 Series... which we all know. So i expected hardened toner in the cleaning area of the belt and in the auger or in the hole waste toner transport way. But there was only normal toner soft and pulvered, from auger to waste toner.
The gears of the waste toner box and the conveyance assy turned easily.
Now what i have done:
I took out the expansions spring from the old waste toner box to compare with a new orange/blue dotted waste toner box, these were the same length. But why? Anyway i cuttet the spring a bit.
Remember the bulletin: (but i'm pretty shure factory date from this machine is older than the change of the cover)
Since the shape of a plastic cover near the Waste Toner Conveyance Unit
slotting area on the main body was changed, the front end of the conveyance
unit can get angled downwards more than before as it is installed. As a result,
the edge of the shutter may not hit the contact part on the main body side,
and the shutter will not open. When the Conveyance Unit and the Waste Toner
Box are installed together as one assy, this problem hardly occurs.

>>so install waste toner box, take out the bundle together and install again as workaround.
Thanks for feedback.
