Ricoh MP6001 Dark Band

Looks like the drum drive is slipping. Slim as usual is correct about the process, lead edge versa trail edge but the sample provided looks like you have a bit of compression on the image after the black banding.

Good luck

I was thinking the same thing.

you can take lacquer thinner and rag and really clean the drum shaft..
I would put a bunch of paper over the transfer unit b4..
You can clean the grid wth dish soap and hot water n rinse real good...
the wire can be cleaned wth pencil erasure then alcohol..
Make sure the frame is wiped clean wth alcohol..
also all filters keep clean,inside and rear..

Dark band and shrinking image at trailing edge on first copy/print only.
Any ideas?

f the consumables are all ok, try to clean / replace the air filters, in particular that of the corona c.c. , then, do the last update of the engine & system / copy, and here you will now have available sp-3-990-001 = regulate air fan speed, this should improve the ejection from the print engine of the ozone created during the process of print (0=slow,same a previous firmware 1-fast), the filter must be clean, i recommend!

I finally got back out to this machine. Flywheel screw was missing causing whole problem.
