Is this the first time you have replaced the drum on that machine or have you replaced it once before? I had a similar problem on a 283 when I replaced the drum and cleaning blade it started printing completely black pages. Couldn't find any fault so put it down to the main charge. We fit a whole new Imaging Unit and it works fine now.

it happened to me.

i installed the registration dust catcher on cockeyed, running the f8 i heard unusual noise.

i believe i sucked in millions of paper dust particles into the developer unit.

after i replaced the drum, dev and dev unit again it was 95% better but still not perfect. Luckily it wasn't noticeable on normal printing.

This will be the second time I have reset the machine with new drum and developer. It's a weird deal

Re: bizhub 223 copies bad after drum change

I was hoping it would have corrected itself. like I light struck the drum. but I got a call back today. so I am going to replace the developer unit now. thanks for all the help. question.? new dv unit equalls new developer right? they only have 200 copies on the new developer. can I reuse? what are your thoughts guys.

and I hope I can just use the same drum unit. and redo the gradation


sorry so many questions

Re: bizhub 223 copies bad after drum change

On this model developing unit does not include starter. I hope you ordered both.

Does all the stuff in the manual include?:
reset life
TCR sensor adjust
gradation

That's what needs doing. =^..^=

Re: bizhub 223 copies bad after drum change

I am aware the developing unit and starter are different part numbers and this is not a new machine so it is not included. Most aren't. I've answeres my own question. I am going to bite the billet and replace the developing unit and use fresh starter. To prevent contamination. And yes I have the manual and will perform all the right adjustments

Re: bizhub 223 copies bad after drum change

just an update. it was the developer unit. I noticed there are a small handful of white spots still but nothing like before.
just wanted to thank those that helped with suggestions
