Found anything adjusted there?

Ok then tweak it to see if that helps.

Set the TCR K offset to +3 then do toner add followed by gradation adjustment.

For the fun of it reinstall the devtank could be a bad developer bias contact but with a low TCR value i doubt it.

My bad, then don't think its available to adjust on the C220.

So you say you have removed the developer tank and added some toner by hand in there.
Never more than a teaspoon at a time?

Guess you are frustrated by now. Wonder if the dev tanks the techs replaced was new or used?

"Yes for the quantity, it was ok, for the thank, all new in the box.....but I believe that I am going crazy with this copier, I am now battling with one more problem ..... I launch a print from my computer, the printer reacts by blowing, the blue light flashes ..... but that lasts a very long time, nothing in the queue of spots, nothing anywhere, just it blows and nothing happens! In the other direction, the scan is ok from the C200 to the computer but from the computer to the copier, nothing even by launching a test page. Printer deleted then reinstalled, always the same! Crying, I'm wasting so mutch time!"

Ok so you have 2 copiers a C200 and a C220?
You need to get a trained tech out there to sort you out.
Seem like things are going from bad to worse.

So something changed and then the printing stopped. Can you identify that?


Demo and other internal print made from the machine ok?
What if you print from a USB thumb drive?
In the job log on the machine do you see "deleted due to error"?

Finally! After all the time and energy wasted on this thread (mostly allan's time). Should of seen the light once the poster asked what a PM was. This poster had no right to continue to waste time here and should of called a "qualified" tech right from the beginning. And after all the help people offered here do you think the poster would of at least donated $5 or $10. Guess he didn't think it was worth it. And after all this he will still have to call a tech and pay a lot of $$$$$. Like my dad use to say, "there's no free lunch"!

Checked this tread just now and was feeling sorry for Nico....
It's a pitty...
Nico a last try...
Clean your laser windows with the cleaning stick inside of the front door....
Try replacing the ITB... IMAGE TRANSFER BELT if you have 2 machines........
I'm assuming your TCR level is above 6% which quite fine....
Where did you get the new unit...from KonicaMinolta or from Alibaba????????

NO one asked you to leave. I'm not the admin and don't have the authority to ask anyone to leave. I'm not being cruel. If you were near me I would come and out and try and fix it for FREE! That's the type of person I am. Just that you are at a point you need to have a "qualified" tech take care of your issues. Sounds like you called a big company that always tries to upgrade the customer once they see you have an older model. They are like sharks!
You need to find an "independent" tech / small company that is like most on this forum and takes pride in "repairing" machines not to sell you right away. I understand there are cimcumstances where someone might be in a remote area and that's where it can be a challenge. Perhaps put an ad in local paper for an independent tech needed or even post to see if Tech on this forum might be in your area/country? Hopefully you can get these issues resolved and can come back here for successful help with a different issue in the future. At that point it would be nice to see you are a contributer but will still get help here regardless.

Once again sorry if I came off the wrong way but it comes to a point that just can't be resolved online.

Best of luck!

Nico is not a technician and maybe he does not understand that these machines sometimes the problems are very complex and you need professional experience to understand other professionals who are trying to help you.

"Thank u very mutch for this post, unfortunately, of "small" technician I did not find in the sector and all the others arrive at the same conclusion: to change material ...... it is thus, with regret, because I need it for my work and that I cannot wait very long to seek and still seek, that I will make this change. one more copier that will certainly fill the container leaving for an underdeveloped country where he may be able to find a second life .... maybe not! I would so much have liked to share the solution that worked, but it is so. Thanks again to everyone!

" The unit was new and genuine, a real Konika one. I have just one copier and wont have the possibility to try to change the transfer belt to see if it's the problem, thank's for your intervention"

Re: Bizhub C220, does not recognize new black toner, pale black copy

"Thank you so much Allan for all your advice, I will leave the site. Unfortunately, the technicians I am brushing up on do not give me the solution and I actually had a lot more interest from you than from the people I paid to do it here in Montpellier. As Copyman asks me, I will therefore disappear. for information, the Minolta technician who came by yesterday did not help me out but sent me a proposal to buy the machine for € 400 and then offered me the sale of another machine for € 4,350 ..... not judging the interesting troubleshooting. It's to vomit!I apologize for the time you have lost for me and the considerable energy in the service of a stranger. Yours sincerely. Cordially. Nicolas."

Do this on my own free time so i don't mind helping guys who try, believe in the right to repair these machines.
Don't give up yet. Its a pity you can't find a decent tech around there. There are good secondhand finds out there.
Trick there is to find a machine that just came from contract and the PM condition is good.
Then only would it be a good buy.

But continue to repair the machines you have.
Probably a simple problem one of use can repair in less than 30min.


Curious about the total count on the machine?

That slipped my mind.
Sometimes the simple things that gets overlooked.
Could be a soiled laser glass.

Otherwise a bad bias voltage connection to the dev tank.
