Oce CS650 / KM 6500 Drum Issue

Any of you with the 65xx series being affected by the drum cleaning blades flipping and seizing the drum? We are told it is a Konica manufacturing issue, but it is causing some serious down time for us.
 
According to Random there are no known issues with the 6500 or the 6501. They are absolutely flawless engines. ALL Issues are related to poor operator or service technician training. He typed this right after drinking his Konica Minolta KoolAid though.:D
 
we had it. using old drums fixed it (they switched manufacturers when the 6501 came out). they also sent us some experimental new drums but we havent used them yet.

I have had it happen once out of about 40 drums. It happen right at the start. I am now putting on some extra dusting powder. You could ask your tech for one they are pretty cheap. I haven't seen one flip since.
 
Check out copytechnet.com in the KM forum- they have a thread that deals extensively with this issue (called C6500 Flipping Blade)
 
Before someone says that I'm keeping a low profile about this problem. The aforementioned website states my resolution that so far has been 100% successful.

Thanks Random, we'll try this. After having no problems previously (multiple different drums) we've started getting the dreaded flip problem yesterday after changing to drums just recieved from K-M. Isn't this problem meant to be fixed with newer drums? Anyway, as long as your fix works it's no big deal. We've done the advanced operator course now, so my oppo will do the blade trim fix asap, thanks again.

Wouldn't you think KM would put out a world wide tech bulletin on this? It seems like the engineers are trying to re-invent the wheel, when all random needed to do is fix the flat!!!

Random, you should post the fix as much as you can! Nothing I hate worse than unnecessary down time.
 
@Random - KM UK local service have told us that this fix (trimming the blade) can cause streaking on the very edge of the sheet. As we only print SRA3, that could be a problem. Have you experienced this?
 
Had a call from Oce regional service manager today and there are NEW drums showing up any time from Konica.

The blade trimming caused problems for us on 12.5x18. They also tried adhering mylar tabs to the outer edges of the blade, so when it flipped it would flip right back. But it only worked a couple times.
 
have seen this?

the setting of DIPSW 5-5 to “0”. This setting is for “PM counter counts 2 counts when
printing an 8.5x14 and larger size” and is the correct default setting forC6500 USA
model. However, C6500 with following serials is set to “1” mistakenly and that means,
“PM counter counts 2 counts when printing a 11x17 size”. Please change the
DIPSW5-5 to “0” when you install the firmware.

hey steve we have the same issue / they have shimmed the drums and stretched the blades but still get the 2211/2212/2213 codes / it just wont stay running / oce tech said all the other machines are running fine but i dont believe them ///
im in maine were are u guy
 
jay-

Colorado - and Konica tried to tell our Oce techs it was just them at first. They got online and on the phone with other techs and quickly put that lie to rest. Konica had promised Oce a new case drums 3 weeks ago for our account - have not seen one yet. Typical KM from our past experience.
