I have inherited this copier (no history of previous repairs/services), Kyocera Taskalfa 250ci with only 28k page count. It has very strange problem - all prints and copies come out with lines. I took it apart, cleaned each drum, put it together and was working perfect for about day. This was on Friday, we were closed on weekend, on Monday lines are back. When I try to take it apart again I noticed that Transfer Belt stick to all 4 drums, leaving part of transfer belt on drums when I unstick it. Is anybody experienced something like this? Is this belt defective or drums some how getting hot (or electrified) and melt transfer belt? What I should replace or adjust - please advise?

Re: Taskalfa 250ci - Transfer Belt stick to all drums over weekend
Ok you're an end user to start and you have possibly screwed up ALL the drum units by messing with them. The units are designed to be changed as a unit not taken apart. You needed to do individual colours to determine if it was a drum or transfer belt issue.
different coloured lines all together indicate a transfer cleaning issue - one colour could indicate a drum cleaning issue.
if you want to do your own servicing then get hold of a service manual but remember if you bugger it up its your fault. -
Re: Taskalfa 250ci - Transfer Belt stick to all drums over weekend
It is not cleaning issue. And I did not take drums apart. Yes I read service manual - all 626 pages (Rev. 6), nothing in manual about sticking transfer belt to drums. All 4 drums stick to the transfer belt over weekend.
Yes I have new 4 drums and transfer belt to replace with but asking experts here what can cause the problem described above. I have feeling that it is settings somehow responsible for that.Comment

Re: Taskalfa 250ci - Transfer Belt stick to all drums over weekend
No chemicals were used to clean. Whatever transfer belt made from (rubbery/plasticy substance) was scrapped off drums with plastic scraper. Transfer belt was wiped off with clean cloth. Will post pictures tonight.Comment

Re: Taskalfa 250ci - Transfer Belt stick to all drums over weekend
I have narrow down issue to two possibilities:
1. Transfer Belt deteriorated and sticking to the drums?
2. Somehow drums getting power in stand by mode, getting hot and transfer belt melting to the drums as it is resting on drums. Or static electricity doing same?
It takes little bit of effort to separate drums from transfer belt when I removing transfer belt assembly. So I am leaning toward melting issue...
At this point my goal is to replace all parts and to make sure new transfer belt did not stick to new drums?Comment

Re: Taskalfa 250ci - Transfer Belt stick to all drums over weekend
Well you have to find what really happened there before you install those new drums and transfer belt. those things are quite expensive and another failure would be costly. The only thing i could think of is alcohol in contact with toner produces rather stick stuff. Also if the machine was fine before the cleaning, then you have to retrace your steps in the reassembly process that you took.
In trying to see what may be at fault here. check all the fans and make sure they are working and in the proper orientation, that is exhaust and intake.THE ONLY THING FOR EVIL TO TRIUMPH IS FOR GOOD MEN TO DO NOTHING..........edmund burkeComment

Sticking Transfer Belt is the reason I took machine apart. So the problem was there before I got this copier.Comment

Re: Taskalfa 250ci - Transfer Belt stick to all drums over weekend
Really need a picture. The drums won't get hot or power in standby mode so as what's been said don't replace the drums yet.Comment

Re: Taskalfa 250ci - Transfer Belt stick to all drums over weekend
I have seen these stick due to old age/belt going bad/sagging. If you didn't kill the drums cleaning them you should be able to just replace the belt. I have cleaned my drums many times before the boss let me replace the belt.
These have a problem with age killing drums=spots, belts = sticking ( like you have) or the rubber band(ish) drive under the belt coming loose and killing the belt/jamming the belt drive. Fusers over temp or rip. temp can be reset if you are willing to spend the time to do a total take-down and know how to reset, Via the freezer, the over temp device. Other than that,.. they work great, LOL.
My 2 cents.

Re: Taskalfa 250ci - Transfer Belt stick to all drums over weekend
I think what the other gentleman are getting at, is that they (and I) have never seen a transfer belt stick to a drum. A few possible explanations:
Chemically corrosive environment, degrading the transfer belt.
Primary belt is touched with some corrosive agent.
Unusually sticky media adhering to the primary belt, the transferring to the drums.
Let me ask you this: Did you remove the fuser and primary transfer belt before attempting to remove the drum units?
As long as the new components are not exposed the the same corrosive agent, I do not see how this could re-occur. I'll be watching for the pix. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Yes, Fuser first then Transfer Belt which was difficult to remove as it glued to all 4 drums.
I think this copier was sitting too long without use thus transfer belt decide to go bad due to aging. when I took copier apart I did not see any signs of previous repairs, everything was looks like virgin state.Comment

Re: Taskalfa 250ci - Transfer Belt stick to all drums over weekend
just spoke to our shop techs here and asked about this. They have done numerous of these machines and never seen this issue. What they have problems with sometimes is the rib on the underside of the belt becoming unstuck and wrap around the belt roller. I think blackcat explanation sounds reasonable. one of our techs also mentions that installation and removal steps must be followed step by step as to the service manual.
Then again gar the pilot said he has experienced the belt degradation due to old age. so at least one other guy has seen this. Interesting.THE ONLY THING FOR EVIL TO TRIUMPH IS FOR GOOD MEN TO DO NOTHING..........edmund burkeComment
