Hey anybody used a rubber transfer belt cleaner on TA'S
If so any good suggestions at my local True Value.
Thank you, me

Re: Belt Cleaner
Nope. Is there any reason not to use the existing belt cleaner? =^..^=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.

Re: Belt Cleaner
Existing belt cleaner?
I'm thinking of a chemical i.e. denatured alcohol or facsimile?
In the process of refurbishing a 120k box going out on Mon. & thought I'd give the belt a little dressing.
Hey Blackcat how ya been.
Great weather here, in 70's last couple of days.Comment

Re: Belt Cleaner
I finished the pm on TA250ci & all looks well, except ( isn't there always an except. Really gets my goat).
Anyway mono copies & prints are fine, color copies & prints have the measles (red spots) and offset (blurry) in areas.
In all your wisdom have you a solution?

Re: Belt Cleaner
1) One of our members, tmaged, has had success using a product called Blow Off cleaning transfer belts. I've never tried it myself. It's possible that a primary belt could cause this quality issue. Personally I would use an orange oil based product, then rinse with water, but never never alcohol. It dries out rubber. Initially I thought that you wanted to re-design the transfer belt cleaner blade with supplies available at the hardware store.
2) I've been working on a couple of late season siding and roof jobs. It's rained on me three times in the last two days, and snowed this afternoon for a few minutes.
3) For diagnostic purposes I would emergency stop the machine, because since it seems to affect all colors equally. I believe you are losing secondary transfer, and if I am correct you'll see additional residual image left on the transfer belt after secondary transfer. But equally interesting, you might find that the quality issue is occurring before secondary transfer, and shows on the developed image on the transfer belt.
I would be interested in see what this test pattern looks like. =^..^=If you'd like a serious answer to your request:

Re: Belt Cleaner
Architectural shingles are my choice, really forgiving on those lines.
Just finished my 8x16 shed.
I'll print those test patterns tomorrow and forward.
I was kinda leaning to a pitted color drum being the magenta as the culprit as the blk copies are fine?
I don't have a parts machine handy.Comment

Re: Belt Cleaner
It's currently got 3-tabs, but the owner has approved dimensional shingles. The fun part is that it's 6/12 pitch, and the sheeting has reverted to the texture of oatmeal. There won't be any standing on the current roof. We'll have to tack on a couple sheets to make a workspace to stand on, and ladder jacks. I don't know yet why the sheeting has disintegrated, but I suspect a venting issue or a major moisture source in the attic. Maybe an unvented stink stack? We'll see when the sunlight shines in.
I think that you'll see the same texture on all the 15% color images. I created this test doc for the Toshibas and Lexies, that don't have U089 test patterns that are so helpful for diagnostics. There is also a LTR sized version for the Letter/A4 sized MFP's. I just carry it on a USB stick, then print from USB. Most machines can do that now. =^..^=If you'd like a serious answer to your request:

Re: Belt Cleaner
Watch out BC, I seem to remember a ladder mishap you had last year - stay healthy and let the young dudes do any work above a couple of feet."You can't trust your eyes, if your mind is out of focus" --

Re: Belt Cleaner
I seem to have made peace with "The Widowmaker". I've been up/down it for the last three days with only the usual ill effects (a barked shin or two). The healed ankle seems to do better on ladder rungs than on on the flat ground anyway. Can I use the analogy of getting back on the horse that threw me? =^..^=If you'd like a serious answer to your request:

Re: Belt Cleaner
Two things:
1) Primary charge arcing to the black drum accounts for the black spots. You'll need to change the black drum unit (DK-865: 302JZ93012).
2) Possibly secondary transfer, but before you go ordering the secondary transfer roller first run developer refresh once or twice. You may find that the image fill improves on one or more of the colors. Also run laser slit glass cleaning and do a color calibration. That will also correct the black color registration issue.
From what I see in the CMY, it could be developing. Developer refresh might bring back one or more of the colors. It's common in situations of low color usage to have the color developer die due to lack of agitation. If you need to replace more than two color developing units, it's actually cheaper to get the color PM kit (MK-865B: 1702JZ0UN0). Beware of running developer refresh 4 or more times consecutively: once it starts overtoning, there is nothing to do but replace the developing units.
It helps a lot to see those test pages. =^..^=If you'd like a serious answer to your request:

Re: Belt Cleaner
Transfer belt cleaning is uphill task. The belts is not really rubber, but i think is some kind of formulated conductive plastics or vinyl material, which is durable.I have seen the guys in the printing industry use this stuff.
serive mode u89 and do test prints from there. Should confirm the drum/dev at fault. black prints are good, so the transfer belt should be ok.
Expensive stuff.
cleaning it properly means it has to be removed from the frame assy, otherwise the areas directly on top of the rollers would clean better than the areas that are more flexible. anyone who has tried cleaning these belts would know that. Unless there are visible spots of contamination that is stuck to the belt and can be cleaned off with a soft cloth saturated with toner, it is almost futile in restoring those belts. the belts should last the pm cycle unless it is torn or has mechanical problems. I have seen many times belts almost completely white and perfect prints. more of a problem might be the transfer rollers on the belt or the bushing that those rollers sits on. The bushings carry the transfer voltage to the rollers and sometimes with toner dropping they get covered and cannot transfer the voltage correctly, and those bushing should not be overlooked when cleaning. Most cases, you have to inevitable replace the transfer belt when they are suspected. This is an expensive pm item on a copier and if someone has come up with a definite method of restoring the belt surface, that would save a lot of money then apply for a patent.
just my take on belts here. different manufactures may have variations of belt assy, but they all work generally the same principle. Any corrections or response would be appreciated.THE ONLY THING FOR EVIL TO TRIUMPH IS FOR GOOD MEN TO DO NOTHING..........edmund burkeComment

Re: Belt Cleaner
Thanks for that info.
Even though the blk & white prints are clean and the color prints have red spots
are you affirmative on blk drum?
Can I swap drums around and clean chargers? Is there corona wire or charge roller?
Also do you think the blur on top of color print has a play in this issue?
ThanksComment
