Xerox Versant 80 - NCR / Horizontal Streaking

[rwyeth]

I am aware that the Versant 80 is old and I've gathered that it has a history of 2nd BTR issues; but, until I upgrade, I'm keeping it alive. It developed this defect several months ago. It appears every two or three sheets as a horizontal smudge. When it first occurred, I replaced the ITB Cleaner Assembly; that seemed to solve it for some time. But, it has now come back. Could it be related to the NCR, the 2nd BTR issues (mine is surely shot), or just a damaged ITB? Also, attached is a picture of the decurler roller; is all of the black stuck-on-toner a result of the bad 2nd BTR (likely from running so much NCR)? Can someone explain how a 2nd BTR issue causes so much toner build up on the back of the paper and bottom of the paper path (rollers). Is it because a rough 2nd BTR roller can't be cleaned effectively of waste toner?
Thank you for all of your help! I'm also open to suggestions for an economical machine to run my NCR on.

Viem, že Versant 80 je starý a zistil som, že má v minulosti problémy s druhým BTR; ale kým nevykonám upgrade, nechám ho pri živote. Táto chyba sa u neho objavila pred niekoľkými mesiacmi. Objavuje sa každé dva alebo tri listy ako horizontálna šmuha. Keď sa to prvýkrát stalo, vymenil som čistiaci valec ITB; zdalo sa, že to problém na nejaký čas vyriešilo. Teraz sa to však vrátilo. Mohlo by to súvisieť s NCR, problémami s druhým BTR (moje je určite opotrebované) alebo len s poškodeným ITB? V prílohe je aj obrázok valčeka na vyrovnávanie zvlnenia; je všetok ten čierny prilepený toner výsledkom chybného druhého BTR (pravdepodobne z používania veľkého množstva NCR)? Môže mi niekto vysvetliť, ako problém s druhým BTR spôsobuje toľko hromadenia tonera na zadnej strane papiera a na spodnej strane dráhy papiera (valčeky)? Je to preto, že hrubý valec druhého BTR sa nedá účinne vyčistiť od odpadového tonera?
Ďakujem za všetku vašu pomoc! Som tiež otvorený návrhom na ekonomický stroj, na ktorom by som mohol prevádzkovať svoj NCR.View attachment 294597View attachment 294598

Good day. The financial unit needs to be cleaned.

If that artifact in the photo perpendicular to the paper feed direction (cross process) and on the bottom of the sheet, you probably need to replace or refurbish the 2nd BTR. This pattern happens to my 3100 and 4100 and is usually the 2nd BTR being done.

We keep a C75 alive to run NCR. Versants get premature wear on a bunch of components by NCR according to a number of techs I've talked to.

it doesn't look like 2nd BRT to me. It looks like the upper inside of the fuser assembly, like the sheet is buckling and rubbing into it. The inside of the fuser cover likes to collect huge amounts of residue toner over time. I'd check the inside of the lid. While you are there, check the "timing wheel". A badly caked timing wheel can cause the paper to start to buckle because the fuser is running at a different speed than the imaging.

I know the 80 is different than our equipment, but it should be similar enough that these photos should be helpful

Dobrý deň. Finančná jednotka potrebuje vyčistiť.

Thanks for the reply. However, I don't think google translate is translating it quite properly. Clean the financial unit?

Yes, it is perpendicular; but, it is on the top of the sheet. I'm certain that I need a new 2nd BTR. The roller looks like someone took a grinder to it; but, I've been putting it off knowing that the new one will also get ruined by all of the NCR. I just wasn't convinced that the 2nd BTR would cause this perpendicular line on the top of the sheet.

Thank you. I will definitely check those couple of things. I put a whole new fuser assembly in it a few months ago after a piece of cardstock managed to break off a stripper finger and take a nice gouge out of the fuser belt. But, it may be time to pop the cover and take a look.

If you run a lot of single color ncr you may want to look at a digital duplicator to take some of those ncr jobs off the Versant. It’s okay to run ncr on the Versant but, eventually, you’ll have issues if you run too much too often. You can pickup a used digital duplicator for a very reasonable price and you can also run your single-color envelopes on one a lot faster than a any toner device will run them.

Not sure why you don’t just replace or rebuild the bad 2nd btr unit if you know it’s no good. If it’s really that old and in bad shape it’s likely that it could be full of waste toner, and that’s going to add problems to the mix also.

Thanks for the input. I have a new 2nd BTR arriving today; I haven't replaced it because up until this point the print quality has been acceptable and I just wanted to get as much life out of it as possible. But, it is probably stupid of me if it might cause more problems. Also, I am interested in digital duplicators and have wondered about inkjet. However, I don't really see any suitable inkjet options yet.

Are there specific Riso duplicator models to be on the look out for?

Well, I replaced the 2nd BTR, and cleaned up some melted-on toner on the rollers and decurler. Also, I took a look at the ITB while I was in there. There is a definite mark on it that aligns with the defect I'm seeing. I rubbed down the spot on the belt with rubbing alcohol for now. I am able to print now without issue; but, who knows for how long. Also, I'm not sure what caused the mark in the belt (it's a bit of a short rough line). The machine doesn't claim to be due for a belt; but, a couple of the developers are a little past due. I guess I'll see how it goes and if I need a belt, I'll do the developer then. Here is the old 2nd BTR.

oof, that 2nd BTR is trashed

I run two older Ricoh HQ9000 duplicators but I don't think Ricoh makes them any more. Don't look at any duplicators that print under 600x600 dpi or you won't be happy with the output. Even at 600x600 you'll have to be careful about customer expectations when printing screens. These duplicators fall into a niche market, not everyone likes them but for corner copy envelopes and ncr work they are speedy and inexpensive to run. Over the years I've also run thousands of clasp envelopes without issue.

My limited experience is that Versant parts like 2nd BTRs, IBT belts, Fuser belts, developer housings, and especially drums, don't last their expected life. Spitball 60% of expected life.
