I have a WBA 12 SS in the S2000 I'm trying to sell.
It was taking new 10's and 1's all the time. Occasionally it would take a new20 and a new 100 dollar bill.
Until just NOW, it was still taking 10's.
Now it won't take anything.
I've checked/cleaned gunk off belts, cleaned optics. Everything looks good from my limited knowledge on these.
I've changed nothing in my settings that I know of. I changed the game and that was fine - the DBV worked until just now!
:banghead: :banghead: :banghead:
Does this machine not want me to sell it???
-
Might need a calibration. Ping Roz and see if she has any JCM calibration papers for sale.
Thanks,

I think this may be beyond my skills...
I did swap out the transport with another working one and it's fine. Just wanted to rule out any machine settings I may have messed up.

You can send the head (front end unit) out for test, cal & repair, there are vendors here that can do it, some for a flat rate.
-
But is it just cheaper to get a used working head?
I just cleaned the optics... maybe too harsh but I used plastic lens polish. I carefully wiped it off and now it takes 10's again.
What's frustrating is that I have a potential buyer for it now... which I'll have to call and tell him it's no longer available.

It is late tonight, you might get more expert help tomorrow during better hours.
I'm not a WBA expert, but I think they generally say to use isopropyl or denatured alcohol to clean the rollers and lens. *EDIT-This is wrong, do not use alcohol to clean a bill acceptor head*. Be careful with any belts, don't want to stretch them or use a chem that will break down the rubber material. Be careful not to leave lint or other material behind when cleaning.
Have you checked the game settings to make sure all bills are enabled for acceptance?
It is possibly cheaper & quicker to replace it rather than send it out. You can check several places like ebay, rudy's deals, and here on NLG (put a WTB post in the classified section). Maybe if you get it partially working with a good cleaning you can go ahead and sell the machine, tell him the bill validator is acting up, that you have ordered another bill validator and will replace it when it comes in (hopefully it is a local sale). If handled right the buyer can see that you are being conscientious about this and it will turn out as a positive thing. Used slots have lots of mechanical parts with wear time, any of them can cause a problem at any time.
You are getting the head fully engaged when installing it, right? and ensure all of the connectors & cables are completely plugged in to the bill validator. If any cable is not making proper contact on the validator or on the backplane on the other end you can have problems. Maybe something concerning the bill validator got disturbed when you were doing the game change and clean up.
-
The other thing it's doing is not pushing the bill out with much force... seems loose. I didn't notice that until it started to reject all the bills.
I wish I could just shove a DBV-200 in there. I have two of those laying around! :rotfl:
I think I may do exactly what you said and just get another one... or two maybe!
Roz?

oops sorry I meant that "Roz" as a message to her... not a question. :propeller:
Thank you though... I have all her info... buy from them frequently.
-
oh, I thought you were asking who was Roz. :duh:
If you decide to get another head and it turns out you can fix this one you can probably use it down the road so no harm. In your first post about this problem you said even back before you did the work on the machine it would sometimes take a new $20 or $100. That sounds like it was a little flaky even then, since it should either take them all the time or never. You should be able to see what version of software is in the bill validator by checking for a label, and then check the JCM website (or ask here) to see exactly which bills it should accept.
It seems like someone said that a DBV-200 head would work with a WMA transport but I don't remember the details so I might be mixed up on that, and you might need a different head cable to do that.
When you were cleaning things in the WBA did any of the rollers or belts seem overly loose, sloppy? Was there any slick stuff like grease or other substance on the moving parts. When it spits the bill back it should be pinched firmly and come out strongly. Maybe that is a clue the bill is also slipping when feeding inward and it doesn't get scanned properly.
-
How bad do you want to sell the machine ? It's up to you but I can test yours in a machine, and I have some spares if yours won't work. Just a guess but it's about a hour and 15 minutes from your house to mine. ( about 1/2 way between Palmdale and Victorville )
Check that all the dip switches on the transport are in the up position ( up is off because the dip switches are installed upside down.) It's possible the BV lost it's CRC so open and close the main door latch 3 or 4 times. ( A S 2000 will recalculate the CRC using the door latch, a Game King or I Game will not ) Are you sure your getting the cash can in all the way ? Is the cash can door switch bypassed ? ( If no, it needs to be )
No you are not suppose to use any kind of alcohol on the optics or belts. alcohol drys out the belts and it will cloud the plastic optics. What I do is spit on a rag and spread my DNA all over the optics.
Lets get a couple of terms straight, a WBA has two main parts, the head and the transport. To remove the head there is a round bar just above the flat bar you push down to remove the complete unit from the machine. Push down on the round bar and pull on the bill bezel and the head will come loose from the transport. ( it just plugs in ) Now I'm maybe going to overload my butt on this statement, but I think any head will work on any transport. In other words you could say put a head from a 10 transport on a 13 transport.
Here's one thing that anyone that's going to mess around with BVs needs to learn. When a BV cycles each time the machine is turned on that cycle will always sound the same, sometimes faster or slower but the same sounds will be there. If the sounds are off, that BV is not going to work. There is no way I can explane the sounds you just have to listen and learn.
NO a DBV head will not fit on a WBA transport.
-
Heads will work on just about any transport. Sure, if you put an older head on a newer transport, you may not get "4 way" bill acceptance, but it will work.
Mark, you have other S2000s right? Save yourself a drive to Buzz's house (unless you just feel like driving) and snag a validator out of one of those for now. You can trouble shoot or repair the problem child WBA whenever.
-
Any wba head will work with any wba transport. The 1 way vs 4 way acceptance is purely a transport issue. The WBA 10/11's do not do 4 way acceptance because there isn't enough room in the memory/eprom to have the necessary data for 4 way acceptance, basically "scanned" images of the bills in 4 directions, that is really the only reason.
-
Thanks Buzz for the offer - tempting to take the that drive, but I have a lot of work days ahead so I may have to make due with what I have.
I already used a dab of 99% isoproply on the optics. :duh:
But it worked after that for awhile... and then the next night, it went back to the intermittent taking of bills. Then it stopped again and I used the plastic lens cleaner I had... and it resumed taking the 10's. That's also when it took a 20 dollar bill.
Then it went back to being intermittent and then taking only a 10 dollar bill once in a while.
I KNOW I SHOULD HAVE KNOWN BETTER and not used the alcohol! I'm sure it's written all over NLG to not do what I did. :banghead:
I have flipped up the head of course, when I "cleaned" the optics. Haven't tried removing the head but maybe I will later after work. I'll check the DIP switches just for the hell of it, but again... it has sporadically taken 1, 10, 20, 100 dollar bills. I did have the entire unit out of the machine. I wiped the belts and looked for any debris. The belts DO seem loose though. Pressing POST now because my laptop battery is dyi
-
Well a offer is a offer and it's good day or night.
I would say the CRC is good if it excepts bills sometimes. Removing the head doesn't do a damn thing except making you think you did something. As for as loose belts I have never tried to replace one and it looks like a pure bitch to replace one. Now if a belt is so loose that the bill isn't pulled in fast enough there is a good chance the BV is going to reject that bill. And if a belt is that loose the damage is already done so it won't do any more harm no matter what you put on the belt. That said in the rock plants if a conveyor belt started slipping they would squirt Purex on the drum. ( same stuff your Wife uses in the laundry) Now I'm not telling you to use Purex but if a belt is a lost cause, why not !! I've been known to wipe the belts with soap and water, or even use a pencil eraser to take the glaze off of them.
Let me address something you said in reply #2 about your skills in using calibration paper. Your correct in leaving this to the experts. It's quite a mess to attempt on your own, first you have to remove the BV from the machine and turn on #5 6 7 &8 dip switchs next reinstall the BV, turn power on to the machine, now the hard part, insert the calibration paper like a dollar bill, black end first, no right or wrong side. BV will pull and push out the calibration paper a few times and when done will reject the paper like a bad bill. Remove BV from machine, turn dip switchs back to OFF reinstall BV and your now a expert on recalibrating a BV. Here is a link to a pretty good Youtube video that was made by one of our members when he worked for JCM https://www.youtube.com/watch?v=Ns6gckieHyo (https://www.youtube.com/watch?v=Ns6gckieHyo)
-
Bottom line, I on your situation, Just swap the G*%# D%*#^ validator with one of your working ones!! Sorry, but if you are trying to sell a game, then sell it!!!
-
I'll do it! But now the buyer hasn't returned my call back... hmmm
I can use the WBA 13 from my Top Dollar or the WBA 11 from my Butterfly Sevens. And difference I should know about?
And I do want to replace these or fix my other WBA 11's. I have no idea of prices if I want to replace them.
UPDATE - I put in the WBA 11 from my Butterfly Sevens into the game for sale. Now I hope the guy calls back. :CaptainHappy_worried:
-
I really really doubt that you have a WBA 11 in a S 2000 Oh sure a bunch of wiring could be changed around to make a 11 fit but why would anyone want too.
Now in this very thread three of us told you that any wba head will work with any wba transport, so when you are trying to figure out which WBA you have look at the tag on the transport and not the tag on the head. The electrical plug from the transport to the machine on a WBA 10 & 11 is different than the plug on a WBA 12 & 13 Mark do you still have a S+ with a WBA ? If you do pull the BV out and compare the rear plug to a BV from one of your S 2000.
-
This is what happens when I post late after work and after wine... :duh:
It IS a WBA 12... sorry about that Buzz.
I'll check out the rear plugs on my s plus, and s2000. One of my s2000's had a MARS validator as well.
And I'll compare my two non functional transports that I've been messing with. One still takes 10's all the time. I'll check the transport to see what they are. The heads have a hinge I can see. I've looked through NLG ( to avoid repeating the same questions!) but I can't see any post on head removal. I'll mess with them when I get home.
I just hope this buyer... buys! The machine is working fine now that I swapped out the BV.
-
Pull down on the little round bar, and use a flat head screwdriver to pry the head away from the transport. They will not release on their own. Just pry on them just a tad to get them started.

I figured it out before you replied. But... :thank_you: though!
Yes they took a little prying but I could see the direction the head would go... so I pulled and the unit came free.
And... while I had time tonight (before all the little goblins and ghosts got here) I spent more time cleaning the belts and rollers on the "broken" one. Stuck it back in to its slot and guess what? Now it was back to taking 20's again. It took a 20, 10, and the 1 dollar took a few times. So I took it back out again and found MORE gunk on the rollers that look like they're the first to grab the bill. Using a Q tip, I swirled all directions around those and the free-rolling ones past it... got a LOT more gunk off them.
It looked like a combination of cigarette tar, hard liquor, and probably coke (not the white stuff but the drink).
Slipped it back in and now it's consistently taking all bills. So I don't think I need to fix this one. I think my problem here is not only the optics but what rokgpsman said about the bill not being pulled in properly or proper speed due to the slip on the belts/roller.
I have one more from the second slot I want to flip, so I'll do a super cleaning on it this weekend to see if I can get two for two.

Sounds like you are on the right track to getting it to work, likely just needed a good cleaning. If the bill was slipping on the rollers instead of being pinched firmly that would account for the intermittent operation. Keep in mind I was wrong about using alcohol on the lens, I thought they are glass but turns out they are plastic. I looked at the JCM maint document, they say for cleaning to use their special cleaning paper or as an alternative you can use a damp lint-free cloth or qtip with a little mild soapy detergent mixed in the water to wipe things down with. Too bad you can't just put it on the top rack in the dishwasher.
JCM also recommends to clean the BV twice per month (every other week) when used in a busy casino. I bet that doesn't happen, probably only gets cleaned when it stops working.
Hopefully you'll get that machine sold as planned.

JCM cleaning paper...snake oil.
Thanks,

Cleaning paper? Or Calibration paper? Ive carried calibration, and will again if I have the requests. Ordering 1 at a time from Happs will KILL you on shipping...
-
Roz are you all out of the calibration paper?
-
I may have ONE left??? If there's any interest I can order more. Truth is, the shipping sucks just about as much for me as it does for you...I get a little break, but it still hurts.

I can't see anywhere to order... and I'm also thinking this isn't for small time people like me.
With that said... the BV I had cleaned and was working is now back to not really working!
It will still take 10's about ever third try. But the bill still goes in weird... not a smooth pull all the time. There's slop on the pull in and the reject out. When I try 20's, it's worse... as if the 20 is made of something different.
I've cleaned the hell out of it. The rollers are debris free. The belts are clean.
I think this is happening in the head portion and not the transport. Do I change the belts next? Do I need to "rough up" the belts? Maybe they're too smooth???
I tried a search on NLG and that was entertaining... spit... dna...lube...
-
A thorough cleaning can only do so much and it sounds like you have given it quite a bit of cleaning, so you could have something like worn/loose/slipping belts, etc in the mechanism or a weak motor or an optic problem that is causing a scanning problem. You'll have to decide how much time and money you want to spend on it trying to get it working, or just replace it. Some repairs, especially intermittent operation ones, are difficult to resolve.
-
Yes I understand that may be the next step. I wish I could "fuse" the two complete units I have and get one working... but I've already swapped heads and have similar issues. Both of these were tested working not too too long ago and they both were supposedly bought "refurbished" but I already see that's a very loose term!
-
Bottom line, I on your situation, Just swap the G*%# D%*#^ validator with one of your working ones!! Sorry, but if you are trying to sell a game, then sell it!!!
I SOLD IT! I SOLD IT!!! :applause:
I replaced the BV with one of my own, changed the listing to show that it takes all bills now and got three calls this morning. First person who came bought it. My first "flip." It took more work than I realized but it was worth it. And it was a GOOD feeling knowing I had gone through the machine and had everything (bulbs, new battery, speakers, etc) working. The buyer knew that too.
Now I can slow down and learn more and hopefully fix or swap heads in the two BV's I have.
-
For whatever it's worth... I found what I think was the main problem with BOTH my "bad" bill validators.
Dirty belts and optics may have still played in with bill rejections but the sloppy/weak bill accepting and rejecting seems to be caused by the rollers that the bill initially hits.
I got the one BV, that was never taking bill,s to taking everything the first time. The problem is that it only works awhile and then the rollers seem to revert back to slipping. I'm not sure what else to try to make them "grippier." It may just be that I still replace the entire head anyway.
Comments?

If this is an older BV a lot of people would just replace it to do the repair and get something newer/more reliable at the same time. At some point it becomes more trouble with taking up your time than it is worth. Plus if you sell the machine you don't want to be getting calls from your customer about its flaky operation. That might hinder future sales for you since many people don't stop at buying just one machine.
But if you are considering junking it anyway or if it is on your personal machine you don't mind messing with now and then you can try more aggressive things than mild cleaning. Over the years rubber gets glazed and hardened, looses its grippyness. If you ever watch drag races you see the guys pouring bleach on the ground to do a burnout in with their rear tires. Bleach softens rubber and make is grippy but the effect is not permanent. You can apply a small amount with a dampened q-tip and let it work for a few minutes. Don't expect the rubber to last forever if you do this but it could extend the working life of your BV head. You can also look at replacing the rollers, get other rollers from internet suppliers or take them off similar BV heads that were junked for other reasons. Or you could try swapping the front rollers with the rear rollers. And you could try making small horizontal slice marks with a razor in the rubber to increase its traction on the bill. This will work for a while until the little slices wear down or fill with dirt & grime from the bill. In short, there are some measures you can take, but in the end mechanical parts wear as time goes by and you have to replace them or the entire device they are in. Even something only a few years old might have countless hours of use, depending on where it was in service.
-
:agreepost:
Thank you... that was very helpful!
It just seems a waste to toss the entire head but the time factor is definitely a consideration. This particular one was last serviced in 2008. I have two BV's (supposedly working) on the way so I'll probably swap out a good head to get this slot fully operational, and yes... I know a lot of people just can't have one... hmmm... sort of like Lay's potato chips! :rotfl:
In the meantime, I took this one apart and saw that those roller surfaces are just O rings. So I'm going to head to my hardware store tomorrow and see if I can find something that will work. That would be nice if it was easy as that but I'm not sure if that's a special size or not.
-
I found some O rings at the hardware store that were slightly smaller but the proper thickness. I put them on the BV that was rarely taking any bills.
I reassembled the head and reinstalled it in the transport, and back into the slot.
Now it takes EVERY bill of every denomination with, so far, no rejection. I've put in about 20 bills of all conditions. It's taking them all.
I think this IS the problem if there's even a slight slip when the bill is accepted or rejected.
My other BV was taking some bills some of the time. It didn't seem to slip as much. I replaced those O rings and got the same result: 100% acceptance, so far.
I don't know the long term yet but I don't see any reason for failure. Maybe getting the exact O ring is better but these seem to be fine.
It would be GREAT to hear some more comments on this.
If there's enough interest, I'd be willing to create a "how to" on this problem and a step by step (with pictures) on how to do this.
-
Sounds like you solved the problem with some low cost parts, nice going! Were both BV models WBA-12 and how many O rings did you replace on each one?
-
Both were WBA 12's. The shaft that has the rollers (that grab the bill first) have two O rings on each roller, each side. So 4 O-rings each shaft. It's really not hard to disassemble the head. The hardest part is those stupid circlips but I just put tape on one side of each so they don't fly off into oblivion when they come free.

One of the guys I used to work with irreverently called them "jesus" clips. Almost every time he removed one it would fly off in some direction and he'd yell "jesus! where did that thing go!".

I knew there was another name for them... that was cleaner than the one I wanted to post! :censored:
I HATE those things... but tonight I had the brilliant idea of taping one half of each one... kept them from leaving the scene!
-
Did you also have some older DBV models that were working intermittently? I'm wondering if a similar fix would help them, but I think they have rollers instead of O rings?
-
Well I just had these two that were in the two s2000's that I bought to flip. But the first one, I ended up putting in one from a newer machine I had. It was taking 20's consistently so I just stuck that one in and sold it.
The only other one I had that was not working was an old DBV 145 (Hope Buzz doesn't read this...he'll tell me to throw it away!)
I just cleaned the optics and belts on that one and now it's working fine. Of course, it only takes 1's but I don't care since it's a nickel machine.
I'm 99% sure this could be a problem that has been overlooked and where head units may have been tossed for a problem that cost me 92 cents to fix for each one.
Maybe I will go ahead and create a "fix it" post for this problem. I think it would be worth it?
-
I have 2 heads that don't take bills or take 1 every 20 or so. I'm going to try your fix and will post results.
-
Great... let me know.
On the O rings... make sure you get the proper thickness. There were some that were the same size but thinner. I ended up with some slightly smaller (but same thickness as originals) but was able to easily stretch them over the rollers.
-

Or he'd say to use his special cleaning saliva! Maybe we can get him to bottle that stuff in 1 oz glass bottles with an eyedropper.
Documenting what you did might help someone down the road with the same or similar problem so I'd say do it. There are all levels of experience and someone reading it might fix their problem because of it. Too bad the DBV rollers are not as easily available as those O rings on the WBA models.
I think that before JCM stopped supporting the DBV-145 they released a few updates for some of the newer style bills like the next generation $20. So your DBV-145 could get the eprom updated to the last revision of software JCM released and it might let you use $20 bills. You'd have to find someone with the last DBV-145 eprom release but they are probably out there. That would let you use $20 bills on that machine with the DBV-145.
-
Yes I think Buzz should bottle and sell his special cleaning saliva! It would be a hit. "Buzz's mystery elixir." Hopefully he'll stumble on this thread and start bottling his DNA.
rickhunter - any news on the BV fix? I'm curious.
-
Didn't work for me. It does take a specific bill all the time, but not others. I'm thinking I need to calibrate the head.
-

When your BV accepted and rejected, did the bills go in and out "strongly" without any slop or slip?
If that's the case, I think you do have a different issue, like as you stated, head calibration.
Mine all were slipping a little and would occasionally take a bill if I helped it in. When I replaced the O rings ... all went in strongly and were accepted.
Oh also... when I took mine apart, there was a considerable amount of dust on the inside, where the lens covers are. I blew all that out as well, although that didn't solve my issue... the O rings did.
But it may be a factor in your case?
-
The bills are taken in with "authority." No slippage from what I can tell. I'm going to be getting some calibration paper soon. It's my bottom of the pile spare head, so it's not an emergency, but I just hate to throw anything away if it can be fixed.
-
Where does one get a roller kit for these?

The whole premise of this thread is that the OP had issues with his validator. He went to home depot and bought O rings about the same thickness as the ones in the rollers. He replaced them, and his validators started to work. I did the same, but my validator appears to be a calibration issue.

Where does one get a roller kit for these?
Jason
I don't think such a kit exists, unfortunately. The JCM authorized dealers and repair centers probably have the needed parts on hand for their own use if they do a repair or rebuild, like for a repair under warranty or something.
-
The bills are taken in with "authority." No slippage from what I can tell. I'm going to be getting some calibration paper soon. It's my bottom of the pile spare head, so it's not an emergency, but I just hate to throw anything away if it can be fixed.
Yes I'm glad to hear that... not that yours doesn't work but it tells me that my O ring replacement was exactly my problem. I found more O rings at Ghanal lumber yesterday by accident. I was just there for something else. But this weekend I'll take one of the old O rings and see if I can find a better match for size.
Just before the holiday, I flipped one of my repaired BV machines and inserted every bill in my wallet... about ten of various denominations with one bill being very slot and a bit tattered. The BV took all of them! Soon as I have some time, I'll take one apart again and photograph the sequence and procedure. It's really not that hard other than getting the shaft out. But I think it would be nice to have for others who have this problem, that haven't taken one apart before.
Hmmmm maybe I should make a repair kit? I could mark up the hell of of those 22 cent O rings! :rotfl:

Might find the right size in these;

I have a box and use them on a lot of things.

Well here's a disappointing update on my great O ring fix!
I'm working on someone's Game King with the same issue - WBA 12 with "slipping/sloppy" bill entry.
I decided to just replace his BV temporarily with my "repaired" one. After I installed it, it took some bills then started doing the same damn thing! I lifted the lid and saw that the "new" O rings had rotted after only a year... less than a year actually. :hissyfit:
So now I'd like to find a higher quality O ring for these. I guess I can contact the manufacture. Frustrating that these stupid things just died on me.
-
Nothing so far from the manufacturer but that's understandable.
I guess I need to learn about O ring composition and which ones will not rot or wear out from "bill slide."
If anyone knows about the material the original ones were made of...
I don't even know if this is worth fixing - they seem to be on ebay occasionally, cheap - but you never know if the same thing will happen again. I've seen the problem come up three times recently so it seems worth the effort.
And it was fun to troubleshoot it to the two sets of O rings that initially grab the bill and it was a relatively easy/low cost fix as well. I'd be happy to pay more for decent O rings too. Time to comb the internet.

In the manufacturing industry we used Viton O-Rings. These will withstand high temps, about 600 degrees, volatile oil (very corrosive) and will last for years. You should be able to find them at a Fastenal store as they carry many industrial o-rings and have catalogs to order also. Give these guys a try.....Mark. ;)

S2000s will simply give you a CRC mismatch error, and opening/closing the door will clear that. That wouldn't account for rejection of certain bills. What you should check is what version of firmware is on the bv, which can be done through the game. Is it the same series of 20 and 100, or does it seem to just like older 20s/100s? The latest USA firmware for IGT is 3.80-34. There was one newer version created but it wasn't released for widespread use.
To find the firmware of the bv, hit your test switch, go into accounting/program version and go to the 2nd or 3rd submenu and it'll show you.

Hi Jon
I had actually ruled all that out. The BV was updated (up to current 20's) but was intermittently taking bills. When I replaced the O rings on the rollers, I got 100% bill acceptance. But after one year, the O rings rotted.
