IGT S+ Super Joker not registering all coins

[xanadu]

Here is a quick youtube video: http://youtu.be/5z4KjOzzQgU

Only about 50% of the quarters are registering, doesn't seem to matter if they are the old style of newer ones, it is very hit and miss.

What can I adjust to improve this?

On another note, what is the proper term for the sit-down style of slot machines?

Thanks!

From your video I'm going to guess that all the coins are going to the hopper. Well that tells me the comparator is doing a outstanding good job. So the only thing else between the comparator and the hopper is the coin optics.
Just another guess, was this once a large coin machine and was changed to a quarter machine ? If this is correct, check the size of the shim inside the coin optic, the shim must be of a size that will force the coin to the side so it passes between the optics.  Maybe just dirty optics.

It's called a Slant Top.

Ah, good point, yes, the quarters are passing through the coin mechanism and dropping back into the players payout hopper as if they are being rejected as legitimate.

I don't know the history of the machine (ie; used to use large coins, etc) as I just picked it up today from a local Craigslist listing.  The optics on the payout hopper had been broken so once I reassembled things it is mostly working, nice!

I will go check out the coin mech optics to see if I can find anything.

Slant top, got it.

Appreciate the help!

A full tear down and cleaning of the coin optics fixed it right up, 100% success on registering coins now.

I tried just blowing it out with canned air but that didn't do the trick, had to actually wipe off the optics with denatured alcohol.

Thank you!

Your going to get a lot of folks upset by using alcohol. me I just spit on a rag and smear my DNA all over the optics.  Damn it just dawned on me, with some of our members that would be the same as using alcohol !!
