Coin Door Adjustment

[commandcom]

Hi,

I've got these coin mechs that refuse to accept a US quarter.  I've attached a couple of images of one.

When a quarter is placed into the mech, it gets dumped immediately into the coin return.

I did some poking around the forums and it seems white nylon screw is how the mech is adjusted.  I tried setting this screw to many different positions, but to no avail.

Is there something else I'm missing?

That's a Coin Controls coin chute. Leave the white plastic screw alone. The only adjustments you need to be concerned with are that hex headed gold screw which adjusts how close-far away the magnet frame is to the main plate (coin thickness). There's also a "kicker" adjustment on the backside of the main plate. You didn't provide a picture of the back of this coin chute.

I did fiddle with the gold-colored screw.  With the screw turned all the way in, or out, the coin is still rejected.  What role does the cam-like device play?  It look like it should grab the coin and redirect into the "accepted" path.  With these doors, the coin never even touches teh cam.

I did not think there was anything worth looking at on the back.  Here's what it looks like.

if coin falls right thru that means that the coin cradle is to big for that coin. The coin cradle must swing along with the coin.

The lable on that says (I think) 25c but maybe someone change the coin cradle to accept bigger size coin than a quarter size.



If you can't find a fix, I have the exact replacements for quarter size. PM me if interested.

That white plastic screw sets the 'fine' coin diameter adjustment. It looks like the kicker on the backside is out of adjustment.

Sometimes these late model Coin Controls chutes develop a crack or break in the plastic hinge causing the gate to sag slightly. This causes jamming or rejecting. The only cure is to replace the entire plastic gate (which is not available anymore brand new).

Remember that the cradle must pivot quickly and easily. Never ever use WD-40 on these.

If I manually feed a quarter into the cradle, the coin does get accepted (i.e. falls though onto the switch).  The cradle fits the quarter snugly, so I don't think the cradle has been replaced/modified to accept another denomination or token, (this theory is further supported by the coin door's reject buttons which display .25 cents).  The cradle does move freely and easily.

I inspected the plastic hinge; it appears to be in good working order.  No sagging or cracking found.

The root of the problem seems to be that the quarters are getting rejected even before the cradle has a chance to evaluate them.  Adjusting the "kicker" (is this the manual coin reject?) was mentioned.  How is this accomplished?  Aside from the aforementioned brass and nylon screws, I don't see any other obvious place to place to make adjustments of any type.

Thanks for your help.

there are 2 spots where coin get rejected. Which one is the coin falling from ? The front or the back ?

If it falls on the front, coin inserted is smaller and rejects it thru the front hole or coin got stuck (sits on the cradle) and when the reject button is pushed it also falls to the front hole.

Now if the quarter is falling in the back part, then you need to adjust the kicker (its located on the bottom with a screw on the back, not the reject button). If you coin mech is attach, take it off you can see it.

Perplexing.  Even with the mech off I do not see anything that looks it could be adjusted.  Could the kicker be missing, or is in integral part of the coin mechanism? (as this is my first coin door, so I have no idea as to what may or may not be missing) 

At any rate, the coin always falls through the front hole.  The only time I have seen the cradle catch a quarter is when I manually guide a quarter into it.  So maybe the original hypothesis is correct: the cradle has been modified to accept a different type of denomination (Canadian perhaps?  If I can find one I'll try it out).  Is there a way to tell if the cradle has been swapped (i.e. measuring the opening between the two arms)?

Thanks again
