Jamex Coinbox Not Accepting Coins

One of the most used services in the library, I’m talking Top 3 here, is our printing/copying services. And in the omni-budget-strapped world, it’s also a steady source of revenue. Not huge, mind you, but every little bit helps. So you can imagine the consternation when something happens to the Coinbox from which this revenue comes.

Most of the time, the problem is a discrepancy betwixt the physical count of coins and the count of coins in the software. In these cases, zeroing the tubes takes care of things. This is a little tricky, but the user manual does a good job of documenting that process. So I’m not getting into that here.

What I am getting into is when the zeroing doesn’t work. In these cased the most likely culprit is a jam in the coin chute. The coin chute lives behind the tubes and is where the coin is redirected if that particular denomination’s tube is full. The chute then sends the coin to the drawer below the tubes and accepts the deposit, thus allowing the patron to print (or copy).

If multiple coins are dropped too fast, and their tube(s) is full, that can contract what The Simpsons called “Three Stooges Syndrome”; that is the coins try to use the tube at the same time and get stuck. When this happens, any future coins are rejects and sent to the coin return try and the patron can’t print. So here’s the procedure to clear said chute.

1.) Open the back door

2.) Disconnect the power cable on the door


3.) Push up the coin return plunger

4.) Push the acceptor lever down


5.) Pull the acceptor towards you. This isn’t as simple as it sounds. So if, at first you don’t succeed, try, try again.

6.) Remove the acceptor ribbon


7.) Look in the chute behind the quarter tube.


8.) If there are any coins in reach, use needle nose pliers to snag them. If you’re not “blessed” with sausage fingers and can snag them that way, by all means, have at it.


9.) Once the reachable coins are removed, shove a thin metal strip down the chute and wiggle until you ear the clinking of coins in the tray. The strip in the picture below comes from the back of a desktop. They are placeholders to keep foreign objects off the motherboard. You remove them when you expand the PC by way of new graphic cards, another ethernet adapters, etc. You may not have access to one of these. If not, perhaps a pair of scissors would work. Just take care not to run with them. My mom said that was a bad idea.


Once all the coins clatter into the drawer you can do the following:

10.) Reconnect the power cable

11.) Close (and lock) the door

And that’s it! Usually.


Sometimes that doesn’t work. When it doesn’t you have to remove the coin tubes and clear any coins stuck under there.

12.) Open the Coin Tube Door

13.) Grab the top of the Quarter Tube and pull straight up. 

Make sure to cup your hand under the tube because there’s no bottom and as you pull the tube up, the coins will spill out.

14.) Repeat with the Nickles, Dimes, and Dollars.

You’ll see two projections that slide into two groves. When you want to put the tubes back in, make sure to line these up or the tubes won’t fit.

15.) Push any stuck coins out of the way.

16.) Put everything back together and you should be good to go!
