Recently one of our blog readers raised this question that there are some errors when buying a used slot machine. Though his query was related to his IGT Double Diamond model 96435800 reel slot machine which he had bought but here we are catering to some of the most common errors buyers face when they buy a real slot machine specially a refurbished ones. You can try to fix these errors by doing the following actions as given against each error. Also there are many superb videos online that teach you how to fix these errors.

EEPROM Device Error

EEPROM (electrically erasable programmable read-only memory) is user-modifiable read-only memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application of higher than normal electrical voltage. Unlike EPROM chips, EEPROMs do not need to be removed from the computer to be modified. However, an EEPROM chip has to be erased and reprogrammed in its entirety, not selectively. It also has a limited life – that is, the number of times it can be reprogrammed is limited to tens or hundreds of thousands of times. In an EEPROM that is frequently reprogrammed while the computer is in use, the life of the EEPROM can be an important design consideration.

A special form of EEPROM is flash memory, which uses normal PC voltages for erasure and reprogramming.

Here is the video how to fix this error

Error on door of slot machine

Many times when the display on the door indicates an error condition, open and close the door to reset the game and clear the error. Open the main door which clears the current game information and a “0” appears in the Coins Played window. Closing the door resets the game and the reels will spin and stop in their last valid position. The error code should clear and the digital display returns to normal game play.

Error Code 12 Battery Voltage

To fix this error turn power off and then turn power on if the battery voltage has dropped below 2.9 V. Also replace ASAP due to possible RAM (Memory) corruption. Open / close door to clear and also Replace 3.6 V Lithium battery on CPU board.

Coin Errors

For coin errors see that comparitor is seated in all four acceptor clips and that acceptor does not have coin(s) jammed or the coin optics below comparitor is not blocked You can ensure toggle power switch is in activated position if installed.

Coin Out Tilt Hopper

Check for and clear any jammed coins in the coin out channel. Also see that the coins are not jammed behind hopper knife or see that the coin out optic sensor is not blocked by dust. If so you can replace hopper coin out optic.

Error in Extra Coin Out Hopper

To fix this see that the hopper motor brake functions properly. Check the coin wiper/ knife for jams and if so adjust them if necessary.

Hopper Empty Error

This is the most common error that new slot machine owners will have because the cash out button was pushed and the number of coins in the hopper is less than the total credits to be paid out. You can open the main door and check the hopper for coin level (your hopper will not dispense all of the coins), refill and close the main door. You may have to do this several times for all of the credits to be paid out.

Reel Tilt Errors

You will find that there are reel tilt errors and for this see that whether the designated reel is misaligned or malfunctioning. Also check if the reel is not unplugged. You can switch connectors from one reel to another, determine if error follows change of connectors. Try replacing reel assembly or optics if error stays with bad reel. Also clear Ram and see if it works again.

Error Codes and Fixes

During the process of clearing error codes, you may encounter multiple 6x series errors. Here are few common ones and their fixes

CMOS RAM Error

This means Bad (or cleared) CMOS RAM data You can Press test button 3 seconds Error code 61-1 should now be displayed. Now close door, turn and release reset key once. Same for game data reset.

Bad Game EPROM or Data EPROM Error

Printed Circuit Board Machine

Check circuit board and replace Game EPROM. For Data EPROM error check circuit board and replace Reel EPROM

Bad EPROM Device or Bad EPROM Data or Game Type Mismatch

Press self test switch for 3 seconds If error will not clear replace EPROM Also if the processor could not read or write to the named chip Press test button for 3 seconds Error code clears from display.

Most of the errors can be resolved with little help but many need technical knowledge. Remember that if you are on a warranty or not the place or online site where you purchased a used slot machine is there to assist you with trouble shooting and repairs. They can guide you over the phone or send some mechanical and technical person to do so.

Slot Machines have been a part of the gambling world for many years now. In the early years, slot machines where thought of as a novelty, or something to keep the wife busy while the real games were played. All this began to change in the 1960’s, when slot machines began to rise in popularity. By the early 1980’s slot machines began to account for as much as half of a casino’s income. At the present, slot machines clearly rule when it comes to gambling. Casino slot machines can account for as much as 70 to 80 percent of wagering done.
I cannot include every machine ever made as it would not fit in this book. The main games I will cover are the Players-Edge Plus and the Slot-Plus. These games were produced by IGT (International Gaming Technology) and are some of the most popular games ever made. IGT games by far-out number any other slot machine manufacture. Most casinos have 50 to 80 percent of their slot floors filled with IGT games. For this reason I have chosen the Players-Edge Plus and Slot-Plus games to explain slot machine repair.
If you need to fix a different type of game, the same theory will still apply. Certain things will be different, such as error codes and the games software. But much as in the way automobile manufacturers are different, there is still the same basic theory applied in way that they operate.
All slot machine manufacturers provide manuals for each slot machine they produce. These manuals appear cryptic, but provide a wealth of information. If you are working in a casino, the manuals for each slot machine are usually provided. If you are at home however, and don’t have your slot machine’s manual, try to acquire one. You can do this by contacting the manufacture or a local slot shop. (I have set up a site to download the S-Plus or PE-Plus manuals at http://www.npgcable.com/~aranger )

What Kind of Machine Do You Have?
There are three types of cabinet; the UPRIGHT, the SLANT-TOP and the BAR-TOP. The upright games are the most common cabinets and simply sit upright. The slant-top games are games that lean out in the middle (you can set things on a slant-top as you play them). Bar-top games are made to slide into a pre made cabinet at a bar so they will be flat and small.
The main identification on slot machines is a serial tag located on the outside of the machine. On upright games, the tag is located on the lower right-hand side. For slant-top games it will be located below the armrest on the right hand side. And bar-top games the front right hand side. The serial tag should have the manufacture, serial number, date made and the model number.
Slot Machine Basics
Slot machines took a huge leap forward in the late 1970’s with the invention of microelectronics, up until then, all slot machines where entirely mechanical or electro- mechanical. With the use of microelectronics, the video poker game was born, along with much more efficient slot-reel games. The old mechanical games used all kinds of springs, levers and gears to carry out its functions.
With microelectronics, almost all of these functions are placed on a single circuit board. There are several circuit boards in modern slot machines, but one circuit board stands out as the most important. This board is called the MPU (Main Processing Unit).
