.While I went through all of this and feel like it should work, when I use the scanner and scan over the 'a,' it keeps reading the 'a' value over and over, not running the motor. Thank you for your help. If you have any other suggestions, feel free to offer them, but if not we might just go with the code I posted in the original post. Again, thanks for the input you gave, as you took the time to give us some very solid suggestions.Our main problem, and why we are trying to control the speed is due to the fact our conveyor belt is not endless. It has this sort of configuration, so it catches on our shafts.

Might just be not enough torque with the motor (NEMA 23), but it seems to be fine when we use a different code at a certain speed; we just can't stop it. Servo MotorWorking of stepper motor in scanner? A flat-bed scanner works by using a motor that moves the scanning head across the paper laid on the glass bed of the scanner? Text is best done on a.We will keep toying around with it! Stepper Motor Drivers And ControllersOkay, were not sure if Every single Scanner does this, but it's been our experience that all of our Lexmark Scanners have had 3 color LED lights. Which means, you can create all the colors in the spectrum:)To get the Scanner open you need to remove 4 hidden screws from the bottom of the Scanner, they are underneath the small rubber legs.

A smooth belt on a smooth pulley will slip. And you don't want that. Timing belts aren't as precise as a good set of gears, but they are much easier to set up, and if you go with a belt with many ribs per unit length.
Once you remove them, the scanner easily comes apart.The first thing to take apart is the Top lid Cover, a little tug on both ends should get this released.Next is the Top layer that protects the whole interior workings of the scanner, remove this one carefully as it might have the glass sticking on one side with adhesive, just enough adhesive to move it when it moves but not enough to keep in place. (if you're not careful the glass will fall from the lid and break)Next remove the Glass from the top of the scanner. Save this, you can do a small Penny Hockey Table with it.
Place the Glass back on the upper container, modify the container a little, then make some slits on the goal posts and play with a penny. Add some obstacles etc.Just a small idea.
We found a small 4 switch button fro an old computer. Each one of the terminals will control one light. We also added a 9 volt battery which works great.However we had a better idea, instead of using a small 4 switch - switch. You can use potentiometers that allow you have more control over the lighting system so if you make one of these, use potentiometers they have a way better effect:)We placed everything on a small bread board following simple Switch circuits. I.e. Drivers license barcode data format. The power outlet for the light, goes to a battery positive terminal, the negative terminal goes to the switch, the other end of the switch goes to the Blue light. And so on until all the lights are connected following the same pattern.Finally what we did was connected all the cables on a small piece of bread board and soldered all of our connections together. We added a 9 volt battery connection and attached the board to our work table when we found our perfect light.We went for a soft Red light, something that was not going to waste our battery life to fast as this was going to remain on all night so our dog didn't bump into things if it accidentally found it's way on the work shop.
Like it usually does.We hope you guys enjoyed this instructable, keep in mind you can always go modify this thing, by adding the potentiometers, or even placing it inside a small wooden box.HM-Innovations.
