OMG copiers are great for components. Especially the bigger ones that have a lot of paper handling i.e. many paper feed trays, document feeder, finisher (stapler). Find a nice big one and you'll find all kinds of motors (steppers, servos, 3-phase DC), solenoids, sensors, clutches, and of course the appropriate components to control them (IC's). Some of the motors are fairly hefty. The components are 24v but naturally there'll be a beefy power supply in the copier to put out all the necessary voltages 24v, 5v, and sometimes others. Lots of wires, connectors, microswitches too.Depending on the machine there'll also be pulleys, belts, gears, bearings, bushings, rollers, shafts, etc.If you go to your local copier dealer I'm willing to bet that at any time they're going to have one or more that they're ready to just throw in the dumpster that they'd be more than happy to give you. I know all this because I have a copier dealership and I've always found it a great shame seeing all that stuff go to waste. Lately I've been trying to harvest as much as I can from them before the scrap guy picks them up, but I have a hard time keeping up.
