One of the things about salvaging parts is that sometimes you salvage a part that you may have to store for a while before it becomes useful. Take apart the printer without damaging any parts and store them. This gives you the experience of learning how the printer was put together and a mental inventory of what you have. After you have a wealth of parts that project that comes to mind will be easier to build since you have a stock pile of "strange" parts that you can draw from. Also now projects will make themselves known. In the meantime get yourself an electronics trainer and start working on the different projects that are in the manual so that you know most of the basics and can get on to the "meatier" portions of the hobby. First rule of salvage - never throw anything away. It's guaranteed that if you do, you'll need it at least 2 times in the next week. Good luck.
