Copiers have many different features. You need to decide what features your copier must have before choosing a copier. First, you must decide whether you would like an analog copier or if you would prefer digital. You also need to pick the copier size that will work best. If you have a large office and do large projects which require a very fast copier, you may need a big copy machine. Whereas, if you do not have that kind of space, you may need to consider a personal copier. You will also need to make a choice between a black and white copier or a color copier.
