How we put a value on your old copier
Four things matter most: what model it is and its age, the page count, the shape it is in, and whether it still runs. A copier with only a few years on it can make a real dent in the cost of its replacement.
Machines at the end of their working days still have parts that keep other copiers going, so even an old one can be worth a little towards the upgrade. Just mention it when you ask about the new machine.
