Copy machines are kind of expensive, so there is no problem if businesses will resort to buying second had or used copier machines. However, how do we know if the machine we will be getting is a lemon? We do not need to drag along a technician with us every time we shop for a copy machine (though that would be a good idea). But when buying a second hand copier machine, we should always look into the condition of the gadget and check how many documents it had already copied to see if its use had been abused. This can be detected from the counter usually located near the controls, if not inside the machine. People should always be on guard for copier machines which are literally being sold for a song because with all probability, the seller is hiding something. So in buying a used copier machine, we have to be extra vigilant before making the purchase.
