This colour multifunction laser printer seems to working well. However the driver suggests I change the belt, fuser, and PF wire as they are at the end of their life. Replacement parts cost a total of about $300, much greater than the value of a 5+ year old printer. This is perhaps why it was so cheap to buy used! I wonder what risk I am taking by ignoring these warnings, or if there are some cheap simple solutions. A factory reset may remove warnings, but I assume they are there for a reason.
