We have several Canon iR-ADV C5255 printers in my office with about 1,000,000 impressions apiece. Canon is telling us that we need to replace the printers now, but I have heard of laser printers with 4,000,000 impressions or more that are still in good working condition. Does anyone have any experience with this kind of printer? How many impressions can we realistically expect? Should we replace our machines now, or maybe swap them out for less-used printers in other areas of the building?
