You have one of these multi-function printers in your company’s office? Chances are that your company is using someone’s services for maintenance work and toner supply. Bad news: without these chips, the copier does not/cannot keep track of the number of pages printed (or at least it doesn’t show in Canon’s fleet management tool from what I heard). This means the service contractor doesn’t get to know in time anymore when your printer is low on toner and cannot ship new cartridges to you in advance. You will only notice when it has already run out. Maybe ask for a spare set of toner in advance.
