I have used several different toner cartridges after the sale. All cartridges were replaced last week. I would estimate that they will all be around 80-90% levels. Less than 100 cyan pages are 10%. I've never run out of toner so quickly. Let's see what the support says. You cannot replace one of the cartridges. You will only return one cartridge or all 4. So you need to order a replacement.
