I would guess that it would vary enormously depending on what kind of content was being done (average density?). But there was also no question that the CX drum had a life far greater than the amount of toner in the cartridge. That "problem" was fixed in the SX, by using a much smaller drum, with a shorter drum life. HP did not seem to be very receptive to the concept of refilling their cartridges. "We will pay the postage for you to send it back so that we can "recycle" it, by crushing it and retireving some amount of the raw materials in order to get that cartridge out of availability!" I have no idea even of how many different parameters there are in types of toners, but surely SOMETHING in current availability uses a reasonably compatible toner (toner itself - no chance of cartridge interchangability!)
