I am not getting anywhere close to 3,000 copies with these refilled cartridges compared to what I was able to get with my HP printer. Could be the Dell uses more, but then the 3,000 copy isn't factual. I may have to go back to the Dell toner cartridge...hate the price but this is costing me even more. Is there a 7,000 copy cartridge? I have used 8 cartridges in 4 months.
