2 Pack Toner Cartridges Replacement

(See Ammended review below) This is the third Arthur cartridge I've used. I sometimes print in excess of 400 pages a day and I have had great results with these cartridges. The print is clear and crisp and I honestly have found no difference, quality-wise, between it and the Canon cartridge that came with my printer. This is a very good cartridge at a decent price (as compared to Canon's OEM high prices). Also, the pages I have printed do not have a chemical stink as is found with many after-market toner cartridges.I highly recommend it!! AMMENDED ON 03-01-17: Last two cartridges both failed miserably. Both leaked toner onto the edge of the paper AND the toner itself smelled terrible. Obviously these toners were from a different supplier than the first three I used. I tossed them both. The quality is not dependable so I'm changing my 5 star rating to a 2.
