Bests & Worsts Reviews from Amazon

My complaint isn't with the technical quality of the toner cartridge or the quality of the prints. But the person on here who suggested covering up the two windows on the cartridge to get more life out of it was absolutely correct. My printer stopped working because it was "out of toner," so I ordered a new toner cartridge. After reading the suggestion, I took two pieces of black electrical tape and covered the round windows on either side of the old cartridge. I have since gotten more than 200 perfect prints out of an "empty" printer cartridge. Perfect prints as in NO fading, NO streaks! I am putting my new cartridge on the shelf and waiting to break it out until the print quality on my "empty" cartridge finally starts to deteriorate. Update: 300+ pages on the "empty" toner cartridge and still going strong.
