I do not question the quality of printing. The toner itself is a good product. By cons, after buying a new printer, I quickly change the toner. I first thought to have made the 1,000 prints or copies, as is written on the box. After changing the second toner quickly, I'm really demandéa me if I printed réelement 1000 pages. So I did the test using a single ream 500 sheet to check the number of prints. Just arrived to 500 sheets, a message tells me that we must change the toner. I made this experience troia times. It is clear that the toner allows me printing or copying of only 500 pages, half annonée Brother
