Addendum to my original review: I do not use this printer much. After a few hundred pages with this toner cartridge, the print quality began to deteriorate. The print wasn't as dark and the pages came out with a grainy gray cast. Cleaning the printer with compressed air did not help. I installed the original OEM toner cartridge and everything is back to normal. . . very sharp and clear. I used to be disappointed with aftermarket toner in other printers. Based on other reviews I was hoping this one would be better. It's not like this. Now I use OEM toner. First rating based on first impression: The toner cartridge makes a well-made and well-packaged impression. Fits my printer with no problems. The print quality is quite good, very sharp and clear. The print may not be as dark as OEM toners, but it's hard to tell. In any case, the printing performance is excellent. I would be willing to buy another one.
