Saves you your money !!

These cartridges are lowest quality rail, print is not uniform. Especially the black toner print times too bright, even totally dark or equal to both on one side in spite of the same settings. The printer makes since totally ridiculous rattling noises. If you need to print only sketches or lubricating leaves for themselves, they are okay. But if you always want to print official documents, none !! They are annoyed only !!
