Works just like the OEM toner. No errors or other incompatibilities. Color is dark, homogenous black.
This, together with a cable, was my first order from MonoPrice. Search and filter features work well. Website is generally free of annoying distractions and advertisements (though my setup may also be doing the trick). No hassle ordering. Shipping was as expected. Brings back memories of the old Newegg before it got too popular.
This product is doing just what is is made to do. It was delivered when they said it would be delivered and I would and have recommend Monoprice to others. I also have a different printer at home and have been very satisfied with the life and print of that toner as well.
PROS: The Printer works great as soon as toner is installed. This is used in a small busy office and the price of the toner is 1/3 less than what we were paying.
