Originally ordered 4 cartridges, one of each color.
The black cartridge ran out of toner showing 90% left.
Shortly after that, the magenta cartridge froze. There is a small white cog that is driven by the printer and it totally locked up with 97% left on the toner. It could have damaged the printer and I stopped using it until replacements were received.
I received replacement black and magenta cartridges. However, the magenta ink was so bright in color that it made all color printing that uses magenta to show toward purple. Since I don't print photos, I decided to just use the magenta cartridge and put up with the weird colors.
At 75% toner left on the magenta replacement cartridge, it started dumping excessive amounts of toner making streaks all over a printed page.
I have to clean up the internal parts of the printer after every single sheet is now printed.
Really, really bad quality control.
