Pros: - None

Cons: - Does not work despite "matching" part numbers

Overall Review: I ordered this to replace the toner in my printer. I matched the serial numbers and made my order expecting it to work right out of the box. My printer refuses to accept the new toner. It knows that something is plugged into the socket, but says that it is faulty.

Pros: Good price.

Cons: Doesn't work in my Lexmark CS410DN printer. I get an error 32.52 "Replace Unsupported Black Cartridge." I upgraded the firmware in the printer, but the problem remains. The previous cartridge clears the error, but is out of toner, so I can't print. This is clearly a problem with the cartridge.

Overall Review: When the printer messaged that the black cartridge was low, I order a new one. Unfortunately, that put me outside the return window, so I'm stuck with a cartridge I can't use.
