PROS: Have purchased these cartridges before and been very happy. Good product at a good price.
CONS: This cartridge doesn't work. When I inserted this cartridge in the printer it failed to print. I rceived and error on the printer "LSU error". Placing the old cartridge back in the printer and I can print again....of course the toner is weak and printing is light and streaked. I cleaned the printer inside and out and tried again with the new cartridge but still have the same error
