    Canon 8350cdn Check Black Cartridge message but toner level says OK

    I am still using the starter cartridges on this. The printer count says 289 for the black cartridge and the toner level says OK for all, but I am getting an message on the display "check black cartridge". It is printing fine after I click OK to clear the message. I hate to buy an expensive new toner cartridge if there is another issue causing this to happen.

    contacts may need cleaning -(alcohol -very damp cloth)
    remove ink black cartridge-you will see metal connectors on the cartridge
    look in & check interior contacts


    be careful> u don't want static charges from your person on contacts

        That's what I thought, too, but it didn't help.

          I cleaned the interior contact that I could get at without removing the toner tray because I don't know how to remove the tray.

          I have the repair manual, but I am hesitant about getting in over my head.
