    [Misc] Ir 2520 toner level

    Hi there,
    I have a customer who owns a Canon IR2520. Ran out of toner and i tried to refill an old cartridge but the copier refuses to use an old refiller cartridge. I have three more days left until i receive the new cartridges and thought i might help this particular customer with an old refilled cartridge for a few days.
    Does the C-EXV 33 toner cartridge have some kinda chip somewhere? How does the copier determine toner level/consumption/cartridge EOL before it rejects any?
    This in only for my personal information because i always take care of the copiers i sell and use only genuine cartridges.
    Thanks alot for the info.
    Have a nice day.
Working...
