Hi there, no these aren't correct, they're actually for HP printers. Are you sure your model number is correct? There doesn't seem to be a Lexmark C3226 printer. Could it be the Lexmark C3326dw printer? If so, then the cartridge would be these: https://www.tonergiant.co.uk/model/Lexmark-C3326dw-toner-cartridges/
If you double check your printer model, I can confirm for you.
