Thus, the cartridge can function at all, you have to switch off the warning light on the Canon printer. Only then insert the cartridge. She is also recognized. If they are used before, it is not recognized by my printer because apparently the old cartridge is still active. If you stick to it, the ink cartridge works without problems. There is a refill cartridge, the print quality is accordingly poor, than a new original cartridge. Who needs the best print quality, must be upheld better the expensive original. But the difference is minimal, so me personally, is in the documents that I print matter. Since the cartridge is working properly and is very reasonably priced, I am satisfied with the result. On a level indicator will be without one, which does not matter in a printer which uses only two cartridges anyway. The old cartridge must not be disposed of with household waste you. It is the package attached a mailer that allows you free can return the old toner cartridge to Pelikan - very useful.
