I ordered the cartridges in question and the next day my Canon MP520 printer started putting me about the cartridge message. So I made a cleaning and the result was perfect.
But two days later, finished, the printer did not work (message: it is not the correct printing or missing print head head).
So I check impresssion head and I realized that the new cartridge had entered the printer. I wanted to put an old cartridge Pelikan but it was too late.
Result: it cost me a new printer !!!
On the economy, we can do better, they are cartridges that cost me in the end really expensive !!!
Clearly, for the welfare of your printer, go your way!
