Easy installation, you only unscrew one screw.
You install it on the printer when it gives you a message to replace the maintenance box.

Sometimes it may display on the screen that it doesn't recognize it, you take it out and put it back in 2-3 times and it's okay. I got scared the first time it told me it didn't recognize it.

Easy to install but mainly much cheaper compared to toner printer kits. Also, compared to printers that use cartridges, you can do the maintenance yourself since the sponge is not inside the head. As for the frequency of replacement, every four to five refills approximately requires one, although I don't think about it whenever it gives me the low price message.

It has a chip, so anyone can change it themselves at a low cost, without needing to take the printer to the service. Only a screwdriver is needed and the instructions displayed by the printer when the previous maintenance box reaches its end.
