HI all I have a plotter Canon W6200 that sometimes force me to substitute the maintenance cartridge. THis cartridge collect the ink that is expelled during print head cleanliness. Seeing that it happens a few to often, one times every two months, i was arguing if there was a wy to recover this cartridge without changing it, perhaps emptying it or resetting its chip. Has someone of you experience at regard or different purchase options? Thank you
