i'm not using original inks. i have refillable carts since day 1. after 2 months of intensive use i have random cart error on matte black. if i switch matte with photo black the error switches too. sometimes when i reinsert the cart, error is gone, printer ready, but when it starts to print the error is back. even more, sometimes when i reinsert the cart all the carts give the error at the same time. the chip is reseteble, so i don't suspect to be the chip, but rather mechanical, something related to preasure, because error are more frequent after a bussy day. is there any solution to my problem other to pile a stock of new carts?
many thanks,
Adrian
