Hi. My ultra shitty multi-functional Epson CX5600 is about to die, I had MANY problems 'cause I didn't know It's original catridges cannot be refilled. Now I'm after a HP F4280 model that uses HP60 catridges and as far as I know the original catridges can be refilled (in my own experience using older models, just take off the top stick of the catridge), but I dunno If It happens the same with this ones. Help please, the fact of the catrifges can be refilled is CRUCIAL to buy the model. Thanx.
