Pick one up had problem leaving marks on paper, black. Clean base of printhead alot of black ink. Check ink pad where the ink suppose to go into and absorbe through sponge the falls into waste box where ink is saved.try several times asborbing the ink on to kitchen towel,and fill the pad with isopropanol alchohol using a syringe and needle.but unable to unblock pipes. Waste box is easy to do,how do i remove the square ink pad with wire patern. the side rear tube has come off,but need to get to the main centre tube to clear the blockage, Underwise every time the printer cleans the printerhead, there is full amount of ink waiting to be pick up by the printer head...seen a video but only shows photos of the part,
