Also you may notice that it will print fine one day and the next day it won't print until you do a series of head cleanings. Sound familiar?
Gravity refilling is a simple procedure and I will explain how to do is in a minute. Cartridges best suited to the gravity method are those with a primarily sponge filled interior. Examples are HP C6578, HP C1823, HP C6657, HP C8728 Cheap Patrick Kane Shirt , HP 51649A, Lexmark 18L0042, 12A1970, 12A1980 and most Epson Cartridges.
