SOURCE: I refilled HP 88 cartridge but printer (Officejet

Under the cartridge is a black like pump - on a new cartridge this is hard and rests firmly on an area inside your printer. As you print, the pump becomes softer - this is how the printer determines it is empty. Once refilled, the pump does not get back to the original state. Open the bottom of the cartridge and put a firm solid piece of folded paper in there - make sure it is steady and re-close cartridge. It will now read as full but may also show full - judge ink levels by the quality of print. Also make sure chip has not expired.
