Universal Cleaning Solution for HP Printheads box-080840 Upper Right Support with SheetA few considerations: If a printhead has been starved of ink for a long time, it may have burned itself out by printing with air instead of ink. If this is the case, that printhead will not recover with the installation of new seals. Even if a printhead has been starved for only a short period, if the internal ink diaphragm has deflated too much, it will sometimes not allow ink to re inflate it, and the printhead will remain permanently starved.
