Rinsing and bleeding the HP ink cartridge with the ink activator
Applied by instructed person
Apply if, even after wiping the nozzle plate, the print quality does not improve.
Ink cartridges exposed for an extended period may dry up to such an extent that simple
cleaning by wiping is inadequate.
Open ink cartridges subjected to severe shock or shaking may result in air entering the
nozzles. This result an increased nozzle failures during printing or the ink cartridges stop
printing altogether.
In this case, the cartridge nozzles can be rinsed with the ink activator. The ink activator
consists of a holder and a syringe.

Press the ink cartridge in the direction of the arrow until the cartridge is firmly seated in the
holder.
3.

In case of foam formation in the syringe, continue extraction until the ink appears in the
syringe.
5.
Remove the syringe from the holder.
6.
Remove the ink cartridge from the holder.
