Levels of inflating or defalting the air bag in HP Printheads

[repro]

Hi All,

I am a little stuck and wondered if you could help me.

I have cleaned my HP printhead and refilled with ink and sealed with the ball bearing, however I am getting nozzle leak and i think this is because the air bag (Bladder) inside the head probably needs deflating to create a vacuum, does anyone have any knowledge of what i should be doing please?

Regards

I take it you are talking about the pork chop shaped HP cartridge? HP45, HP15 ??

Did you refill with this method?.......

If so make sure the ball bearing is sealed tight, you may put a piece of black electrical tape over the ball bearing to help with the seal. If the cartridge is sealed properly, and still leaks, then I would suspect it is overfilled, and needs to equalize. Sit it on paper towels, or let it drip till it stops leaking out the head.

I use the clipon refilling method, this makes refilling much easier.

The seal is fine around the bearing, the ink leaks out of the nozzles.

Hmm, is the leak constant? It should vent and stop by itself if it is pressure problem

I can only recommend to look for some jig, through which you could suck out air from the bag. It also helps to clean nozzles nicely...
