Hi,

I have got a HP Deskjet 600 printer recently.
The original (and the replacement) black only cartridge has on the
back a strip of plastic with a printed circuit in it, it makes contact
to buttons in the housing when mounted.

Under the cartridge the plastic extends too, there is a recktangular
strip with 2 fine lines visible.
Are these lines the 'jets' where the ink is coming out when printing??

In the plastic bottom of the cartidge I find a small (0.5 mm) hole..

As I got a replacement cartridge from a non HP brand (refilled), which
has such a hole in the bottom too, but which also has a hole in the
top (closed by a plastic plug - I ***ume the cartridge was refilled by
making this hole, injecting the ink and closing by the plug).

I took the plug out and replaced it immediately again.
After this, I noticed ink coming out of the small hole in the bottom..
It kept seeping ink, that's why I let the cartridge a few hours upside
down on the table..
My idea: air coming in after unplugging would force the ink out of the
opening in the botoom; after standing upside down for a while air
might escape and no longer force ink out in upright position..

Is this true??

Hope you can answer on 'jets' and 'ink forced out' themes...

Yes, these are the jets.

This cartridge needs some slight vacuum inside for not leaking. Blow some
air in the top white hole, till the cartridge drops about 20 drops of ink.
