Come fregare le stampanti HP...

[Igor]

Ho una HP 940c e vorrei evitare che le cartucce rigenerate siano sempre viste come vuote evitando poi il noisoso messaggio di segnalazione.

Qualcuno ci è riuscito?

Ci sono riuscito finalmente...quella guida infatti era sbagliata (metodo 4)..eccco quella giusta:


COLOUR

Lid up.
Colour cartridge out.
Cartridge upright, contacts facing you, tape over the 4 top right vertical
contacts (i.e in a column as it were). Each dot and cross is a contact.
- something like this:
.. . X
.. . X
.. . X
.. . X
.. .
.. .
.. .
.. .
.. .
.. .
.. .
Reinsert Cartridge.
Shut lid and wait 3 seconds before lifting lid.
When cartridge reappears, remove it again.
Remove tape and replace it only covering the 2 top right vertical contacts.
- something like this:
.. . X
.. . X
.. . .
.. . .
.. .
.. .
.. .
.. .
.. .
.. .
.. .
Reinsert Cartridge.
Shut lid and wait 3 seconds before lifting lid.
When cartridge reappears, remove it again.
Remove tape completely, make sure contacts are clean.
Reinsert cartridge.
If successful you will see that the printer thinks you've put a brand new
cartridge in because it will perform a calibration with the blue flashing
lights inside.
Ink status now reads full.

If this doesn't work you may have to tape over different contacts in the
same column, I tried other people's methods and they didn't work with my
colour cartridge. I think something mysterious may be going on here
depending on the signature of the actual cartridge in use..

BLACK

For the black 51645 I've only used the other recommended method of taping
the 4 top left vertical contacts first,

X . .
X . .
X . .
X . .
. .
. .
. .
. .
. .
. .
. .

then the 4 top right vertical contacts,

.. . X
.. . X
.. . X
.. . X
.. .
.. .
.. .
.. .
.. .
.. .
.. .


and then with none covered, following the same procedure as for colour.
