controling inkjet cartige

[hananl]

Hello,
Might someone happen to know a way to control the inkjet cartige with
pulse signals instead of the computer?
I want to be able to "shoot" ink droplets from all the nozzles at the
same time. I need to know how to operate each of the pizo crystals, and
then to operate them all.
I guess I can measure the electrical signal coming from the contacts
that match up with the ones on the cartridge, but always much easier,
if someone already has that information...
Thanks,
Hanan.

suggest you examine patents granted to HP, Epson, etc.

HP and Canon use the same system, where they boil in the ink in the
print-head to eject a droplet. IIRR the patents were issued to HP.

The printing head including the short-lived heating resistors are part
of the ireplaceablr nk cartridge

Epson do use piezo-electric crystals to generate the ink-droplets, but
the patents belong to a Cambridge (U.K.) firm - one of the many that
didn't give me a job. Intellectually it was probably one more spin-off
of Cambridge Consultants, who did a lot of work on ink-jet printing in
the 1970's. Domino is a better known example.

I went for a job once where the 'we regret' letter
got home before me.
