LF: Schematic for HP inkjet printer cartridges

[Kirk]

Yes that's right, HP inkjet printer cartridges. Need to know what the
circuits are on the cartridge from the contacts to the print head. Tried to
meter this out and it's not making much sense of the readings using an ohm
meter.

Need just about any known cartridge that is still in use. Any one or all of
these if anyone can. HP will not give out this information because they don
not want anyone remanufacturing used cartridges.

Are you kidding me?

There is a propietary IC that for the most part consists of several
OP-Amps designed to drive inductive loads. I know this because I
did a metal spin in silicon for a redesign to slightly improve the
performance of a particular cartridge, but beyond that I don't think
your going to have much luck. If you just want a pin definition of
what is on the cartridge itself, then there should be a speck sheet
out there somewhere. If HP is not willing to work with you then
perhaps you can find a third party that has a printer that can use an
HP cartridge. You may have to reverse engineer it from the printer
end rather than from the cartridge, but be warned that there is
probably a good reason why HP is not disclosing information to you.

Need just about any known cartridge that is still in use. Any one or all of
these if anyone can. HP will not give out this information because they don
