first i didnt start anything
i didnt say falp your mouth, prehaps you should check it out
anyway i wont enter a debit of who started what first as if i am 12 years old.
maybe we should leave all that behind
cartridge testers are so common in the inkjet refill industry where i am deep into for 5 years now.
companies like
www.cbr-sme.com and
www.oliser.com and many many others make these devices where you can place the cartridge and it will print a pattern to see if all nozzles are working or not
offcourse hp or epson wont give you anything and wont even answer anything regarding this, the only case they did this with parallex was for a cartridge that is about 15 years old technology if not more, so they are not really reveling something important.
i was thinking of who can i record signals coming from the printer to the cartridge and save it in some kind of a buffer or so and then resend it again.
reverse enginnering to know everything is ipossible, hp uses their own mcu, and ics, so you dont know actually what is going on.
also the cartridges are mainly resistors network.
i just dont know where to start or what hould i use to monitor all of these pins at the same time and monitor the signals at real time for them all.
if i could "do it" i would nt be here in the first place
