I'm a young 74 and like to think of myself as more computer savvy than most of my friends. I like to keep my tech working as long as possible as I don't like unnecessary waste, and particularly despise built in obsolescence. I'll have a few goes at trying to fix things before I give up.
Hello Reza I just bought a printhead (QY6-0042) on aliexpress en I did readout the eepromdata before I put it in the printer IX5000.
After that I put the printhead in the printer and IT WORKS !!.
In the attach files I put the hexdump of this printhead .
It is a long time ago but perhaps someone may need this information.
