Hello,
I specifically bought an Epson Printer (ET-2830) with a Waste ink cassette (Maintanance Box) so I can replace the waste ink packs quite convenient. (Without needing to resort to sketchy programs resetting the waste ink counter)
I even bought some chinese replacement chips, so I can just replace the sponges inside the Cassette (C12C934461) instead of buying the replacements.
Now I have a set of 10 chips that should last me the lifetime of the printer.
But I had this idea to just set the Chip to Write Protected and it just never counts upwards, then I just dispose off the waste ink with a hose into an transparent tank outside the printer.
I have attached an image of the chips I bought.
I cant seem to find any datasheet based on the markings on the chips. (They are all different)
Is there a possiblity that I can just ground one of these pins and it never counts up? (To set it to write protected)
Or is that a naive assumption?
Is that chip an eeprom?
Could reading out the eeprom and the reseting it everytime automatically with an esp or such be also an option?
Ive read about a person that reverse engineered a canon waste ink chip, and was able to reset them.
Thanks in advance for anyone whos looking into this.
