Epson Chipped Cartridges

I was just wondering if anybody knows how to reset the chip on an Epson T040
cartridge without buying a reset device. Alternatively, if anyone just knows
any way to wire up the printer so that it always thinks there is a full
cartridge in the slot, that'd be good too.

Just how complex are the chips? Do they send out a coded signal, or is it
just a case of some contacts being on/off?

It's just an EEPROM memory chip, so you have to either reset the chip,
using either PC software, or an external resetter. If you want to fool
the printer, you need a microcontroller to emulate an always full
chip.
 
Amazing, there are allways full chips in the market.

No, you have to get a microcontroller, and upload executable code to
it, and build it onto a PCB which you isntall in your printer.
 
There are a number of misconceptions and errors in the two letters.

I would love to have been a fly on the wall when Epson "convinced" the
Dutch Consumer Associations the "error of their ways" ;-).
