Printer ink problem

Hi,
I've found a problem using the printer of EPSON. The attached is the ink of the printer. There is a small circuit board which looks like a sim card. It is an indicator of quantity of the ink being used. The printer will count approximately how much the ink is left. My problem is, when the monitor shows that there is no ink anymore, the printer stop printing, even there is 1/4 to 1/3 of ink left.
i've found the boss of a computer shop own a device that can reset the small circuit board, so the monitor will show 'full', until u finish using the ink. But he refused to tell me where to buy it or how to make it. Because he uses that for earning money. So, can anyone help me to solve this problem? Maybe the way to reset it. That is very wasteful if there is ink inside and u throw it away. Thanks..

Epson has a class action case against them, might want to google for it. They tell users the ink it done with 20% left in the cartrige. I think they are giving $45 for online spending if you fill out there form. I have many epsons and did not do it. But $45 will buy some ink. On the little unit you are looking for

i know that reseter.. but can i reset using software without removing the ink? Straight away from the computer. Is it possible?
