Hi Dana- I have the Epson 4800 Stylus Pro into which I installed your reusable cartridges and inks last year. When I power up, I get a flashing notice to reset #6 cartridge.I did just that with your chip setter #ACC-RESETTER-LF. I got the blinking red light about 4 times and it then turned green. However, the display still says to reset #6. Yesterday, the display said to reset #7 and #8 and when I removed and reinserted each cartridge, the display said to reset #6 and#7 and each time I removed the cartridges and reinserted them #6 7 or 8 were said to be reset. I reset all three cartridges but a reset notice still comes on. I have the original set of Epson 110 cartridges which I inserted into 6,7,and 8 slots and the only notice that came on was that #6 was empty of ink. Now,is it possible that the chips on #6 7 and 8 are faulty although they are just a year old and I do not print that much? Also, should I try to remove and place the chips on the original Epson 110 cartridges and place them on your 220 cartridges? After I receive your response and solve this problem, I will then address my clogging problems.
