help...officejet pro k850, hp13 (ARC)auto reset chips not working

[kamotekyu2]

my cartridge is hp 13, and my new printer is officejet pro k850, i purchased the http://www.macroenter.com/ProductDetails.asp?ProductCode=IA-11-4837AB, auto reset chip and bulk refillable cartridge but to my surprise the ink indicator is still blinking when i put the cartridges in the printer, and the ink monitor says that cartridges are empty and need to be replaced. i have turn the printer off and turn it on again but still blinking afterwards and tried it so many times hoping that the chip will rest but no avail. according to the company where i bought the refillable cart. and ARC, that the said ARC is mainly used for HP 10, HP 12, and HP 13 compatible printers. i am desperate to know what kind of ARC will work for my printer, is there anybody here who used a CISS with this kind of printer?

I've discovered a seller on ebay with compatible chips for the L7680 but with a twist explained here:
