Yellow ink message on Photosmart C51180 All-In-One

have the same problem, do not know what to do

i purchase my c5180 from my Friend, yes had the same problem before, tried to buy a replacement ink and yes it didn't work the way it should be, so i tried to refill the old original ink by using 2 pcs. basketball pin and 1 syringe..one pin i've attached to the tip of the syringe replacing the needle,.. the ink cartridge has 2 holes put onee pin into hole no.1,doesn't matter what hole it would be, and then put the right ink color unto the syringe ex. yellow, and then insert it to the hole and gently inject the ink until it comes out on th other pin...it works...but still you will have a question mark on your ink level...
