back then they was not a problem with refill but now ink is coming from across seas especially with refilliable catridges and to refill a manufactures ink cartridge the reason that dont work well cause when you do recycle ink cartridges they change the stuff thats in the cartridge and put in ultra assorbant in other words refills are not what they use to be and come on dig in them pockets and pay a little more for new ink cartridges cause you cant beat the printing you get and ink last twice as long, but when you use refillable you cut your luck
My wife & I have used generic cartridges & have also used bulk ink & filled our own for some time with several models of printers without difficultly. We have found that we get "fuzzy" print if we refill a generic cartridge or if we try to refill a manufacturer's cartridge more than twice (sometimes more than once). I'm sure this is due to the fact that the print head is on the cartridge & becomes worn with repeated use. I print many photos & use refilled cartridges for this purpose & get beautiful results.
