I noticed that too - although I think it's only happened once with me.

Ian,

Respectfully, there are some very good remanufacturers. I have conducted testing, in my consulting capasity, for some of the large chain retail stores. We evaluated image quality (both photo and general), printer issues ( starts, non head clogging, leaking, and many others), costs, and storage life. These high quality houses measure printed dot size ( and in no case is it as fine as the OEM due to nozzle wear, resistor damage, and patent required in ink formulations) and use quality inks to approach OEM performance. I have tested OEM cartridges and refilled them with OEM ink and compaired the images to this premium after market ink and they past muster. But I would never say a remanufactured cartridge image quality equals and first time printed OEM. As I stated in a previous post in this discussion there are some very good remanufactured cartridges and a lot of junk. The reliability numbers I quoted were from years of running a plant that made OEM cartridges and after market cartridges. These numbers are based on millions of cartridges and not a casual sampling, as some printed media do ( note large amounts of advertising money).

The compatible cartridge is a different story. We manufactured food grade compatibles inkjet and dye sublimation cartridges in a class 100 clean room clean room approved by the goverent "food and drug administration".
The pigmented inks we formulated ( without violating their patents) matched the Epson inks within 1 delta E on the OEM paper. The accelerated aging ( yardstick test not valid unless verified by long term in parallel ) approached that OEM.
Bottom line is that with a high quality compatible cartridge photo print quality approaches the OEM.
We are unable to do the same with a remaufactured, printhead/ink tank, to approach OEM phot image print quality. But for general use and casual photo shots it gets pretty good.
