      Maybe not a conspiracy.  I read on some forum recently, I read so many, that all inks are not created equally, and do not work as well as OEM inks in Epson printers.  It has to do with how the inks come out of the nozzles and deflections in the spray pattern.  The person who wrote the posting said it had to do with testing the heads during the manufacturing process, and assigning codes to them, and applying that code to the firmware that runs the printer.  This code makes the printer work properly with that head, with the OEM inks only which have a known quality.  If the consistency of the ink is changed, the head can have deflections which can cause banding.  



This posting may have been on the Epson WF group.



The posting went on to say that the nozzle check with 3rd. party inks will print fine, yet banding will show up in prints.  Also stated that no amount of head cleanings will clear this banding.



I found it to be true with my Epson 9500.  Prints great with OEM inks, but when I tried the MIS ink, I had micro-banding, and strange patterns in the dark smooth toned areas of my prints.  Go back to the OEM and everything is fine again.  NUTZ!  I wish it weren't so, but it sure seems to be.



As a last note, this posting went on to say that this was the reason 

Epson wants to keep control of their printer head sales.  They did not want to release the information on how to correct for this code on their printers and give other manufactures their secrets.
