Hi David,

It is still not recommeded to mix the inks, however there are other factors in play in this case. Since it is a 1280, you would need a new bulk system, and all new inks. The 1280 has been discontinued, and they are no longer available from Epson new. I would be leary to invest the money for a bulk system and new inks, when if something happens to the printer several months down the road, you may not be able to get a replacement. I would look seriously at an upgrade printer at this point. You would also get into a printer that functions much better than the 1280.
