IMO, this reasoning is not correct. Epson themselves have all the resources in the world to fill ink carts properly. I wouldn't be surprised if the machine/apparatus that does this costs hundreds of thousands of dollars. My guess is that they use a bell-jar. The entire (empty) cart is placed in a roughing vacuum, so that the ink, when introduced into the cart, fills it as completely as possible. This would also need some apparatus inside the bell jar to open/ close various vents and fill ports in the proper sequence. The bell jar is probably large enough to hold many cartridges at once. Just a guess!!! I once had a look at the ink carts in a small Canon desktop inkjet printer. They seemed eminently reasonable in their design. There were two compartments for each color. One compartment held sponge, and the other held liquid ink. The carts were all clearly visible, so that you could judge by eye exactly how full each color was. I have been agonzing over "refill economics" for several days now. You've given me an interesting idea. Forget about Epson. Go with a brand that uses a more user- friendly ink-delivery system. Or screw these small Epsons, bite the bullet, and get a 3000. rafe b. - Please turn off HTML mail features. Keep quoted material short.
