There are a couple of different ways to measure these volumes. The WeInk "UltraFill" method actaully gives you a preview of the fill volume, and seems to be accurate to 1-2 cc. By that measure, I got about 13 cc for the color chambers on a 1520/1160 cart, and about 23 cc for the black cart (1520/1160) on the initial fill of a new set of cartridges. The other method is with a disassembled cart, with the sponge removed. In this case, I measured about 15 cc for the color chambers. (I haven't done this for the black cart.) It looks like the sponge itself displaces 2-3 cc. Refill volumes are substantially lower -- around 60-70% of the maximum or theoretical volume. This simply proves (??) that 30-40% of the ink is stuck forever in the sponge, and will never make it to the print head. rafe b. - Please turn off HTML mail features. Keep quoted material short.
