Artemis writes: Epson has released a report they commissioned on "empty" inkjet cartridges. The interesting part? The cartridge and the printer disagree on when it is actually out of ink! The study looked into the efficiency of both single and multi-ink cartridges. The cartridges were measured before and after use and were considered empty when the printed reported they were empty. The Kodak EasyShare 5300 ranked worst in the study, indicating it was out of ink where it was still actually 64% full! These results are horrible, but even the best inkjet printers left an average of 20% of the ink in their cartridges when they were reported empty.
