Apparently this high end printer is wasting some very valuable ink! THE SHAME!
The high-end Epson 9900 printer, which retails for around £3,000 ($5,000), reports that ink cartridges are empty even when they are still about 15-20 percent full. This behaviour is particularly egregious as a set of 700ml ink cartridges for the Epson 9900 printer comes in at around £2,500—so, users are being forced to replace the cartridges when there’s still about £500 of ink available.
This finding comes from Bellevue Fine Art, a printing company in Seattle. When their Epson 9900 printer reported that an ink cartridge was down below 1 percent capacity, it refused to print any more pages until the cartridge had been replaced. Bellevue Fine Art, in a fit of curiosity, decided to cut open some of the allegedly empty cartridges to see how much ink was actually left.
You will probably be unsurprised to hear that there was actually a lot of ink still available: in a 700ml cartridge, there was generally between 100 and 150 millilitres of ink still in the bag, about 14-21 percent. In smaller, 350ml cartridges, between 60 and 80ml of ink remained or about 17-22 percent.
