http://arstechnica.com/news.ars/post/20070618-study-inkjet-printers-are-filthy-lying-thieves.htmlA new study says that on average, more than half of the ink from inkjet cartridges is wasted when users toss them in the garbage. Why is that interesting? According to the study, users are tossing the cartridges when their printers are telling them they're out of ink, not when they necessarily are out of ink.
The study by TÜV Rheinland looked at inkjet efficiency across multiple brands, including Epson (who commissioned the study), Lexmark, Canon, HP, Kodak, and Brother. They studied the efficiency of both single and multi-ink cartridges. Espon's printers were among the highest rated, at more than 80 percent efficiency using single-ink cartridges. Kodak's EasyShare 5300 was panned as the worst printer tested, wasting 64 percent of its ink in tests. TÜV Rheinland measured cartridge weights before and after use, stopping use when printers reported that they were out of ink.
That's the first problem. Printers routinely report that they are low on ink even when they aren't, and in some cases there are still hundreds of pages worth of ink left......
