Ink cartridges. The Imaging Supplies Coalition, which includes Brother, Canon, Epson, Lexmark, Oki, Toshiba, and Xerox, created a program it calls WIDCIO: When In Doubt Check It Out. Send your questionable cartridges to the ISC, and the organization will send them to its member companies to determine whether they're counterfeit, infringe on a patent, have been used, or were remanufactured and sold as new. Then the ISC asks you to name the seller (confidentially) so the company can give chase. Twenty percent of the cartridges the ISC receives turn out to be fakes of some kind, which means most bad cartridges should be covered by warranty. For more info, call the ISC at 941-961-7897 or go to its website at www.isc-inc.org.
