If your printer’s ink cartridge runs dry near the end of an important print job, remove the cartridge and run a hair dryer on it for two to three minutes. Then place the cartridge back into the printer and try again while it is still warm.
“The heat from the hair dryer heats the thick ink, and helps it to flow through the tiny nozzles in the cartridge,” says Alex Cox, a software engineer in Seattle. “When the cartridge is almost dead, those nozzles are often nearly clogged with dried ink, so helping the ink to flow will let more ink out of the nozzles.” The hair dryer trick can squeeze a few more pages out of a cartridge after the printer declares it is empty.
I like the one about turning your head into an antenna, too.
