Shaking the Printer Cartridges
Raise the Epson printer cover while the power is turned on, then wait for the carriage to stop sliding back and forth. Remove all printing cartridges by squeezing the tabs on the short ends of each cartridge and lifting straight out. Turn off the printer and wait for it to shut down completely. Unplug the printer from the power source and wait at least five minutes for the printer memory to reset. Shake each cartridge a few seconds to redistribute the ink inside. Reinstall the cartridges in the same order as each was removed and then restore power to the printer.
Resetting the Printer Cartridges
After removing the printer cartridges, examine the end of a cartridge where the copper contacts are found. On some models, there is a reset button located above the contacts in the center. Press the reset button using the end of a paperclip or other sharp object of a similar size. After resetting each cartridge, you can then replace them and the printer should accept them as if they were new. Tips Writer Bio
