What to do if my Canon PIXMA MP140 shows error E4?

If your Canon All in One Printer displays error E, 4, it means the ink has run out. To resolve this, replace the ink cartridge and close the Scanning Unit (Printer Cover). If printing is in progress and you wish to continue, press the Stop/Reset button for at least 5 seconds with the ink cartridge installed.
