What does it mean if my Canon PIXMA MP140 All in One Printer displays errors E2x E3x E4x?

If your Canon All in One Printer displays errors such as E, 2, x E, 3, x E, 4, x, it indicates that an error requiring servicing might have occurred. Turn off the machine and unplug the power cord from the power supply.
