Control-panel display problems


Static electricity can cause unexpected black lines or dots to appear on the all-in-

one control-panel display. Do not touch the all-in-one control-panel display if there is a chance
that you have collected a static electric charge (for example, by walking on carpet in a low-
humidity environment).

Unexpected lines or dots might appear on the all-in-one control-panel display, or the display might
become blank if the all-in-one is exposed to an electric or magnetic field. To resolve this problem,
perform the following procedure:


Turn the all-in-one off.


Remove the all-in-one from the electric or magnetic field.


Turn the all-in-one on again.
