What does an orange light indicate on my printer?

A flashing orange light on a printer can mean a few things but it usually means a problem of some kind.

Flashing orange light

Open the printer's cover and make sure the paper is not jammed.
Close the printer's cover.
Turn the printer off, then back on.

Solid orange light

Open the printer's cover.
Remove the roll and reload it so it feeds up from the bottom of the roll. If there is no paper left, load a new roll.
Close the cover on the paper.
If the light does not turn off, power the printer off and on and wait for a solid blue status light.
