Orange light on laser jet proM203dw

[JKW73]

What does steady (not blinking) orange light on top panel mean? Ink seems fine on print jobs but it just came on last week and  now doesn’t disappear.

Now that I know the orange light means my toner is low, even though the print doesn't appear to be fading, how do i order new toner for the laser jetpro M203dw?

You can buy toners online, the indicator only informs the user that the toner is low so that a user can prepare a new toner for replacement. When print gets faded then you replace the toner, not sooner.
