UNDERSTANDING THE STATUS LED
The color of the Status LED indicates the machine's current status.
ACKNOWLEDGING THE STATUS OF THE
TONER CARTRIDGE
The status of toner cartridges is indicated by the Status LED and the LCD
display. If the toner cartridge is low or needs to be replaced, the Status LED
turns red and the display shows the message. However the arrow mark
shows which color toner is of concern or may be installed with a new
cartridge.
Example:
The above example shows the yellow cartridge status indicated by the
arrow. Check the message to find out what the problem is and how to solve
it. See "Understanding display messages" on page 57 to browse the
