LED Patterns and Indications

The LEDs on your machine's control panel light up, dim, or blink to indicate machine status.

This table defines what LEDs indicate when they light up, dim, or blink.

LED indication	Status	Meaning
	Sleep	In Sleep mode (Power Save mode), the machine acts as if it is turned off, but it can still receive data. Receiving a print job will wake the machine and it will start printing.

	Printing	The machine is printing.
	Cooling Down	The machine is cooling down. Wait for 10 minutes or until the inside of the machine has cooled down.

As with any sophisticated office product, errors may occur and supply items may have to be replaced. If this happens, your machine identifies the error or required routine maintenance and the Status Monitor indicates the appropriate message. The most common error and maintenance indications are shown in the table.

Follow the instructions in the Actions to improve the status.
