LED	Description

If the On Line/Error lights green, the printer is ready to print.

If the On Line/Error lights red, the printer is experiencing an error,

such as jammed paper, no paper, the open cover or the empty toner cartridge.

If you press the Cancel button while the printer is receiving data, the On Line/Error LED blinks red to cancel printing.

In Manual Feed mode, if there is no paper in the tray, the OnLine/Error LED blinks red.

Load paper into the tray and the LED stops blinking.

If the printer is receiving data, the On Line/Error LED slowly blinks green.

If the printer is printing the received data, the On Line/Error LED blinks green fast.

If you press the Cancel button in Ready mode, this LED is on and the Toner Save mode is enabled.

If you press this button once again, this LED is off and the Toner Save mode is disabled.

If the On Line/Error and Toner Save LEDs blink, your system has some problems.
