On Line/Error and Toner Save LEDs
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, the open cover or the empty
toner cartridge. See “Troubleshooting Error Messages” on
page 6.18.
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 Manual
Feeder, the On Line/Error LED blinks red. Load paper into
the Manual Feeder 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.
