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