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, no paper, the open top or
front cover, or the empty toner cartridge.
See “Troubleshooting Error Messages” on page 5.16.
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 On
Line/Error LED blinks green.
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.
