This is a fuser related error - the fuser is not warming up within a specified time frame. It could be the heater lamp or a thermostat/thermistor that is not working, possibly a bad fan. You can cancel the error code (hopefully the error does not come back) by going into sim mode. press the following keys one after the other "clear" "density select key" "clear" "density select key" then enter 14 and the copy start key. then restart the copier. If error code persists you could remove the fuser unit and look for any foreign matter inside the fuser. dirty thermistor or thermostat can cause this too.
Hope this helps

The white area and the black marking on the shading plate are used to obtain the difference in the CCD level values for judgment of lock. When the difference in the levels of which and black is small, it is judged that the black mark could not be scanned by lock and the trouble code “L1” is displayed.
