Got a service manual and looked up the parts ;)

Hold down the Copy button and you should see a readout for the total copies printed from the copier and the percentage of toner left in the unit.

Your main heater lamp has gone bad.

L1-00 is determined as "scanner feed trouble". The scanner unit (which holds the mirrors) is not moving as it should be. There are a few possibilities. Firstly, does the mirror unit move when the copier is turned on? if not it could be a disconnected/broken scanner wire or bad drive motor or simply dirt/debris or a loose wire binding the unit up.
If the unit moves on power up then it could be a bad sensor or a bad board not registering the signal from the sensor.
You can check the operation of these items in SIM mode : press the following keys one after the other "P" "*" "C" "*" then press 1 and enter/copy button and you'll see the option available.
I hope that helps.
