L3-00 indicates scan carriage motor trouble. The carriage with all the mirors on it is not moving at all (scanning) or is not moving at the required speed so it does not reach its "home" position. If restarting the copier does resolve the issue....
A few things to check... When you turn copier on does carriage move at all? if not then the motor could be bound up (not turning) - also make sure the cables pulling the carriage are properly wound. remove the main glass and make sure there are no obstructions in the way of the carriage (a loose cable maybe or dirt) can you move the cable by hand freely? if the motor locks up it could be really hard to move the carriage.
The carriage seems to be moving freely (by hand and when you turn the copier on) it could possibly be the "home position" sensor that is faulty and not reading the correct position of the carriage.
You can the copier in test mode to check either the motor or sensor. press the following keys one after the other # * C * then press start/enter , press 1 and start/enter again, sub code 1 will test the motor and sub code 2 will test the sensor.
So it could be a bad motor or sensor or the MCU board that drives the motor (or may just need a good cleaning).
