Use SIM 03-11 to check the shifter motor operations. Check connection of the harness/connector of the shifter motor. Replace the shifter motor. Replace the MCU PWB.

The L6 code means trouble with the laser unit ( polygon motor), it has to be replaced. The laser unit is under the exit tray. Hope this helps.
SOURCE: Sharp AR-M207 Error Message
H4-00 means heat roller low temperature detection. It usuallly caused by 3 things :
1. The machine hang : You simply reset the error code by pressing : # * C * then input 14 then start.
2. If the error still displayed, open the side cover, feel the fusing unit ( don't touch, it is hot ), if the
fusing unit feels cold then the problem is the heater lamp ( inside the upper heater roller,
connected with anti heat cable and big connector ), you should replace it.
3. If the fusing unit feels warm or hot then the problem is the thermistor ( connected with small cable
and connector ), replace it.
