C400 is exposure lamp fails to come on, on start up the main exposure lamp should come on and do a scan.
If the lamp is not detected by the sensor, then you get the code.
Restart the machine, watch for the exposure lamp. if it does not come on before the code occurs, then the lamp or thermal fuse is likely gone.
if the lamp comes on then the code, the AE sensor is likely gone.

Hope this is of some help.

The C0400 deals with the scanning lamp not turning ON. I would check the fuse for the scanning lamp and check the lamp to see if it is blown. You will most likely need to replace one or both of the parts. Good Luck
