It's been a while since you posted that but you may just need to slide it back out and shake it back and forth (long ways) a few times. We had the same problem and the konica minolta tech told us to do that. It worked. DO NOT turn it upside down though.

SOURCE: Clearing a service code ''C0400'' on a Minolta CS Pro 6001

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.
