Hi. The SC220 issue is a known one on the 3800c. It's a firmware related problem, and the code, which points to the synchronizing detector boards, is erroneous. You can read more about it, and possible ways to avoid it here.
Updating the firmware to get rid of this problem is not an easy job.

sc220 is a laser sync error. You'll probably need to either replace the laser sync board or the laser diode itself, so you may want to contact a local service technician, as both of these components are internal and can be slightly tricky to get to.
