I was sent the following after an inquiry. Hopefully this provides a little additional info:

==================

SC990 is a level 'b' service code which basically means powering off / on is sufficient to reset this error.

If it's constantly re-occuring after a hard boot then there is clearly a bigger problem that needs correcting.
SC990 is not clear cut as it can and does occur for many different reasons.
Bad drum grounding, HDD fault, loose/snagged harness, blown internal fuses, corupt NVRAM, corupt firmware, bad memory, blown BICU, controller, PSU etc.

H5-01 indicates tha the paper sensor is defective in the fusing unit. The only way you can try to reset that one is buy turning the power off, wait 30 seconds and turn the power back on.

If the error code returns the fusing unit will have to be fixed to take care of the paper sensor.
