Checks for bad sectors on the hard disk
that develop during machine use. Press
"1" to start. This takes 4 minutes.
This SP mode should be done when an
abnormal image is printed. There is no
need to do this at installation as the
hard disk firmware already contains bad
sector information, and damage is not
likely to occur during transportation.
Bad sectors detected with this SP mode
will be stored in the NVRAM with the
bad sector data copied across from the
firmware.
If the machine detects over 50 bad
sectors, SC361 will be generated. At
this time, use SP4-911-2.
Formats the hard disk. This takes 4
