The settings 0 and 1 are the same as
for 4909-17 above. The setting 2
means that the black level of the
stamp (SP4904-17) is inverted (e.g.
when the black level of the stamp is
200, the stamp pattern is printed at
black level 55.)
This SP mode is used when a stamp
pattern is overlapping a solid black
area.
These SP modes are used for

Checks for bad sectors on the hard
disk that develop during machine
use. 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 during
transportation.
Bad sectors detected with this SP
mode will be stored in the E
on the EX-IPU board with the bad
sector data copied across from the
firmware.
Formats the hard disk. This takes 8
minutes.
Do not turn off the main switch
during this process.
