[High] Check Method
<WARNING>
Check visually that the
rotation of the DEVE.
FAN goes to high
speed.
(During executing with
code [61], executing
this code changes the
DEVE. FAN to high
speed.)
<WARNING>
Check visually the
rotation of the DEVE.
FAN.
<WARNING>
<CAUTION>
Check by the change
in operational sound or
visually that the
rotation of two motors
goes to low speed (1/3
speed).
(During executing with
code [53] and [57],
executing this code
changes the FUSER
MOTOR ASSY and
the P/H MOTOR
ASSY to 1/3 speed.)
<WARNING>
Check visually the
rotation (low speed) of
the FUSER FAN-1.
