Sets the grid voltage correction data to correct
the output from the high voltage supply board.
(A label on the high voltage supply board gives
the correct value.
When the high voltage supply board [CTBG] is
replaced, set the data using SP62 before
performing SP57.)
Agitates new black developer for about 5
minutes.
Press the start key to begin operation.
(This mode must be done when new black
developer is put in.
Beeper sounds 5 times when the initialization
is completed.)
Used to set new drum condition.
(This must be done when a new drum is
installed. The OPC counter, V
level, and Vref [initial Vlp/Vlg] are cleared.
To set, press "1" then the "#" key.
Beeper sounds 5 times when the initialization
is done.)
Displays the present V
(V
level [%]=Vrp/Vrg x 100)
R
Displays the present Vdat. [Vlp/Vlg x
100=Vdat]
The V
level (%) is displayed while the "• " key
L
is held down.
(V
level [%]=Vdat/Vref x 100= [(Vlp/Vlg)/
L
(Initial Vlp/Vlg)] x 100.)
Detects V
correction level regardless of the
R
drum counter.
(The detection will be done in the first 5 copy
cycles after exiting the SP mode.
R
Beeper sounds 5 times when this mode is
accepted.)
Detects V
correction level regardless of the
L
drum counter.
(V
pattern detection is done 4 times.
L
Beeper sounds for each detection and Vdat is
L
displayed in the three digit indicator each time.
The average of the 4 detections can be
monitored by SP68.)
