Function
Displays the real time toner sensor output
voltage.
In this mode, the PTL, main motor, QL and
the bias voltage for non-image areas can be
turned on and off using the Copy Media key.
Translucent paper = ON
Translucent Film = OFF
Even if the SP mode is canceled when the
voltage is displayed, the voltage is displayed
during the stand-by condition or copy cycling
(the toner sensor output voltage, paper
length and copy counter are displayed one
after the other).
To release this condition, turn the main
switch off and on.
Goes to "Ready" condition ignoring the fusing
temperature. This mode cannot be used
during the development idling.
Fluorescent lamp does not turn on during the
copy cycle.
Ignores jam detections except for initial
jams. The setting automatically returns to "0"
when the main switch is turned off.
The machine caries out copy operation
without an original. This mode can be used if
the optional roll feeder is installed and
selected paper length is more than 594mm.
The machine starts operation when the roll
feed select key is pressed, and stops when
the Emergency Stop key is pressed.
Counts the time when the exposure sensor is
more than 1 V higher than the target value.
