Function
Performs the TD sensor initial setting. This SP
mode controls the voltage applied to the TD
sensor to make the TD sensor output 2.5 ± 0.1
V.
After using SP2-214, check SP2-220 to see if
the sensor is working correctly.
This mode is started by pressing the Start key
and stops automatically after about 2.5
minutes. Use this mode only after adding new
developer.

sensor output
Displays the TD sensor initial setting output
(after doing SP2-214).
Normally, 2.5 ± 0.1 V is displayed.
[Range: 0 V to 5.0 V]
If it is not, the sensor may be defective.
Selects the toner supply ratio for detect supply
mode.
For example, if the user normally makes
copies of originals that are about 7% black,
select the 7% setting for best results.
After the Start key is pressed, the developer is
agitated. To stop, press the "Clear Stop" key.
Use this SP mode if the machine has not been
used for a long time.
