Function
Selects the toner supply mode.
In many cases, the machine will change
the toner supply mode automatically if
either the TD or ID sensor become
unreliable. However, sometimes it does
not.
If the TD sensor fails, you can select
fixed supply mode as a temporary
measure.
If the ID sensor fails, you can select TD
sensor supply mode.
After repairing the machine, check
whether the toner supply mode has gone
back to the detect supply mode.
Selects the toner supply ratio for TD
sensor supply mode.
For example, if the user normally makes
copies of originals that are about 7%
black, select the 7% setting for best
results.
Selects the toner supply ratio for Fixed
Supply Mode.
For example, if the user normally makes
copies of originals that are about 6%
black, select the 6% setting for best
results.
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
key and stops automatically after about
2.5 minutes. Use this mode only after
adding new developer.
