Function
Displays the development bias.
SP2-206-001: Development bias used
for copying.
SP2-206-002: Development bias used
for making V
patterns.
The first two digits are displayed in the
reduce/enlarge indicator. The actual value is:
displayed value x (–10) V. All process control
corrections are included in the displayed value.
Forces the toner bottle to supply toner to the
toner supply unit for 30 seconds.
This mode is started by pressing the "Start"
key and stops automatically after about 30
seconds. Press the"Clear Modes" key to
interrupt if necessary. This SP mode must be
performed twice when installing the machine
and when installing a new toner supply unit.
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.
