(10) Sleep Mode Indication (OFF/Dimmed)
This is to select whether the Status LED is turned off completely or lit in green with low
light intensity during the Sleep mode. Whenever you switch this mode, the setting is
changed over from the present one to the other. When you take your finger off from this
switch, the Status LED is lit in 100% light intensity or low light intensity according to the
setting so that you can verify the present setting.
(11) Sleep Mode Setting (ON/OFF)
This is to allow you to turn on and off the sleep mode of the printer. The default setting is
ON. The machine automatically goes back to the ready state after the operation is
completed.
(12) Developer Roller Counter Reset 1 (For the standard toner)
(13) Developer Roller Counter Reset 2 (For the high yield toner)
Since print density is likely to become darker as toner is getting older, the developing bias
is lowered by degrees according to the number of prints so that an almost fixed density
can be maintained from the start of the use of brand-new toner to the end of it. The value
of the developing bias is printed on the maintenance sheet. The developing bias is a
parameter which depends on the developing assembly, so it needs to be reset when the
developing assembly is replaced. At that time, the developing roller counter reading is
also reset. This mode is to enable to execute these operations (equivalent to those done
when the developing assembly is replaced) manually from the service mode.
(14) Fixed USB Speed
This allows you to switch the setting of Full fixed / Auto switching (HIGH/FULL) of the
USB speed. Whenever switching, the current setting is changed to the other one.
The default setting is Auto switching.
It also allows you to check the selected setting by the Toner or Drum LED being lit for
1 second when releasing the button. The former shows that the setting is Full fixed, and
the latter shows Auto switching.
(15) USB Speed Indication (ON/OFF)
This allows you to switch whether the current USB speed is indicated with the LED or not.
Whenever switching, the current setting is changed to the other one.
The USB speed is not indicated by default.
It also allows you to check the selected setting by the Toner and Drum LEDs being lit
for 1 second or all LEDs being lit for 1 second when releasing the button. The former
shows that the USB speed indication is ON, and the latter shows OFF.
