When [OK]/[START] key is pressed, the scanner mode counter value is cleared to 0, and
"000,000" is displayed on the LCD/display.

24-15 S-MODE CLR.
CLEARED
[Function]
When [OK]/[START] key is pressed, the main motor (and the duplex motor in the case of a
duplex model) is operated for 30sec.
To reduce toner consumption, if the developing unit is installed, the developing bias, the main
charger, and the grid are also outputted.
In this case, laser discharge is required when stopping the motor, the polygon motor is also
operated at the same time. Check for installation of the developing unit. If it is not installed, the
high voltage above is not outputted and only the motor is rotated.
To check the developing bias, install the developing unit.
After completion of 30sec operation, the machine goes into the sub code entry standby mode.

[Function]
When [OK]/[START] key is pressed, the Bios is called to rotate the polygon motor for 30sec.
After completion of 30sec operation, the operation is turned off with the Bios and the machine
goes into the sub code entry standby mode.
