Function and [Setting]
Displays how many times the LD unit position has
been changed (how many times the resolution has
changed.)
When the laser beam pitch adjustment is done, this
counter is reset to zero.
Resets the values of SP2-109-6 and SP2-109-7.
After replacing the LD unit, this SP mode must be
performed. See the LD Unit Removal Procedure.
Sets the scanning resolution (dpi). DFU

Input the time that the polygon motor is to switch off
after the printer has remained idle for the specified
time and entered the standby mode.
If set to zero, the polygon motor never switches off
in standby mode. However, if the machine enters
the energy saver mode, the polygon motor will
ignore the zero setting and switch itself off.

Adjusts the development bias for copying.
Use as a temporary measure to correct faint copies
from an aging drum.

Forces the toner bottle to supply toner at 1-second
intervals for up to 30 seconds. To start, press .
Selects the toner mode.
0: Sensor control
1: Image pixel count.
If you select 1, SP2-209-002 should be set to its
default value. Use image pixel count modes only as
a temporary measure if the ID or TD sensor is
defective.
Adjusts the toner supply rate.
Sets the amount of toner supplied every second by
the toner supply motor.
Increasing this value reduces the toner supply
clutch on time. Use a lower value if the user tends
to make lots of copies that have a high proportion of
black.
