Function
Performs the TD sensor initial setting.
This SP mode controls the voltage
applied to the TD sensor to make the TD
sensor output about 2.0 V.
After installing a new PCU, the machine
performs this function automatically.
Do not use this SP mode.
Adjusts the discharge brush voltage at the
leading edge on the front side.
Increase if the paper is getting wrapped
around the drum.
Adjusts the discharge brush voltage on
the front side except at the leading edge.
Adjusts the discharge brush voltage at the
leading edge on the rear side.
For the rear side in duplex mode, higher
voltage is needed. The paper has more
static on it, and there is toner on one side
of the paper.
Adjusts the discharge voltage on the rear
side except at the leading edge.
Selects whether the FCI smoothing
function to remove jagged edges is
enabled or disabled (this adjustment does
not affect fax mode)
Selects the laser pulse positioning type
that is used for independent black or gray
