Adjusts the laser power by changing the current applied to LD.
Laser power is automatically adjusted during process control; therefore, adjusting these
data has no effect while Process Control (SP3-125 Default : ON) is activated.
After deactivating Process Control with SP3-125, the values in these SP modes are used
for printing.

Function / [ Setting ]
* Sets the upper limit of the AC component
adjustable range for color.
During machine initialization and process control
self-check, the AC component of the charge roller
bias is automatically adjusted within the range
specified in the SP2-001-021 and 022.

* Displays the result of the latest line position
adjustment. Changing this affects the main scan
*
magnification; however, this will be automatically
*
corrected at the next line position adjustment. If a
*
fine adjustment is required, it can be done with
*
SP5-993-013 to 015 (this affects the way that the
adjustment is done, and will be effective from the
next line position adjustment).
[ 0 to 280 / 140 / 1 dot/step ] 1 dot = 20µ DFU
NOTE: If the line position adjustment does not
work properly, the line position can be
adjusted manually with this SP mode as a
temporary measure. In this case, the line
position adjustment needs to be disabled
with SP5-993-001.
