ENGINE SERVICE MODE
G130/G131 5-20 SM
[LD Control] LD Power Control
([Color Mode, Color], Process Speed, K or Color mode) P: Power, M: Magnification
2103
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.

2103 014 P:[K] M K *BCU [0 to 1023 / 683 / 1/step] DFU
2103 015 P:[K] H K *BCU [0 to 1023 / 683 / 1/step] DFU
Main Scan Magnification ([Color], Laser Exposure Frequency)
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 560 / 280 / 1/2 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.
