Main Scan Adjustment: LED Light Level at LPH Joints
After you do the previous procedure to adjust the main scan at the LPH joints, you can do a fine adjustment
on this area. To do this, you increase or decrease the intensity of the light from the four LEDs at the joints.
"500" is the default setting for LPH 1-2 and LPH 2-3.
• If you change the 2nd digit of the value for LPH 1-2 (500 to 510) with SP2952-1, this moves the four
LEDs by one position to the left.
• If you change the 2nd digit of the value for LPH 2-3 (500 to 510) with SP2952-2, this moves the four
LEDs by one position to the right.
• If you change the 3rd digit of LPH 1-2 or LPH 2-3 (510 to 512, for example), this increases the
quantity of light from LEDs 1, 2, 3, 4 in the illustration.
The quantity of light can be adjusted for each LED independently with SP2953 (Power Correction). But,
this fine adjustment is usually not necessary in the field.
