The period during which the illumination correction mode is valid is from the fall of the fifth CLOCKI and
while the level of LOADI is high. When the level of LOADI becomes low, the illumination correction mode
is terminated, and the head returns to the normal mode, which is mode with which the printing is normally
carried out.
The LED driver (MSM6731BWAF) corrects the LED illumination by controlling the LED current. The LED
illumination can be set in 16 steps, with 7 steps in the direction of illumination increase in relation to the
standard value, and 8 steps in the direction of decrease. For this reason, the LED correction data is a 4-bit
data for each dot.
The relationship between the LED correction data and LED current correction steps with the LED driver
(MSM6731BWAF) used in an LED head is shown below.
