An LED correcting head, which is capable of correcting the illumination of the LED for each dot, is being used in this printer. LED illumination correction function

of 16 steps is carried out by using an EEPROM which is installed in the LSI that maintains the LED illumination correction values, and an LED correction drivers

together as a pair.

The printing and correction data obtained from the CPU through four signal lines are sent to the LED array.

The printing operation timing chart is shown below.
