The printing operation is carried out in normal mode. Under ordinary circumstances such as when the
power is turned on or when LOADI, signal level is low, the normal mode is enabled.
The printing operation is carried out in the following sequence. First, the printing data DATAI3 through
DATAI0 are stored, sequentially shifted, in the shift registers of the LED drivers, by the printing data
synchronous clock, CLOCKI. Then the printing data stored in shift registers are latched by the high level
pulse of LOADI. The latched printing data turns the LEDs on by STRB1I-N through STRB4I-N and
actuates printing.
The mode setting timing chart during illumination correction is shown below.
The mode setting is carried out in the following manner. LOADI is fixed at high level, and DATAI0 which
comes up following this is 4-data latched with the timing of the fall of CLOCKI. The illumination correction
mode is selected based on the latched 4-data combination. Then the mode becomes valid at the fifth fall
of CLOCKI.
