The printing operation timing chart is shown below.
Normal Mode Printing Timing Chart
The printing operation is carried out in normal mode. Under ordinary circumstances such as when the
power is turned on or when LOAD signal level is low, the normal mode is enabled.
The printing operation is carried out in the following sequence. First, the printing data DATA3 through
DATA0 are stored, sequentially shifted, in the shift registers of the LED drivers, by the printing data
synchronous clock, CLOCK. Then the printing data stored in shift registers are latched by the high level
pulse of LOAD. The latched printing data turns the LEDs on by STRB1-N through STRB4-N and actuates
printing.
