First line printing

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.
