R51 Circuit Diagram (Page 6/12)
1.
Block diagram
The circuit diagram shown on page 6/12 consists of connector CN12 that provides an
interface between R51 board and LED print head.
Figure A3.1.6 shows the related signals and block diagram of LED print head.
2.
Function
Data of 1664 LEDs on the LED print head is loaded into the shift registers by the HCLCK
(4MHz or 6.7 MHz) signal. After the 1664 bit (208 mm) data is loaded in the shift regis-
ters, it is then loaded in the latch circuit by the HLATCH signal. The turning -on and off of
the LEDs are controlled by STRB1-N to STRB4-N signals.
