E17 Circuit Diagram
1.
Block diagram
The circuit diagram shown on page 9/16 consists of connector CN2 that provides an interface
between E17 board and LED print head.
Figure A3.1.10 shows the related signals and block diagram of LED print head.

Function
Data of 1664 LEDs on the LED print head is loaded into the shift registers by the HCLCK (6.67
MHz) signal. After the 1664 bit (208mm) data is loaded in the shift registers, 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.
LED head interface signals output from CPU
• HDATA 0
: Print data i.e., data to be printed
• HCLCK
: Transfer clock for print data (6.67 MHz)
• HLATCH
: Latch signal for print data
• STRB1-N to STRB4-N : LED head strobe signals
