3-2. Hardware – Printer
Main board
(MAIN_BD) adopts 30V from power board to control the motor driver ICs that
drives the motors and the mechanisms. The main board also converts input from 30V to 5V and
3.3V by voltage regulators of ASIC to Memory, Video IC, and the I/Os.
Notes: There is no hardware adjustment required for the main board of printer; the ribbon sensors can be
adjusted through special software device.
1. OEE ASIC – Print Engine
We call this the print engine because it’s in charge of the motor and USB connection, all the printer
operations.
1-1.
SDRAM for Print Engine. This
32MB
SDRAM is to be used as storing data buffer. The image
file, print data, video frame are temporarily stored during operation.
1-2. (On the back side) NOR Flash for Print Engine.
This 1MB flash memory stores the MCU code.
2. FPGA – ALTERA
This chip controls the TPH interface, Capstan motor, cutter door motor, and I/O.
3.
USB2.0
This is the USB 2.0 IC chip.
