Chapter 3. Hardware
630PS Circuit Theory
The circuit of 630PS contains five parts: main board, power board, card board,
controller board, wires & cables. Functionally, power board is an AC to DC
power conversion device, and it provides a 75W, 18V, DC source to drive the
630PS photo printer. Main board adopts 18VDC from power board to drive
motor driver ICs and fan, and also transforms the input 18V to 5V and 3.3V by
voltage regulators for ASIC, Memory, Video IC, and the I/Os. Card board,
which adopts 3.3V DC from main board, provides an interface for main board
to control CompactFlash and SmartMedia memory card, it is connected with
main board by a 3 pins power wire and a 50 pins signal cable. Controller board,
which consists of a 1.6-inch TFT-LCD panel, the user buttons, and the control
circuit, is to be the user interface (UI). The 18V DC from power board and the
video signals from main board are connected to controller board. Besides, The
TFT-LCD panel on controller board is to display images and messages for user
operations.

3.1.1 ASIC Architecture
The most important IC on the main board is FD2680E, which is designed by
HITI. This ASIC contains a DSP core, a 8032 MCU, a SDRAM controller, a
CCIR601/656 Video controller, a CompactFlash card controller, a SmartMedia
card controller, a multi-type thermal print engine, an USB controller, the
embedded SRAM, an ADC, and IOs. Firmware can control the action of printer
via the versatile interfaces of FD2680E ASIC.

3.1.5 LED & Sensor
3.1.5.1 Status/Error LED
Show printer status and error message. Green shining LED means printer is
ready. Green blinking LED means printer is busy. Orange blinking LED means
error message. (See “Chapter 7. Troubleshooting” for more information about
error message.)
Fig 6. Status/Error Sensor
3.1.5.2 CAM Sensor
Under different status, the position of platen roller is different. Cam sensor
indicates the position of platen roller and pinch roller. It has three positions, P1:
initial position, P2: load position, and P3: print position. The CAM controls the
platen roller moving between these positions, and the CAM sensor detects &
feedback the position information to firmware.
P1 = Initial Position
At this position, the gap between platen roller & TPH is largest. While
printer power on or reset, it will be at this position. The large gap
between platen roller & TPH enable paper moving through the gap.
At this position, the pinch roller is releasing as well.

Ver. Ex.1.1 Confidential 2003/7/8
P2 = Load Position
At this position, the gap between platen roller & TPH is not as large as
P1. But still has gap to enable ribbon scrolling through the gap. The
pinch roller touches capstan roller to enable paper loading.
P3 = Print Position
Platen roller close to TPH, paper unmovable. No gap between platen
roller & TPH.

3.1.5.3 Leading Edge Sensor
It’s used to detect the status of paper. Leading Edge will be on when it detects
paper loading; Leading Edge will be off when it doesn’t detect paper loading.
Fig 9. Leading Edge Sensor
3.1.5.4 Jam Sensor
It’s used to detect the status of paper. Jam Sensor will be on when it detects
paper passing; Jam Sensor will be off when it detects paper jam.

3.1.5.5 Ribbon Cassette Sensor
It’s used to detect the type of ribbon cassette and the status of ribbon door.
Ribbon Cassette Sensor will be on if the type of ribbon cassette is correct;
Ribbon Cassette Sensor will be off if the type of ribbon cassette is wrong. In
addition, Ribbon Cassette Sensor will be on if it detects ribbon door is closed;
Ribbon Cassette Sensor will be off if it detects ribbon door is open.

3.1.5.6 Ribbon LED/Ribbon Sensor
It’s used to detect the ribbon status, enable printer to control the ribbon scrolling
correct. Detect ribbon color. In yellow or overcoat layer, ribbon sensor senses
HIGH. In magenta and cyan layer, ribbon sensor senses LOW.

3.1.6 TPH
3.1.6.1 Specification
TPH(Thermal Print Head) is the key component for D2T2 printer, like the inkjet
printing head for inkjet printer. Print data will be shifted into TPH during each
clock. After 384 shift clocks, one line data will be shifted to TPH. Latch/ signal
will latch the print data. Strobe/ signal will heat the corresponding heater
elements on TPH according to shift-in data. More the strobe/ time, more the
dye of the ribbon transfers to paper.
