Note 1: For both PC connection and Directing printing, only one type of media is accessible at the same time.
Priority is assigned to each slot, so that if multiple media are inserted into multiple slots at the same time, an accessible slot is determined in the order of priority.
2: In order to select the medium inserted into an invalid slot, the medium in the valid slot needs to be removed.
3: For direct printing: Only the image files in a valid slot are determined to be valid and photo numbers are assigned to only them. The number of images does not change
even if media are inserted into unselected slots.
4: For PC connection (Windows): Only one “removable disk” drive is displayed; and only the medium in a valid slot can be accessed on the “removable disk.” Media inserted in
unselected slots are not accessible.
5: For PC connection (Macintosh): Only the medium in a valid slot is mounted onto the desktop. Media inserted in unselected slots can not be mounted onto the desktop.
6: Slot selection at power on: When power is turned on with media inserted in multiple slots, an accessible slot is determined in accordance with the above order of priority.
7: Slot selection with power turned on: When the medium is removed from the valid slot, the slot of the second highest priority becomes valid (if a medium is inserted there). It is not
necessary to reinsert the medium before it is accessed. If media are not inserted in any of the slots, the valid slot is changed to the slot of the highest
priority (Compact Flash). This is not affected by the order of media insertion in or removal from unselected slots.

2.2 Operating Principles of Electric Circuitry
2.2.1 Overview
The major circuit boards of Stylus PHOTO RX640/650 are as follows:
Main Board: C608MAIN
Power Supply Board: C608PSB/C608PSE
Panel Board: C608PNL and C608PNL-B
CCD Unit Board (Scanner): C608ISN
USB I/F Board : I/F Board Assembly
2.2.2 Features
High-Speed SPC is realized without HUB, thanks to employment of USB 2.0
multi-end point.
An SOC incorporating the printer controller, scanner controller, PT controller
and CPU Super Macro is realized.
Only one CPU (SH2A by RENESAS) controls the printer, scanner and PT
section.
Equipped with one 64-Mbit Flash ROM (with 16-bit bus width) and one 32-
Mbit Flash ROM (with 16-bit bus width).
(Flash ROM or MASK ROM is mounted)
Equipped with one 256-Mbit SDRAM (16-bit bus width) for ASIC local
buses, and one 256-Mbit SDRAM (16-bit bus width) for CPU bus.
Low cost of logic power supply and motor drive is realized by employment of
motor drivers with built-in power supply.
The band width is ensured by setting the operating frequency of the local
SDRAM of SOC at 96 MHz.
High-speed processing is ensured because all the processing from scanning to
binarization, Microweave, and image buffer generation is carried out inside
the SOC, without via the CPU bus.
The size of the MW buffer is reduced to 1/3 of the conventional size by
employment of UBEC (Ultra Block Encode).
Equipped with a color LCD (2.5-inch low-temperature poly-silicon TFT
liquid crystal) as a standard feature.
Power consumption is suppressed by executing the following actions at
transition to the power save mode.
• Lowering the supply voltage for main power
• Cutting off the photo-electric current of the photo sensor
• Stopping the motor drive circuit
• Stopping the UDL clock inside the ASIC
• Entering the CPU core low consump tion mode
• High efficiency power supply circuit
• Stopping excitation of the printer mot or
• Stopping the head drive circuit
• Turning off the CCD scanner power supply and stopping the excitation of the
scanner motor
• Turning off the preview monitor

Disassembly and Assembly Overview 41
Remove the batteries and unplug the AC adapter before
disassembling the Stylus PHOTO RX640/650.
Always wear gloves for disassembly and reassembly to avoid
injury from sharp metal edges.
To protect sensitive microprocessors and circuitry, use static
discharge equipment, such as anti-static wrist straps, when
accessing internal components.
When the Main Board is to be replaced, make a copy of the EEPROM data.
When the Carriage Assy is to be moved out of its home position, locate it at a
position other than the home position before starting disassembly by turning the
power ON and turning it OFF timely.
As soon as the repaired product has been returned to the user, there may be a case
a maintenance call occurs because of the expiration of the life of a service part.
Avoid such a case, if possible, as follows: Check the maintenance counter for
regularly replaced parts before disassembly. If the life of any part is found almost
expired, communicate with the user to that effect. If the user's consent is obtained,
replace also the relevant service parts with new ones.
