2.2.3.4 Driving Specifications
Basic control operation
The PG setting in several stages for the Carriage is achieved by moving the CR
Guide Shafts up and down with the DC motor while monitoring with the position
sensors. The control of the DC motor is referred to as Auto PG control (APG
control). The basic operation to realize this control is as follows:
<Setting Control>
To move the CR Guide Shafts from the current PG position to a designated PG position, the DC
1
motor is driven by energization (Duty) according to the time setting, slowed down by receiving
the signal from the sensor 1, and stopped within the PG setting range.
<Reset Control>
By unidirectional energization according to the time setting, the DC motor is driven and stopped
2
at the stopper position. Then PG positions are counted until the Position 1 is reached. Arrival at
the Position 1 is determined when the number of the PG positions is equal to the theoretical value.
APG control operation mode
There are five PG positions, which are determined by a continuous cam profile. Switching
1
between these positions is permitted in sequence: posi.1
The sensor 1 outputs the H and L signals when each PG position area and each area between
2
adjacent positions are detected, respectively. (See the table below for operation modes.)
To set and recognize each PG position area, rotate the motor in the posi.5 direction of the sensor
1 until it is stopped by the stopper. Then rotate the motor back in the posi.1 direction. The five
position areas are recognized in sequence; posi.5
this point, posi.1 is established as the first position. This position flag continues this recognition
3
of the positions until setting of the positions is newly made by a higher sequence.
Each PG position area is set when it is recognized that the signal from the sensor 1 changes as L
→ H (or H → L).
⇔ posi.2 ⇔ posi.3 ⇔ posi.4 ⇔ posi.5
⇒ posi.4 ⇒ posi.3 ⇒ posi.2 ⇒ posi.1. At
Figure 2-13 below shows the relationship between the PG positions and the outputs of
the sensor 1 as well as major applications of the PG positions.

2.2.8 Ink Supply System
The printer is of an off carriage type in which the ink cartridges are contained in the
right and left I/C Holder Assy.
By the Pressure Pump Assy, compressed air is sent through the Pressure Sensor Assy
to the Left Ink Duct Assy. From there, the air is supplied into the left ink cartridges
(x3) and through the Right Ink Duct Assy into the ink cartridges (x3) in the Right I/C
Holder.
The sent air presses the ink bag in each ink cartridge. The ink pushed out is supplied
through the Left/Right Ink Duct Assy → Ink Tube Assy → Valve Assy to the
Printhead.

2.2.8.2 Self-closing Valve
The Valve Assy is equipped with the self-closing valve to prevent ink from flowing
back.
The self-closing valve works as a sub tank to compensate for a temporary shortage of
ink supply to the off carriage type head. When solid printing is performed with a
printhead of an off carriage type, there may be a case where an excessive volume of a
specific ink is consumed temporarily and dot missing can occur.
Use of this valve ensures a uniform print quality.
When ink in the Valve Assy is supplied to the Printhead, the pressure in the Ink Storage
Chamber drops, so that the Valve Lever is tilted by the Pressure Receiving Plate. When
the Valve Lever inclines, the ink passage from the Ink Tube to the Valve Assy opens,
so that ink is supplied to the Ink Storage Chamber.
When the Ink Storage Chamber is filled with ink, the Valve Lever tilted by the Pressure
Receiving Plate is raised, so that the Valve Lever closes the ink passage from the Ink
Tube Assy.
C H E C K

The capacity of each Ink Storage Chamber is equivalent to
printing of 36 pages of graphics.
Stylus Photo RX700 uses six colors, thus two chambers are left

The PWM fundamental period resolution is 24 MHz (= 41.7 nsec), wh ich is taken as
one count. The output time is the ON time, while the remaining time is OFF time.
During the OFF time in PWM driving mode, the slow-decay mode is used with both
the transistors on the sink side turned ON (synchronous rectification is enabled in the
active mode). Unless specified, the motor is stopped by a short brake (duty=0).
The slow-decay mode (chopping OFF time of 50 µsec.) is always used during
current chopping for current control. The slow-decay mode is such that the blanking
time is 6
µsec. and both the transistors on the sink side are turned ON during
chopping OFF in PWM driving mode. (Synchronous rectification is enabled in the
active mode.) The upper limit current value is ± 0.63[A] ± 8%.

Applies pressure to the inside of the ink supply passage. Drives the Pressure
Motor while checking the outputs of the Pressure Sensor and Pump HP
Sensor.
When the Pump HP Sensor turns L → H by the specified number of
additional pumping actions from the state where both sensors are H, the
motor is stopped by a short brake (Duty = 0) via stop control.
Initial pressurization raises the pressure up to above the threshold value of
the Pressure Sensor to reduce the required number of pumping actions.
If “Cover OPEN” is detected during the driving of the Pressure Motor, the
motor is stopped by a short brake (Duty = 0) immediately, without via the
stop control.
Releases the pressure in the ink supply passage to atmospheric pressure. If
the Pump HP Sensor is H, until it turns as H → L → H → L → H, while if it
is L, until it turns as L
continuously and stopped by a short brake (Duty = 0) via stop control.
(The motor is always stopped with the Pump HP Sensor signal at H to avoid
the condition where the bellows pump may creep if it is stopped in a shrunk
position.)

2.3 Operating Principles of Electric Circuitry
2.3.1 Overview
The major circuit boards of Stylus Photo RX700 are as follows:
Main Board: C583MAIN
Power Supply Board: C583PSB/C583PSE
Panel Board: C583PNL
CCD Unit Board (Scanner):
2.3.2 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 (NA85E 2S by NEC) 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).
Equipped with one 256-Mbit SDRAM (16-bit bus width) and one 128-Mbit
SDRAM (16-bit bus width) (two SDRAM in total) for ASIC local buses, and
one 256-Mbit SDRAM (16-bit bus width) for CPU bus.
Two motor driver ICs (RENESAS M63160J) are mounted, each of which
controls two DC motors and one stepping motor.
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.
Equipped with a color LCD (2.5-inch low-temperature poly-silicon TFT
liquid crystal) as a standard feature.
With the aid of the low-current LED, 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 consumption mode
• High η power supply circuit
• Stopping excitation of the printer motor
• 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

4.1 Overview
This section describes procedures for disassembling the main components of the
product.
Unless otherwise specified, disassembled units or components can be reassembled by
reversing the disassembly procedure.
4.1.1 Precautions
See the precautions given under the heading “WARNING” and “CAUTION” in the
following column when disassembling or assembling the product.
Things, if not strictly observed, that could result in injury or loss of life are described
under the heading “Warning”.
Precautions for any disassembly or assembly procedures are described under the
heading “CAUTION”.
Chips for disassembling procedures are described under the heading “CHECK
POINT”.
If the assembling procedure is different from the reversed procedure of the
disassembling, the procedure is described under the heading “REASSEMBLY”.
Any adjustments required after disassembling the units are described under the heading
“ADJUSTMENT REQUIRED”.
When you have to remove any units or parts that are not described in this chapter, refer
to the exploded diagrams in the appendix.
Read precautions described in the next section before starting.
W A R N I N G
Remove the batteries and plug off the AC adapter before
disassembling the Stylus Photo RX700.
Always wear gloves for disassembly and reassembly to avoid
injury from sharp metal edges.
Lithium batteries are installed on the main board of this
product. Never fail to observe the following instructions when
serving the batteries:
1. Keep each battery away from any metal or other batteries so
that electrodes of the opposite polarity do not come in contact
with each other.
2. Do not heat the battery or put it near fire.
3. Do not solder on any part of the battery. (Doing so may result
in leakage of electrolyte from the battery, burning or
explosion. The leakage may affect other devices close to the
battery.)
4. Do not dismantle the battery. (The gas inside the battery may
hurt your throat. Leakage, burning or explosion may also be
caused.)
5. Do not install the battery in the wrong direction. (This may
cause burning or explosion.)
6. Dispose the used batteries according to government's law and
regulations.
7. To avoid dust explosion or ignition, never heat batteries or
bring them close to flames or throw them into fire.
To protect sensitive microprocessors and circuitry, use static
discharge equipment, such as anti-static wrist straps, when
accessing internal components.
Disassembly and Assembly Overview 77

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 disassem bly 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.
