Note the following caution points when handling the memory card. Since the SD card and Memory Stick share the same slot, only
one can be inserted at a time.
Since the SmartMedia and xD-Picture Card share the same slot,
only one can be inserted at a time.
When a memory card is being accessed, be sure to keep the
memory card slot’s cover closed and do not touch the memory card.

NOTE 1: 3.3V power is supplied to media that support both 3.3V and 5V.
2: Maximum current to memory card is 500mA.
3: 5V type memory cards are not supported.

1.3.3 Multi-slot Operations

Overview
Only one type of card can be used to simultaneously access both a connected
computer and the direct printing function.
The slots have assigned priority to determine which slot will be accessed first
when cards are inserted in several slots at once.
To select a card that has been inserted in a non-active slot, the card in the
active slot must first be removed.
• Direct printing: Only the image files in the active slot are valid and have assigned frame numbers. The number of images will not change if a card is also inserted in a non-selected slot.
• Connection to computer (Windows): Only one drive is displayed at a time as a “removable disk” and only the card that is in the active slot can be accessed via the removable disk. A card that has been inserted into a non-selected slot cannot be accessed.
• Connection to computer (Macintosh): Only the card in the active slot can be mounted on the desktop. A card that has been inserted into a non-selected slot cannot be mounted on the desktop.
Details
Access priority
The access priority among slots is assigned as: 1: CF (Micro Drive) 2: Smart Media / xD-Picture Card 3: Memory Stick (Memory Stick PRO) / SD (MMC)
Slot selection when power is turned on
If cards are inserted in several slots when the power is turned on, the active slot is determined by the priority ranks listed above.
Example: If Smart Media and Memory Stick are both inserted at power-on,
the Smart Media slot becomes the active slot.
Slot selection after power is turned on
When a card is removed from the active slot, the slot with the next-highest priority becomes the active slot (if a card has been inserted into it). There is no need to re-insert any card before accessing it. If no slots contain any cards, the highest-priority slot (CF Micro Drive) again becomes the active slot. Cards can be removed from non-selected slots in any order.
Example: If a memory stick and CF card are inserted while Smart Media is
selected, CF becomes selected (active) once Smart Media is removed.

1.5.1.1 File System
DCF Version 1.0 or 2.0 is the file system that can be used with this unit’s stand-alone printing functions. Operation is not guaranteed when any other file system is used. The file system used by the card reader function depends on the host’s specifications. For a detailed description of the DCF specifications, see the “Design Rule for Camera File System Standard, DCF Version 2.0, JEIDA-CP-3461”.
1.5.1.2 Media Format
Media must be formatted according to the DCF Version 1.0 or 2.0 standard.DOS FAT formats (FAT12, FAT16) and single partition (basic partition)
1.5.1.3 File Formats
The file formats supported by this unit are described below. JPEG files (*.JPG)
These are photo data files that comply with the Exif Version 2.21 standard. (Exif version 1.0/2.0/2.1/2.2/2.21)
Camera specification files (*.MRK)
These are definition files used when in camera specification mode. An “AUTOPRINT.MRK” file whose full path name is no longer than 32 characters is valid.
PRINT Image Framer (P.I.F) definition file (*.USD)
File to define the layout in accordance with the PRINT Image Framer specifications. Files only in the “
Compatible with Print Image Framer Rev. 2. 1.
¥EPUDL¥” directory are available.
PRINT Image Framer (P.I.F) definition file (*.FD2)

. All files in the memory card are targeted for search.
Compatible with Print Image Framer Rev. 3. 1.
File contents are divided into complete type and template type.
Template Type: The frame only on which image data is printed is
specified. Provides nearly identical functions as those supported with the current P. I. F. Rev. 3. 1.
Complete Type: Print layout information, image data, and frame data is
contained in one package. Printing is performed using this file only without specifying photos.
Note, however, any file that is saved in the following directories or their sub-directories cannot be included as files to be printed.
Directories containing system properties or hidden properties
Directories that contain any double-byte characters in the directory name
“RECYCLED”: Windows directory for deleted files
“PREVIEW”: Directories containing CASIO’s DSC thumbnail
images

Shot function
“MSSONY”: Directories containing SONY’s DSC e-mail image
data, voice memos, video files, or non-compressed images
“DCIM
¥ALBUM¥IMAGE”: CASIO DSC album data save directory
1.5.1.4 Valid Image Size
The maximum image size handled by this unit is:
Horizontal: 80 X 9200 (pixels)
Vertical: 80 Y 9200 (pixels)
PRODUCT DESCRIPTION Memory Card Print 33
EPSON Stylus Photo RX520/RX530 / Stylus CX7700/CX7800 Revision D
1.5.1.5 Maximum Number of Photo Data Files
This unit can handle up to 999 photo data files. If the amount of photo data to be recorded exceeds the capacity of one memory card, this unit uses file sorting rules to sort the photo data into valid photo data in frames numbered from 1 to 999. Although it is possible to print photo data files with frame numbers over 999 that have been specified for printing by camera specification files, the maximum number of frames that can be specified is 999 frames. If you insert a memory card that contains over 999 photo data files, only files up to 999 will be printed by the “Print All” or “Print index sheet” functions.
1.5.1.6 Thumbnail Image Data
This unit handles thumbnail image data in the DCF Version 1.0 or 2.0 format (Exif format, 160 x 120 pixels). During this unit’s Index sheet and memory card printing modes, the layout is 80 thumbnails per sheet (when using plain paper or special paper in high-speed print mode).
1.5.1.7 File Sorting
This unit stores all photo data files in the memory, using the photo data files’ full-path file names (for example, “\DCIM\100EPSON\EPSN0000.JPG”), and assigned photo frame numbers. Since photo frame numbers are assigned based on this unit’s own proprietary file sorting rules, the assigned frame numbers do not necessarily match those indicated by digital cameras.
1.5.1.9 Rules for Acquisition of Date/Time
The following priorities are used to fetch date and time information from photo data files.
1. Date/time data that complies with the standard format (Exif) for digital cameras
2. Date/time data that complies with the DOS standard file system (file time stamps)
3. Fixed values (01/01/1980, 00:00:00)
Note that the date/time data assigned to individual photo data files does not necessarily match the date/time when the photo was actually taken. The photo date/time may be modified due to the digital camera’s calendar settings (presence/absence of functions, incorrect date/time settings, etc.), processing of the photo data after the photo was taken, or subsequent saving of data. In such cases, this unit performs the relevant processing based on the most recently modified date/time data.
1.5.1.10 Number of Sheets which can be Printed in Total
Printing sum total number of sheets presupposes that it is possible to 999 sheets. Moreover, the printing sum total number of sheets per sheet is possible to 99 sheets.
1.5.1.8 File Sorting Rules
This unit sorts photo data files based on the following prioritization rule.
File name is sorted in ASCII order as full path name.
NOTE: Sorting results are not guaranteed if two files have matching full-path file
names. (Matching full-path file names are not allowed under the DOS specification.)

1.5.3.1 Rules for Scanning Index Sheets
Index sheet scan range
Set index sheet in scanner
• Place the side to be scanned face down relative to the scan bed, as described below. Align the corner of the sheet to the upper left origin point and make sure the sheet is straight. Angled setting of the sheet is allowed as long as the sheet remains within the scan bed’s scan range (the maximum angle on the scan bed is about 2.8°).
• The cover must be closed on the original to enable scanning. (This is to prevent any shifting of the position marks while scanning).
• Do not use paper that allows images to “bleed through” to the rear side. (This is to prevent empty bubbles from being filled in by “bleed-through”.)

• When two or three marks of one image are filled, larger number will be used for the number of copies. (ex. 1 and 3 are filled, number of copies is 3.)
• When the optional “ALL” mark is filled, all images in the sheet will be printed one by one regardless of each image mark is filled or not.
• Index sheet error will be caused when any of image mark or “ALL” mark is not filled.
• Index sheet error will be caused when “Left top triangle”, “Right top EPSON” and “Block codes” are not found correctly due to something like smear.
• Place the index sheet so that the “Left top triangle” can meet the left top corner of the scanner.
Errors during scanning or printing of index sheets
• Stops scanning and returns to the menu screen if the card is removed while an index sheet is being scanned or printed.
• Index sheet error (No index sheet) is displayed if the sheet cannot be scanned because it is dirty, set backwards, etc.
• Index sheet error (Incorrect marking) is displayed if the image bubbles cannot be read because they are not filled in correctly.
• Index sheet error (Incorrect card) is displayed if, after printing an index sheet, you try to print from a non-matching memory card, such as a different (replacement) card or a re-edited version of the same card.

• The marks can be recognized if 50 % or more portion of each of them is filled.
• For running out and excessive marking out, the two white/black search patterns shown above are superimposed on the mark, and judgment is made according to this matching ratio. The judgment criteria is as follows. Black matching: 80 % or more White matching: 50% or more.

1.5.6 Trimming Function

A trimming function is provided as a means of coordinating photo data with the types of photo frames handled by this unit. This function is always activated so that printing photo data is in shapes that fit these photo frames. This function is described briefly below. The printed photo frame and the photo to be printed are matched in length along one side and the photo is resized along the perpendicular side to fit the frame on that side. Any part of the photo that does not fit within the photo frame is trimmed away (not printed).
The image below shows an example in which the photo data is aligned vertically
with the photo frame.
These parts are trimmed.
The image below shows an example in which the photo data is aligned
horizontally with the photo frame.
Photo frame (print area)

1.5.7 Assignment Rules for Photo Frame Numbers and Rotation

The rules concerning photo frame numbers that are referenced when assigning photos are described below. The numbers shown in each diagram and photo frame below indicate the photo frame numbers used for various types of layout. The direction of the number shown in each photo frame matches the direction of the printed photo to which the horizontal photo data was allocated. When there are more pixels vertically than horizontally, the vertical photo data is allocated instead, and the number shown in the figure below is then rotated 90° before being printed. In Index printing mode, the numbers are printed as they are shown below, regardless of the shape of the photo data. However, when the photo data has an equal number of pixels vertically and horizontally the photos are printed without rotation, regardless of the layout.
NOTE: The vertical photo data refers to when the photo data file itself is set for a
vertical (portrait) orientation. Photo data is defined as the vertical photo data if it is taken by a digital camera with a portrait position detecting function.

Nozzle layout
Black : 90 nozzles x 1 row
Color : 90 nozzles x 3 row/color (Cyan, Magenta, Yellow)

The basic operating principles of the Printhead, which plays a major role in printing, are the same as the previous printer; on-demand method which uses PZT (Piezo Electric Element). In order to uniform the ejected ink amount, the Printhead has its own Head ID (13-digits code for this Printhead for Stylus Photo RX520/RX530/Stylus CX7700/CX7800) which adjusts PZT voltage drive features. So, you are required to store the Head ID pasted on the Printhead into the EEPROM by using the Adjustment Program when replacing the Printhead, the Main Board Unit, the Printer Mechanism with new one. (Note: there are no resistor arrays to determine the Head ID on the Main Board.) And then, based on the stored Head ID into the EEPROM, the Main Board generates appropriate PZT drive voltage.
Following explains the basic components for the Printhead.
PZT
PZT is an abbreviation of Piezo Electric Element. Based on the drive waveform generated on the Main Board, the PZT selected by the nozzle selector IC on the Printhead pushes the top of the ink cavity, which has ink stored, to eject the ink from each nozzle on the nozzle plate.
Electric poles for CSIC
This Electric Poles connects the CSIC chip mounted on the Ink Cartridge. By using this poles, current ink consumption amount data is red out from the CSIC chip. And, the latest ink consumption amount data is written into the CSIC chip.
Nozzle Plate
The plate with nozzle holes on the Printhead surface is called Nozzle Plate.
Filter
When the Ink Cartridge is installed, if any dirt or dust around the cartridge needle is absorbed into the Printhead, there is a great possibility of causing nozzle clog and disturbance of ink flow, and alignment failure and dot missing finally. To prevent this problem, a filter is set under the cartridge needle.
OPERATING PRINCIPLES Printer Mechanism 74
EPSON Stylus Photo RX520/RX530 / Stylus CX7700/CX7800 Revision D
Ink Cavity
The ink absorbed from the Ink Cartridge goes through the filter and then is stored temporarily in this tank called “ink cavity” until PZT is driven.

2.2.2.1 Printing Process
This section explains the process which the Printheads of On-Demand inkjet printers eject ink from each nozzle.
1. Normal state: When the printing signal is not output from the Main Board (C613 Main), or the PZT drive voltage is not applied, the PZT does not change the shape. Therefore, the PZT does not push the ink cavity. The ink pressure inside the ink cavity is kept normal. (refer to Figure 2-4 (p.75): Normal state)
2. Ejecting state: When the print signal is output from Main Board (C613 Main), the nozzle selector IC located on the Printhead latches the data once by 1-byte unit. Based on the drive waveform (common voltage) generated on the Main Board, the PZT selected by the nozzle selector IC pushes the top of the ink cavity. By this operation, the ink stored in the ink cavity is ejected from nozzles. (refer to Figure 2-4 (p.75): Ejecting state)

2.2.2.2 Printing Method
The dot printing systems of Stylus Photo RX520/RX530/Stylus CX7700/CX7800 are variable dot printing systems.
Variable dot printing
This printing mode is developed to improve the print quality on exclusive paper. This mode is basically the same as variable dot printing mode used on other products; micro dot, middle dot and large dot compose this mode. The printing dot size varies according to the print data and this mode enables to output even sharper image on exclusive paper.
Economy dot printing
Economy dot printing is basically used only during Economy mode printing. The reason is that the resolution is low during Economy mode printing, so that the dot size needs to be bigger.

2.2.3 Carriage Mechanism

The Carriage Mechanism consists of Carriage Unit (including the Printhead, CR Encoder Board and PW Sensor), CR Motor, Timing Belt and CR Scale etc. Following figure shows you each component for the CR Mechanism.
2.2.3.1 Carriage Mechanism
The following DC motor controls the CR Mechanism on this printer.
Table 2-1. Carriage Motor specification
Items Specifications
Type DC motor with brushes
Drive Voltage 42V (DC) ± 5% (voltage applied to driver)
Armature resistance 29.1 ± 10%
Inductance 20.1mH ± 25%
Drive Method PWM, constant-current chopping
Driver IC A6627
Close loop control based on the CR Motor (DC Motor) and CR Encoder has advantages in stabilized print quality.
Heat generation control
Using low-cost DC motors, this product grasps the variations of the torque constants, coil resistances and power supply voltages of the individual DC motors adequately to carry out heat generation control according to individual differences.
CR measurement sequence
To set the appropriate drive current value according to the variation of the CR mechanical load, the mechanical load is measured in a CR measurement sequence and saved into the EEPROM in a power-on or I/C change sequence. A fatal error will occur if too much load is applied to the CR drive system.
The above control and sequences correct the drive current value of the CR Motor according to not only the mechanical load but also the variations of the motor and like. In addition, the resultant CR drive current value is used to calculate a heating value, and when the specified heating value is reached, wait time is provided per CR path for printing.

2.2.3.2 Carriage Home Position Detection
Like other conventional models, the carriage home position is detected using the CR Motor drive current and the CR Encoder speed/position signals. Fundamental home position detection sequence is described below.
1. Current position temporary detection sequence determines if the carriage is in the carriage lock position and releases the carriage if it is locked.
2. The carriage is moved to the left frame hit position and the carriage motor is stopped.
3. The position that is specified steps right from the stopping place is defined as an origin, and from that time, positional information is monitored by the linear encoder.
If the positional information could not be gained during detecting carriage home position due to the following causes, fatal error occurs.
• Obstructions on the carriage path or other factors are giving too much pressure
on the CR motor.
• CR Encoder failure, CR Scale defect, etc.
2.2.3.3 Sequence Used for PW Detection
The PW (paper width detection) Sensor installed on the Carriage Unit bottom is used to control the printer according to various sequences.
The following briefly describes the PW Sensor operating principle.
A dark voltage is measured by the PW Sensor in three places on the right end plane (area without the absorber) of the Front Paper Guide every time power is switched on, and the measurement values are saved into the EEPROM as threshold values.
Threshold value > detection voltage: Paper present
Threshold value < detection voltage: Paper absent
The following sequences are performed.
Paper Left/Right Edge Detection Control
Before start of printing (immediately after the end of paper locating), or during printing, whether paper is present or not is detected to prevent off-paper printing on the Paper Guide by borderless printing used in a wrong way.
Paper Top Edge Detection Control
Detects paper leading edge at start of printing. Also sets the amount of extension for the paper leading edge during borderless printing.
Paper Bottom Edge Detection Control
Sets the amount of extension for the paper trailing edge during printing.

For your reference, the top or the end of a paper is usually detected with the PE Sensor. In case that the PE Sensor cannot detect the top of a paper in the paper loading sequence, the printer indicates the “Paper Out error”. If the PE Sensor cannot detect the end of a paper in the paper feeding sequence, the printer indicates the “Paper Jam error”. As for the details, refer to Chapter 3 “Troubleshooting”.
2.2.4.1 Paper Loading Mechanism
The Paper loading mechanism consists of the Change Lever in the Pump Unit, the Holder Shaft Unit (including the Clutch mechanism) and the ASF Unit. The Change Lever and the Clutch mechanism play a major role in the Paper loading mechanism as follows.
1. ASF home position detection function The ASF Unit on this printer does not have the ASF Home Position Sensor. Instead of the ASF Home Position Sensor, the Change Lever and the Clutch mechanism is used to detect the ASF home position. When the Change Lever is set on the Clutch mechanism with the counterclockwise rotation of the PF Motor pinion gear, the ASF home position is detected by this lever for the paper loading operation. In this time, the printer cannot load a paper from ASF Unit because the drive of the PF Motor is not transmitted to the LD Roller Shaft.
2. Paper loading function When the Change Lever is released from the Clutch mechanism with the clockwise rotation of the PF Motor pinion gear, the ASF home position detection function is changed over to the paper loading function. Therefore, the printer can load a paper from ASF Unit because the drive of the PF Motor is transmitted to LD Roller Shaft.
During paper loading, paper is transported from the ASF Unit into the printer by the rotation of the 2 cams of the LD Roller.
Cam (Large) : Hopper release
Cam (Small) : Paper Back Lever release
When 1 page paper is loaded, the cams mentioned above prepare the Hopper and Paper Back Lever for the next paper loading operation, and the remaining paper is returned to the standby position.
Figure 2-7 (p.80) and Figure 2-8 (p.81) show you the ASF paper loading sequence and
the operation of each mechanism.
OPERATING PRINCIPLES Printer Mechanism 79
EPSON Stylus Photo RX520/RX530 / Stylus CX7700/CX7800 Revision D
When the PF Motor pinion gear rotates CCW direction (right side view), the Change Lever pushes down the Clutch lever as right figure and the Clutch lock tooth is disengaged from the Clutch Gear. As the result, the LD Roller Shaft dose not rotate at all because the drive of the PF Motor is not transmitted. In this time, the Hopper is also pushed down by the two cams on the LD Roller Shaft, and the Paper Back Lever is set to avoid that papers are slipped down from the paper set position.
This position is the ASF home position.

When a paper is loaded from the ASF Unit, the Change Lever moves to the front side of the printer with the CW rotation (right side view) of the PF Motor pinion gear and releases the Clutch lever. As the result, the Clutch turns back to the engagement position by the tension force of the Extension Spring 0.143. And, the Clutch gear is engaged with the Clutch lock tooth to transmit the drive of the PF Motor as left figure. In this time, the Change Lever is locked instantaneously by the protrusion on the backside of the Carriage Unit to change over from the ASF home position detection function to the paper loading function surely.

The PF Motor pinion gear rotates CCW direction (right side view), and the drive of the PF Motor is transmitted to the LD Roller Shaft through the Clutch lock tooth and the Clutch gear. After the LD Roller pushes down the Paper Back Lever into the ASF Frame, the Hopper is released by the tension force of the Compression Spring 5.58. And, a paper is picked up with the frictional force between the LD Roller and the Pad Hopper.

time, this lever returns papers to the stand-by position in ASF Unit for next paper loading operation. Then, when the rolling LD Roller & the Clutch come at the above “Step1” position, the Clutch lever is locked with the Change Lever again. In this time, the drive of the PF Motor is interrupted and the drive is transmitted only to the PF Roller side for the paper feeding sequence.

2.2.5 Ink System Mechanism

The Ink System Mechanism consists of Pump mechanism with Carriage lock mechanism and Capping mechanism with Wiper mechanism. Following table lists the function for each mechanism.
Table 2-4. Function for each mechanism
Mechanism Function
Capping mechanism *
Wiper mechanism
Pump mechanism
Carriage lock mechanism
Note "*" : Like the previous printers (Stylus Photo R300/R310), this printer adopts the
valveless cap system. The air valve system used for the previous printer (Stylus COLOR 740) have two functions by the CR position in the capping condition as follows.
This is to cover the surface of the Printhead with the cap in order to prevent the nozzle from increasing viscosity.
This is to remove the foreign material and unnecessary ink on the nozzle plate of the Printhead.
This is to eject the ink from the Ink Cartridge, the ink cavity and the cap to the Waste Ink Pad.
This is to lock the Carriage Unit with the Change Lever while the Carriage Unit is at the home position.
1) Valve closing condition (CL position) By closing the air valve, the ink is forcibly absorbed from the Ink Cartridge or the ink cavity by the Pump Unit and is ejected to the Waste Ink Pad while the Carriage Unit is in the CL position.
2) Valve opening condition (Ink absorption position) By opening the Air valve, the negative pressure is decreased and only the ink inside the Cap is ejected while the Carriage Unit is in the further right side than the CL position. (the ink is not absorbed from the Ink Cartridge or the ink cavity.)
The following shows you the Carriage Unit position for each condition easily.
Printing area CR home position
CL position (valve closing condition)
Ink absorption position (valve opening condition)
But, on the valveless cap system, the above 2) operation is done outside the capping position. The Carriage Unit moves outside the CR home position and the pump absorbs the ink inside the Cap.

EPSON Stylus Photo RX520/RX530 / Stylus CX7700/CX7800 Revision D
2.2.5.1 Capping Mechanism
The Capping mechanism covers the Printhead with the Cap to prevent the nozzle from increasing viscosity when the printer is in stand-by state or when the printer is off.
When the Carriage Unit is in the home position, the hook of the Slider Lock Lever is not latched to the dent of the Cap Frame. In this time, the protrusion of the Cap Slider Lever does not reach the rightmost position of the Cap Frame.
Capping position (CR home position)
Step 1
Protrusion
Not latched
Wiper with the Cap unit
The wiping operation is controlled by the Carriage Unit movement. This operation is usually performed with every CL sequence which is to absorb the ink from the ink cartridge, the ink cavity by the Pump unit. Following figure shows you the mechanism for the wiping operation.
Step 2
The Carriage Unit moves to the Wiper setting position on the rightmost position of the Cap Frame with keeping the Cap covered. In this time, the hook of the Slider Lock Lever is latched to the dent of the Cap Frame.
Latched
Wiper setting position
When the Carriage Unit moves to the left side from the Wiper setting position, the Cap Unit is pulled back by the tension force of the
Spring 0.788
.
Extension
In this time, the Cap Unit is automatically set to the wiping position because the hook on the Slider Lock Lever is latched to dent of the Cap Frame. And, the wiping operation is performed according to the Carriage Unit movement.
Step 3 Step 4
Protrusion of the Carriage Unit

Released position (Bottom position)
When the wiping operation is finished and the Carriage unit moves further to the left side, the hook of the Carriage unit hits to the Slider lock lever. In this time, the Slider lock lever is released and the Cap slider returns to the bottom position completely. (The broken line is the position of the Carriage unit & the Slider lock lever just before being released.)

2.2.5.2 Pump Unit Mechanism
The PF Motor also controls the Pump Unit mechanism (including the Change Lever) as well as the Paper loading/feeding mechanism. The drive of the PF Motor is always transmitted to the Pump Unit. (And also, its drive is transmitted to the LD Roller through the Clutch mechanism & the Change Lever.) On this printer, the Pump Unit mechanism including the Change Lever plays a major role expecting the ink eject operation. And, these operations control depending on the PF Motor rotational direction as the following table below.

2. Carriage lock operation by the Change Lever Unlike the previous printer (Stylus COLOR 680), this printer does not have the Carriage Lock Lever with the Wiper. Instead of the Carriage Lock Lever, the Change Lever is set to the front side of the printer while the Carriage Unit is in the CR home position. (As for the detailed mechanism for setting the Change Lever, refer to Figure 2-7
(p.80) Step 2)

2.2.6 Ink Sequence

Initial ink charge
After the printer is purchased and the power is turned on for the first time, the printer must perform the Initial Ink Charge to charge the ink inside the ink cavity. When the Initial Ink Charge is completed properly, the printer releases the flag inside the EEPROM. Initial Ink Charge will take about 114 seconds for Stylus Stylus Photo RX520/RX530/Stylus CX7700/CX7800. If the power is turned off during the Initial Ink Charge, the CL3 will be performed at next power on timing.
Manual Cleaning
The Stylus Photo RX520/RX530/Stylus CX7700/CX7800 provides three types of manual cleaning to clean air bubbles, clogged ink with viscosity or foreign substances. The manual CL can be performed by the Control Panel Operation, the Printer Driver Utility and the Adjustment Program.
CL1
• Ink absorption (Maximum) Black Ink: 0.163g, Color Ink: 0.488g
• Wiping operation Wipes the nozzle plate by the rubber part on the Cap Unit.
• Flashing operation Prevents color from mixing, and stabilizes ink surface inside the nozzle.
CL2
• Ink absorption (Maximum) Black Ink: 0.470g, Color Ink: 1.410g
• Wiping operation Wipes the nozzle plate by the rubber part on the Cap Unit.
• Flashing operation Prevents color from mixing, and stabilizes ink surface inside the nozzle.
CL3
• Ink absorption (Maximum) Black Ink: 1.073g, Color Ink: 3.218g
• Wiping operation Wipes the nozzle plate by the rubber part on the Cap Unit.
• Flashing operation Prevents color from mixing, and stabilizes ink surface inside the nozzle.
OPERATING PRINCIPLES Printer Mechanism 86
EPSON Stylus Photo RX520/RX530 / Stylus CX7700/CX7800 Revision D
Independently of the printing path after the previous CL, perform manual CL from CL1 to CL3 in order if the cumulative printing timer counter is less than 9min. Only when the cumulative printing timer counter is more than 9min, execute only CL1. Additionally, if the I/C is Ink Low or Out condition, any manual cleaning is prohibited and error display is indicated on the LCD.
Timer Cleaning
Like the previous printers, this printer dose not have Lithium battery which is used for the backup power source for Timer IC. So, this printer manages the printer off period or cleaning cycle by using the following method. The Printer Driver sends the timer command to the printer before printing. The timer command is generated based on the PC’s timer and it consists of year, month, date, hour, minute and second. As soon as the printer receives the timer command from the Printer Driver, the printer stores its command in address 06<H> and 07<H> in the EEPROM. Then, it is compared with the latest CL time which is stored in address 04<H> and 05<H> in the EEPROM. And, In case that the timer cleaning period is over the specific period, the printer performs the timer cleaning automatically. In this time, the printer stores the timer command in address 04<H>, 05<H>, 06<H>, 07<H> in the EEPROM. Maximum 3.55g of the ink is consumed in the timer cleaning. (0.888g of black ink and 2.663g of color ink are consumed.)
Flashing
Two different flushing operations are executed for the following reasons.
Pre-printing flushing
This is done before a start of printing to eliminate ink viscosity in the Printhead nozzles.
Periodic flushing
This is done during printing to prevent ink viscosity in the Printhead nozzles from increasing.

2.3 Scanner Mechanism

The Scanner Mechanism of Stylus Photo RX520/RX530/Stylus CX7700/CX7800 is constructed of a Scanner Carriage Unit, Scanner Motor, Scanner HP Sensor, etc., in the same way as previous A4 size scanners.

2.3.1 Scanner Carriage Mechanism

2.3.1.1 Scanner Carriage Unit Overview
The Scanner Carriage Unit is constructed of a CIS Board (including linear CCD), Rod Lens Array, TPU Inverter Board, Lamp (light source), etc.
CIS Board
This takes the light information read from the document by the Rod Lens Array and converts it to digital information using the linear CCD.
Rod Lens Array
Many rod-shaped lenses are arranged in parallel, and the upright multiple images of each lens is overlapped to form a single continuous image. Compared to a regular lens, this has the special ability to reduce the distances between images. It can project at 1 to 1 size for imaging a linear CCD with a width identical to an A4 size document.

2.3.1.2 Scanner Carriage Unit Movement Overview
Scanning image is performed in the main scan direction (=1 line) by the CCD sensor and in the sub-scan direction (=several lines) combined with Scanner Carriage Unit movement. (refer to the figure below) Line type, color CCD sensor can scan 1 line in main scan direction (parallel to the Scanner Carriage Unit) by one time. When scanning next lines after the second line in sub-scan direction, CR driving moves the Scanner Carriage Unit, which has CCD sensor inside, and scan the other lines. The scanned data is sent to the control board. The scanned data for “n” lines and “n-1” line are processed consecutively.

Adoption of 3.3V/1.5V drive logic circuit components
The 5V formed by the Regulator (IC13) of C613 Main Board is stepped down to
3.3V by the Regulator (IC6), and it is then used as drive voltage for many elements. In addition, when SPC shifts to low power mode, the 3.3V that was stepped down by the Regulator (IC6) is stepped down to 1.5V by the Motor Driver (IC5) and elements that had been driven by 3.3V are driven by 1.5V for suppression of power consumption.

2.4.2.2 Printhead Driver Circuit
The Printhead driver circuit consists of the following two components:
Head common driver circuit (Common driver IC7 & Wave amplifier
transistor Q3, Q4)
Nozzle selector IC on the Printhead driver
The common driver (IC7) generates a basic drive waveform according to the output signals from CPU (IC8). The basic drive waveform is amplified by the transistors Q3 and Q4 (the amplified one is called drive waveform.) and then transferred to the nozzle selector IC on the Printhead driver board. Print data is converted to serial data by the CPU and then sent to the nozzle selector IC on the Printhead driver board. Based on the serial data, the nozzle selector IC determines the nozzles to be actuated. The selected nozzles are driven by the drive waveforms amplified by the transistor Q3 and Q4. Refer to Figure 2-20 (p.95) for the Printhead driver circuit block diagram.
Head common driver circuit
The basic drive waveform is generated in the common driver (IC7) based on the following 13 signal lines output from the CPU (IC8); DATA0-DATA9, LAT, RESET, and PSCNT. By the DATA signal output from the CPU, the original data for the basic drive waveform is written in the memory in the common driver (IC7). The addresses for the written data are determined by DATA0-DATA9 signals. Then, the necessary data is selected from the address and appropriate basic drive waveform is generated. Generated basic drive waveform is transferred to nozzle selector IC on the Printhead driver board through the transistor Q3 and Q4 and applied to the nozzle PZT specified by nozzle selector IC.
Nozzle selector circuit
Printing data is allocated to the four rows (the number of the head nozzle rows) and converted into serial data by the CPU (IC8). Then the converted data is transferred to the nozzle selector IC through the four signals lines (HS01 to HS04). Data transmission from the CPU to the nozzle selector synchronizes with the LAT signal and SCK clock signal. Based on the transmitted data, appropriate nozzle is selected and the PZTs of the selected nozzle are driven by the drive waveform output from the head common driver.

2.4.2.3 Motor Driver Circuit
CR/PF Motor drive circuit
The motor driver IC (IC5) on the Main board drives CR/PF Motor. This product uses DC motor and performs constant current PWM drive. Based on the output pulse (signal) from CR Encoder or PF Encoder, the CPU (IC8) sets the appropriate drive current value for each operational action and outputs the value as a special control signal to the Motor Driver (IC5). Then, based on the signal output from the CPU, the Motor Driver outputs the motor drive current to the CR/PF Motor. When no data has been received for 5 minutes, the CPU sets the Motor Driver current value to 0, turning off the Motor Driver, in order to conserve electricity.
Scanner Motor Driver Circuit
The motor driver IC (IC9) on the Main board drives Scanner Motor. This product uses PM type stepping motor and performs constant current bi-polar drive. The Motor Driver IC (IC9) forms the motor drive waveform based on the signal output from the CPU (IC8), controlling the Scanner Motor. When no data has been received for 5 minutes, the CPU sets the Motor Driver current value to 0, turning off the Motor Driver, in order to conserve electricity.

2.4.2.4 Combination Circuit
This printer differs from previous models by using a combination IC that integrates the reset circuit, EEPROM and RTC.
Reset Circuit
RTC IC (IC4) on the Main Board monitors the three voltage: +3.3V for the logic line, +5V for the logic line and +42V for the drive line. Reset Circuit outputs the reset signal to CPU (IC8) in the following case.
+3.3V line reset circuit
The 3.3V line is monitored at the VDD port of IC4, and if an abnormal voltage is detected, a reset signal for the CPU is output from the FRST port ofIC4.
+5V line reset circuit
The 5V line is monitored at the VDD2 port of IC4, and if an abnormal voltage is detected, a reset signal for the CPU is output from the RST port of IC4.
+42V line reset circuit
The 42V line is monitored at the VEX port of IC4, and if an abnormal voltage is detected, a reset signal for the CPU is output from the EXO port of IC4.
EEPROM Control Circuit
When the printer power is turned off, the following information is stored in EEPROM (IC4) which is nonvolatile memory. And, when the printer power is on, CPU (IC8) reads the information from EEPROM.
RTC Circuit
By adoption of the large-capacity capacitor (C9) for timer, the Power-off timer can be backed up for about one week after power-off.

2.4.2.5 Sensor Circuit
CPU (IC8) on the Main Board monitors the status of the printer by several sensors. However, unlike the previous product, ASF Unit on this printer does not have ASF Sensor. Instead of ASF Sensor, Change Lever and the Clutch mechanism is used to detect ASF home position. (As for the ASF home position detection, refer to “2.2.4
Paper Loading/Feeding Mechanism” (p.78).)
PE Sensor
This sensor is mounted at the right side center of the Printer Mechanism, and it detects the presence/absence of paper when the paper passes through the Paper Guide Rear. The PE Sensor is constructed of a transmissive photosensor and the PE Sensor Lever.
Paper Absent : Because the PE Sensor Lever does not interfere between
the photosensor terminals, a low signal is output to the CPU.
Paper Present : The PE Sensor Lever interferes between the photosensor
terminals, and a high signal is output to the CPU.
PG Sensor
This sensor is mounted at the left end lower section of the Printer Mechanism, and it detects the condition of PG (Platen Gap). The detection method used by the PG Sensor is mechanical contact points.
PG Normal : A low signal is output to the CPU.
PF Encoder Sensor
The sensor is composed of a transmissive photo sensors mounted to the loop scale of the PF Roller Unit left side and to the Main Board. Minimum resolution of 1/ 180 inch is provided, and output to the CPU is a high signal for the black slits on the loop scale and a low signal for the transparent slits on the loop scale. Control of the PF Motor is based on the output signal.
Thermistor (THM)
The thermistor is directly mounted on the Printhead driver board. It monitors the temperature around the Printhead and determines the proper head drive voltage to uniform the weight of the ink fired from the Printhead. This information is fed back to the CPU analog port. When the temperature rises, the head drive circuit lowers the drive voltage: When the temperature lowers, the head drive circuit rises the drive voltage.
Scanner HP Sensor
Mounted in the Scanner Unit, this sensor detects whether the CIS Unit is inside or outside the home position
Inside HP : A high signal output to the CPU.
Outside HP : A low signal is output to the CPU.
PG Large : A high signal is output to the CPU.
PW Sensor
The sensor is mounted to the bottom of the Carriage Unit. It detects the top and bottom, left and right edges of the paper being fed.
Paper absent : A low signal is output to the CPU.
Paper present : A high signal output to the CPU.
CR Encoder Sensor
The sensor is composed of a transmissive photosensor mounted to the back of the carriage and a linear scale mounted in the CR scan direction. Minimum resolution of 1/180 inch is provided, and output to the CPU is a high signal for the black slits on the linear scale and a low signal for transparent slits. Control of the CR Motor is based on the output signal. The home position of the Carriage Unit is detected by this sensor.

2.5 Banding Reduction System

Purpose
Banding Reduction System (BRS) is to speed up the print rate of the printer.
Principle
Conventional models use overlap printing (2-pass, 4-pass, etc.) in order to secure the image quality such as reducing banding, on the other hand, BRS equipped models calibrate dot generation rate per raster (ink implantation amount), perform 1-pass printing, and accomplish higher image quality (by reducing banding) and high-speed printing.
The following procedures is required to create the calibration data.
1. Print a test pattern with the printer.
2. Read the test pattern with the scanner.
3. The printer detects the banding by reading the test pattern density.
4. The printer generates the calibration data using the detected banding, and stores the data into the serial flash ROM (IC10) on the Main Board.
5. The calibration data is applied when printing.
There are three types of the calibration values to process the three sections: paper top section, normal paper feeding section, and paper bottom section., and those values are stored into the serial flash ROM (IC10) on the Main Board.
When printing, the host computer reads the calibration data, and the printer driver sends the calibrated print data to the printer main unit.
As for the models that are equipped with stand-alone print function, image processor of the printer calibrates the image.

P O I N T
As for Stylus Photo RX520/530 / Stylus CX7700/7800, BRS is applied only when printing with 720 dpi x 720 dpi print mode.
