Trimming Function
A trimming function is provided as a means of coordinating an image with the types of photo frames handled by the printer. This function is always activated so that the image fits within the photo frames.
This function is described briefly below.
The printed photo frame and an image to be printed are matched in length along one side and the image is resized along the perpendicular side to fit the frame on that side. Any part of the image that does not fit within the photo frame is trimmed away (not printed).

Rules on Numbering and Rotating Images
The numbers shown in the figure below indicate the photo frame numbers used for the print layout. Horizontally oriented images are printed as shown by the numbers. Vertically oriented images, which has more pixels vertically than horizontally, the vertical photo data is allocated instead, and the number shown in the figure below is then rotated 90 degrees 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.)

2.2 Printer Mechanism Operating Principle

2.2.1 Printhead

D4-CHIPS Turbo2 type printhead is employed, which produces variable sized dot and economy dot. The printhead configuration is as follows.
Nozzle configuration
Black: 90 nozzles x 1Color: 90 nozzles x 3 (cyan, magenta, yellow)
The nozzle layout as seen from behind the printhead is shown below.
Therefore, whenever the printhead, main board, or the printer mechanism must be replaced with a new one, the Head ID of the new printhead needs to be written into the EEPROM using the Adjustment Program. The printer generates appropriate PZT drive voltage based on the Head ID information.
Following explains the basic components of the Print Head.
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.
Nozzle Plate
The plate with nozzle holes on the printhead surface is called Nozzle Plate.
Filter
This filter is located beneath the ink supply needle which supply ink to the printhead from the ink cartridge. The filter is preventing dirt or dust from getting into the printhead. Any dirt or dust may interrupt normal ink flow or can cause nozzle clog adversely affecting the print quality.
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.
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 reduce unit-to-unit variation in ink droplet size, the printhead has its own Head ID (16-digits code for Stylus CX9300F/CX9400Fax/ DX9400F) which corrects PZT drive voltage for the printhead.

2.2.1.1 Printing Process
This section explains how the printhead of the on-demand inkjet printer fires ink drop from each of the nozzles.
1. When not firing ink drop When the printing signal is not output from the C696 main board, or the PZT drive voltage is not applied, the PZT does not change its shape. Therefore, the PZT does not push the ink cavity. The ink pressure inside the ink cavity is kept normal. (refer to Figure 2-6 (p.43) “When not firing ink drop”)
2. When firing ink drop When the print signal is output from C696 main board, the nozzle selector IC provided on the printhead transmits the data in 1-byte unit. Based on the drive 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 2-6 (p.43) “When firing ink drop”)
2.2.1.2 Printing Method
Stylus CX9300F/CX9400Fax/DX9400F offer printing with variable sized dot or printing with economy sized dot.
Variable dot mode
This mode is developed to improve the print quality on Epson designated paper. Three sizes of dot; micro, middle, and large are automatically selected and used for printing according to the print data, basically the same as conventional models. Superior quality can be achieved on the Epson paper.
Economy dot mode
Fixed larger sized dot is used for printing in economy mode, which enables fast printing with lower resolutions.

2.2.2 Carriage Mechanism

The carriage mechanism components include the carriage unit (including printhead, CR encoder sensor), CR motor, timing belt, and CR scale. The operating principles of the carriage mechanism are described below.
Figure 2-7. Carriage Mechanism
2.2.2.1 CR Motor Control
This printer employs closed-loop control, via the CR motor and an encoder, to control the carriage speed and position. Since the CR motor is DC motor, the printer controls the motor in the following methods in order to ensure stable print quality.
Heat control
The heat control over the CR motor is carried out based on the electrical characteristic of the motor such as torque constants, coil resistance and power supply voltages.
the CR mechanical load is in the initial state and saved into the EEPROM. According to the variations measured in the sequence, the voltage is corrected to make the drive current value constant reducing an individual difference.
CR measurement sequence
To set the appropriate drive voltage for the CR motor in accordance with variation of the CR motor mechanical load, the printer runs a CR measurement sequence and stores the measured data into the EEPROM at power-on or in an ink cartridge replacement sequence. A fatal error occurs if the printer detects that too much load is applied to the CR motor.
The above control and sequences enable to correct the drive voltage for the CR motor based on the mechanical load and the electrical characteristic of the motor. According to the corrected drive voltage, heating value of the motor is calculated. The printer automatically provides wait time per CR path during printing when the predetermined heating value is reached.
2.2.2.2 Carriage Home Position Detection
As the previous model, the carriage home position is detected by the CR motor drive electric current and carriage speed/position signals sent from the CR encoder. The detection sequence performed at power-on is described below.
1. Drives the CR motor to move the carriage until it contacts with the right frame, and then stops the CR motor. The carriage position is set as a position specified number of counts rightward from the home position.
2. Moves the carriage again to the carriage lock position to check the lock for proper operation.
3. The printer starts to monitor the carriage position through the CR encoder.
The printer causes a fatal error if too much load on the CR motor is detected due to obstruction on the carriage path or if no carriage position information is obtained due to CR encoder or CR scale failure.
CR motor drive dispersion measurement sequence
Variations in torque constant, coil resistance and power supply voltage of the motor are measured in a CR motor drive dispersion measurement sequence when

2.2.3 Paper Loading/Paper Feed Mechanism

The paper loading/feed mechanism are driven and controlled by the PF motor (DC motor) and the PF encoder. The PF motor drive force is transmitted to the LD roller and the PF roller via the gears in the mechanism. In the loading mechanism, paper is fed to the PF roller from the ASF unit, and the feed mechanism transports the paper during printing and ejects it.
The rotational direction of the PF motor switches between the loading and feed operations as shown in the table below.

• Releases the change lever from the clutch mechanism.
• Feeds a paper into the printer and transports it.
• Locks the clutch mechanism with the change lever.
The PE sensor detects the paper top and bottom edges during the loading and feeding operations. When the sensor could not detect the top edge of paper during the loading operation, the printer causes a paper out error. And when the sensor could not detect the bottom edge of paper during feeding operation, the printer causes a paper jam error. For more details on the errors, see

2.2.3.1 Paper Loading Mechanism (ASF Unit)
The paper loading mechanism loads paper from the ASF unit and feeds paper to the PF roller. The ASF unit includes the hopper, change lever, LD roller shaft, and clutch mechanism. The change lever and the clutch mechanism play an important role in the paper loading operation as described below.
1. ASF home position detection function The change lever and the clutch mechanism are used to detect the ASF home position. The counterclockwise rotation of the PF motor brings the change lever to engage with the clutch mechanism. The ASF home position is detected by the engagement of the change lever at the beginning of the paper loading operation. At this time, paper is not fed to the PF roller because the PF motor drive force is not yet transmitted to the LD roller shaft.
2. Paper loading function When the change lever is disengaged from the clutch mechanism by the counterclockwise rotation of the PF motor pinion gear, the printer changes to the paper loading state from the ASF home position detection state. The PF motor drive force is transmitted to the LD roller, and paper is fed from the ASF unit.
The rotation of the two cams on the LD roller feeds paper into the printer.
Larger cam: moves the hopperSmaller cam: moves the paper back lever
STEP1: ASF HOME POSITION
The counterclockwise rotation of the PF motor pinion gear (as seen from the left of the printer) causes the change lever to push down on the clutch lever, and the clutch lock tab is disengaged from the clutch gear as shown in
Figure 2-9. This cuts the PF motor
drive transmission to the LD roller shaft, and the shaft does not move at all. At the same time, the hopper is pushed down by the two cams on the LD roller shaft, and the paper back lever is set at the position to prevent paper from being fed. The “ASF home position” indicates all of the above statuses.
When the first sheet of paper has been fed, the second sheet is returned to the standby position by the hopper and the paper back lever, which are moved by the cams.
The following sections explain the paper loading sequence and operations of each components.

STEP2: RELEASING CLUTCH LEVER TO DRIVE LD ROLLER
When the PF motor pinion gear starts clockwise rotation (as seen from the left side), the change lever is moved toward the front of the printer to release the clutch lever. This causes the clutch to engage with the gear by being pulled by the extension spring. The clutch gear engages with the clutch lock tab and the PF motor drive force is now transmitted to the LD roller shaft.
STEP3: FEEDING PAPER FROM ASF
After the engagement of the clutch, the PF motor pinion gear starts counterclockwise rotation (as seen from the left side) and the drive force is transmitted to the LD roller shaft via the clutch lock tab and the clutch gear. When the LD roller starts to rotate, the paper back lever is returned to its standby position, and the hopper is released from the cams by being pushed by the spring. This causes paper to be caught between the hopper and the LD roller, and the further rotation of the LD roller feeds the paper into the printer.

STEP4: ENDING PAPER LOADING OPERATION
Continuous counterclockwise rotation of the LD roller (as seen from the left side) feeds paper to the PF roller. The LD roller rotation causes the hopper release cam and the paper back lever cam to push down the hopper and the paper back lever respectively. The paper back lever returns paper to the standby position to prevent multiple sheets of paper from being fed at once. When the LD roller and the clutch reach the ASF home position shown in “Step1” on the previous page, the clutch lever is locked again by the change lever. This causes the PF motor drive force not to be transmitted to the paper loading mechanism and to be transmitted only to the paper feeding mechanism.

2.2.3.2 Paper Feed Mechanism
The major components of the paper feed mechanism are the PF motor, PF roller, EJ (paper eject) roller, PE sensor, PF encoder sensor, and PF scale. The sheet of paper fed from the ASF unit is nipped between two rollers to be transported during printing and to be ejected.
1. The first two rollers used for feeding the paper are the PF roller and the paper guide roller mounted on the upper paper guide unit. The PF motor drive force is transmitted to the paper guide roller via the PF roller.
2. The next two rollers are the EJ roller and the star wheel roller mounted on the Star Wheel Holder Assy. The PF motor drive force is transmitted to the star wheel roller via the EJ roller.
The figure below shows how the PF motor pinion gear drive force is transmitted to the PF roller, EJ roller, paper guide roller and the star wheel roller.
When the PF motor pinion gear starts counterclockwise rotation (as seen from the left side), the sheet of paper fed from the ASF unit to the PF roller is transported and ejected from the printer by the PF roller/paper guide roller combination and the EJ roller/star wheel roller combination.

The counterclockwise rotation of the PF motor rotates the cam in counterclockwise direction to move the wiper downward, which is out-of position for cleaning.
Groove (2) of the cam is designed so that the cap slider protrusion cannot be set into the groove unless the wiper is moved downward. This prevents the slider protrusion from being engaged with the groove when the slider is moved downward without the wiper moved downward.

2.2.5 Ink Sequence

Initial ink charge
When the printer power is turned On first time after purchase, the initial ink charge is automatically carried out to fill the ink cavity in the printhead with ink. The initial ink charge flag in the EEPROM is cleared when the initial charge is completed successfully. Stylus CX9300F/CX9400Fax/DX9400F require about 120 seconds at maximum for the initial ink charge. If the power is turned Off during the process, the printer automatically runs a CL3 at the next power-on.
Manual Cleaning
Stylus CX9300F/CX9400Fax/DX9400F offer three types of manual head cleaning (CL1, CL2, and CL3) that can be run from the control panel. They delete air bubbles in ink, clear nozzle clogging, or to eject foreign materials.
CL1, CL2, and CL3 are performed in that order when the cumulative print time has not reached 9 minutes regardless of the number of print paths counted since the last CL. When 9 minutes has reached or exceeded, only CL1 is executed. In the case that any of the ink cartridges has almost run out or completely run out of ink, the LED flashes or light and the manual cleaning is disabled.
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 (time data) to the printer before printing. The 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, the printer stores the command in the EEPROM and compares it with the latest CL time which has been stored in the EEPROM. When the time difference exceeds the predetermined time period, the printer automatically runs the timer cleaning and stores the date and time of the cleaning in the EEPROM.
Flushing
The following two types of flushing is carried out automatically.
Pre-printing flushing
Reduces viscosity of ink inside the nozzles before starting printing.
Periodic flushing
Reduces viscosity of ink inside the nozzles during printing.

2.3 Scanner Mechanism

The major components of the scanner mechanism of Stylus CX9300F/CX9400Fax/ DX9400F are the scanner carriage unit and the scanner motor. However, the scan bed is divided into two parts including ADF reading section.

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, LED (light source), etc.
CIS Board
CIS Board contains the sensing elements that are placed across the entire width of an original. The sensing elements, which does not install a color filter, read an original through the Rod Lens Array by turning on red, green, and blue light­emitting diodes (LEDs) alternately. It is not the CIS Board but the Main Board that converts the analog light signal read by the Rod Lens Array into digital signal.
Rod Lens Array
A number of rod-shaped lenses, which are arranged on the sensing elements, are also placed across the entire width of an original. These lenses read the light reflected from the original that is produced by the light source (LEDs) and pass the information to the sensing elements. Compared to conventional CCD method, this optical system allows the focal length (distance between sensor and image scanned) to be shallow. Therefore, an original to be scanned should be brought close to the document glass. The optical system, in addition, is 1:1, (there is no optical reduction or enlargement) and this results in a scanner offering the solid performance in terms of accuracy.
Figure 2-20. Scanner Mechanism
LED
Three color LEDs (the three colors being red, green, and blue) illuminate the line to be scanned in the document. Unlike cold cathode fluorescent lamp used in CCD method, using LEDs requires no warm-up time and allows the CIS to be highly power efficient.

(refer to the figure below) The CIS board 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, 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.

2.4 ADF Mechanism Operating Principle

Stylus CX9300F/CX9400Fax/DX9400F have an ADF (Auto Document Feeder) which enables continuous scanning of the A4, Letter, and Legal size documents (plain paper).
This section explains the ADF mechanism and the document feed operating principles.

2.4.1 ADF Mechanism

The ADF mounted on Stylus CX9300F/CX9400Fax/DX9400F consists of the motors/ rollers and the sensors shown in
After document is loaded inside the ADF, the document is scanned by the stationary CIS at the ADF scan position and then ejected to the paper eject tray located under the document tray.

2.4.2 ADF Document Feed Mechanism

The following explains how the ADF feeds a document to be scanned.
FEED OPERATION (1)
1. When a scan job using the ADF is received with document loaded on the ADF detected by the ADF DOC sensor, the ADF motor starts to rotate in counterclockwise direction.
2. The counterclockwise rotation of the ADF motor lowers the document stopper and the ADF LD roller, and lowers the rotating ADF retard roller to make it contact with the document.
3. The ADF retard roller starts to feed document on the ADF, and feeds the top sheet of the document to the ADF LD roller. If multiple sheets of document are fed at once, the top sheet can be separated from the others by the elevated surface on the ADF frame near the document stopper.
FEED OPERATION (2)
4. After the top edge of the document reaches the lowered ADF LD roller, the document is transported by the ADF LD roller to the ADF PE sensor.
5. When the ADF PE sensor detects the top edge of the document, the ADF motor stops after forwarding the document by a predetermined number of steps. At this time, the top edge of the stationary document contacts with the ADF PF roller that is rotating in the reverse direction.

SCAN OPERATION
6. The ADF motor starts to rotate in clockwise direction and turns the ADF PF roller a predetermined number of steps to transport the document to the scanning start position. Then the document is scanned while being transported by the roller.
PAPER EJECT OPERATION
7. When the top edge of the document being scanned reaches the ADF EJ roller, the document transportation is made by both of the ADF PF roller and the ADF EJ roller. When the ADF PE sensor detects the rear edge of the document, the document is forwarded a predetermined number of steps to finish the scanning operation.
8. After the scanning is finished, the ADF EJ roller ejects the document to the paper eject tray.

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 Print Head 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 2-31 (p.62) for the printhead driver circuit block diagram.
Head driver circuit
The basic drive waveform is generated in the head 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 generating the head drive waveform is written in the memory in the head 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. The generated head drive waveform is transmitted to the 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.

2.5.2.3 Motor Driver Circuit
CR/PF MOTOR DRIVE CIRCUIT
The motor driver (IC12) on the main board drives CR/PF motors. The both motors are DC motor and are controlled by constant current PWM drive method.
Based on the output pulse (signal) from the CR encoder or PF encoder, the CPU (IC8) sets the appropriate drive voltage for the current operation and outputs the value as a special control signal to the motor driver (IC12). Then, based on the signal output from the CPU, the motor driver applies the corresponding motor drive voltage to the CR/PF motor.
When no data has been received for 5 minutes, the CPU sets the motor driver voltage to 0, and turn the motor driver Off to save power.
SCANNER MOTOR DRIVE CIRCUIT
The motor driver (IC12) on the main board drives the scanner motor. Using a PM type stepping motor as the scanner motor, constant current bi-polar drive is achieved. The motor driver IC (IC12) generates a motor drive waveform to control the motor based on signals sent from the CPU (IC8).
When no data has been received for 5 minutes, the CPU sets the motor driver voltage to 0, and turn the motor driver Off to save power.
ADF MOTOR DRIVE CIRCUIT
The motor driver (IC2) on the main board drives the ADF motor. Using a PM type stepping motor as the ADF motor, constant current bi-polar drive is achieved. The motor driver (IC2) generates a motor drive waveform to control the motor based on signals sent from the CPU (IC8).
When no data has been received for 3 minutes, the CPU sets the motor driver voltage to 0, and turn the motor driver Off to save power.

2.5.2.4 Complex Circuit
A complex circuit that incorporates the reset circuit, EEPROM, and RTC is employed.
RESET CIRCUIT
The RTC IC (IC10) monitors +3.3V and +5V on the logic line and +42V on the drive line. It outputs a reset signal to the CPU (IC8) in the cases described below.
+3.3V line reset circuit
IC10 monitors 3.3V line through VDD port, and transmits a reset signal to the CPU through FRST port if it detects an abnormal voltage.
5V line reset circuit
IC10 monitors 5V line through VDD2 port, and transmits a reset signal to the CPU through RST port if it detects an abnormal voltage.
+42V line reset circuit
IC10 monitors 42V line through VEX port, and transmits a reset signal to the CPU through EXO port if it detects an abnormal voltage.
EEPROM CONTROL CIRCUIT
EEPROM (RTC IC: IC10) is a nonvolatile memory that keeps data written to it even after the power-off. The CPU (IC8) reads data from the EEPROM (IC10) in the power­on sequence, and stores data into the EEPROM in the power-off sequence.
RTC CIRCUIT
By adoption of the large-capacity capacitor, the power-off timer can be backed up for about one week after power-off.
Figure 2-33. RTC Circuit Block Diagram
EEPROM stores the following information.
Ink counter
(Ink consumption in ink cartridges, Waste ink pad counter, etc.)
Mechanical settings
(Head ID, Bi-D adjusted settings, USB ID, etc.)
EEPROM is connected to the CPU with the four lines. Each of the lines are used for data transmission as shown below.

2.5.2.5 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
Paper Loading/Paper Feed Mechanism ” (p.45).
PE Sensor
This sensor is mounted at the right side center of the printer mechanism in order to detect the presence/absence of paper when the paper passes through the Upper Paper Guide.
Paper Absent: Light emitted from the light-emitting device of the sensor is
received by the light-receiving side of the sensor without interrupted by paper. A LOW signal is output to the CPU.
Paper Present: Light emitted from the light-emitting device of the sensor is
interrupted by paper. A HIGH signal is output to the CPU.
CR Encoder Sensor
The sensor consists of the two devices; a transmissive photosensor mounted on the back of the carriage and a linear scale attached along the carriage movement range. Fine black lines are printed on the linear scale in 1/180 inch of the minimum resolution. The photosensor outputs HIGH signal to the CPU each time it reads the black line, and outputs LOW signal each time it reads the non-printed area. The CPU controls the CR motor based on the signals. The carriage unit home position is also detected by the sensor.
PF Encoder Sensor
The sensor consists of the two devices; a transmissive photosensor mounted on the main board and a rotary scale attached at the left of the PF Roller Unit. Fine black lines are printed on the rotary scale in 1/180 inch of the minimum resolution. The photosensor outputs HIGH signal to the CPU each time it reads the black line, and outputs LOW signal each time it reads the non-printed area. The CPU controls the PF motor based on the signals.
Thermistor (THM)
The thermistor is directly mounted on the printhead drive board. It monitors the temperature around the printhead and determines a proper head drive voltage according to the detected temperature. This information is fed back to the CPU analog port. When the temperature rises, the head drive circuit lowers the drive voltage, and when the temperature lowers, the head drive circuit rises the drive voltage.
“ 2.2.3
ADF PE Sensor/ADF DOC Sensor
These sensors are mounted on the ADF Unit in order to detect document loaded on the ADF and position of the document while it is being scanned/transported. See “ 2.4 ADF Mechanism Operating Principle ” (p.56) for details.

2.6.2 FAX Image Storing Function

FAX IMAGE STORAGE
FAX images are coded (monochrome: MMR, color: JPEG) and stored in the image memory as much as possible. The stored FAX images are deleted when the power is turned off or a power failure occurs because the memory is a volatile memory.
When sending
When receiving
When receiving, the received data may be printed without being stored depending on the remaining space of the image memory.

All of the received file could be stored and the remaining memory space has not become less than threshold.
The remaining memory space fell below threshold while the second or later page was being stored.
The remaining memory space fell below threshold while the first page was being stored.
Note : If the image memory runs out during storing received images, the receiving is
When sending a monochrome image, the whole image is stored in the memory before establishing the connection. The image is deleted immediately after the sending operation is finished.
Basically, a received image is printed after the whole image is stored in the memory. The received image is not deleted after being printed for the purpose of reprinting, and stored as long as the memory space is available.

DELETING STORED FAX IMAGES
The received FAX images (data) stored in the memory are deleted when the remaining memory space becomes less than preset threshold. If multiple data exist, they are deleted from the oldest by a unit of page.

2.6.3 Communication Function

The fax supports only G3 FAX communication provided by ITU-T.
When sending
When receiving
• When sending monochrome images Performs a line connecting operation after accumulating images.
• When sending color images Performs a line connecting operation without storing images and sends color or monochrome images depending on the capacity of the destination fax machine.
• When performing normal receiving Prints after storing received images in the image memory. If the image memory is insufficient, the storing operation is canceled and printing is started.
• When performing polling receiving Connects to the line and receives color or monochrome images in accordance with the instructions of the destination fax machine.

2.6.4 Print Function

The received images, speed dialing lists, and various reports can be printed. They are stored in the memory within the limits of its capacity and can be reprinted from the newest one.

2.6.5 Save Setting Function

The speed dialing numbers, user’s fax number, and various settings are saved in a nonvolatile memory and maintained their values even when the power is turned off or
in case of power failure.

2.6.6 Data Recording Function

OPERATING PRINCIPLES FAX Function Operating Principle 67
Figure 2-35. Deleting Stored FAX Images (Sample)
This function records the data of such as communication logs or traces of the protocols to use the printing of reports or the like. For the details of communication logs etc., see
Chapter 3 "TROUBLESHOOTING" (p68).

2.6.7 External Telephone Function

This function enables the user to use the device like a TAM (telephone answering machine) connected to the external telephone terminal. While the Stylus CX9300F/CX9400Fax/DX9400F is connected to the telephone line, the external telephone terminal is cut off from the telephone line. Therefore, the device connected to the external telephone terminal has no effects on the quality of the sending/receiving images or the speed of communication.

3.1 Overview

This chapter describes how to solve problems.
Be careful to avoid electric shocks when checking the electrical
circuit boards (C696 MAIN and C696 PSE/PSB boards) while the power is turned on.
Touching an FET, transistor or heat sink with one hand while
touching a metal part of the mechanism with the other hand could result in an electric shock, so carefully avoid this.
After initial filling of ink has been repeated several times,
immediate moving or tilting of the printer could result in leaking of ink that has not been completely absorbed by the Waste Ink Pad. When initial filling of ink has been repeated several times, check the ink remaining in the tip of the Waste Ink Tube and the waste ink not absorbed by the Waste Ink Pad before moving the printer.
Disassembly and reassembly of parts is often required when
identifying the causes of problems. The parts should be disassembled and re-assembled correctly while referring to
“DISASSEMBLY/ASSEMBLY” (p.110) so that the operation
and status of each check item can be correctly verified.
Some individual part and units may require adjustment once
they are removed or replaced. If removing or replacing parts which have specific instructions for adjustment included in
“DISASSEMBLY/ASSEMBLY” (p.110), be sure to make these
adjustments after repairing the problem location.

3.1.1 Specified Tools

This printer does not require any specified tools for troubleshooting.

3.1.2 Preliminary Checks

Before starting troubleshooting, be sure to verify that the following conditions are all met:
The power supply voltage must be within the specification limits. (Measure the
voltage at the wall socket.)
The power code must be free from damage, short circuit or breakage, or miswiring
in the power code.
The printer must be grounded properly.
The printer should not be located in a place where it can be exposed to too high or
low temperature, too high or low humidity, or abrupt temperature change.
The printer should not be located near waterworks, near humidifiers, near heaters
or near flames, in a dusty atmosphere or in a place where the printer can be exposed to blast from an air conditioner.
The printer should not be located in a place where volatile or inflammable gases
are produced.
The printer should not be located in a place where it can be exposed to direct rays
of the sun.
The printer must be placed on a strong and steady level table (without an
inclination larger than five degrees).
Any vibrating equipment must not be placed on or under the printer.
The paper used must conform to the specification.
There is no error in handling of the printer.
Check the inside of the printer, and remove foreign matters if any, such as paper
clips, staples, bits of paper, paper dust or toner.
Clean the inside of the printer and the rubber rolls.

3.2.1 Motor and Sensor Troubleshooting

Motors
The resistance values for the CR motor and the PF motor are given below, however, the values cannot be used to check the motors status since they are DC motor and the resistance between the electric poles varies. Visually check the motors for abnormal operation and if it is hard to judge, replace the motor.
