PRINTER OPERATION The printer's operation procedures are explained below. You can operate the printer either by itself or with a computer. Both methods are explained below. 1.1 Printer Operation Procedure The printer's operation panel has a POWER button and a RESUME button to cancel printing operation or to cancel an error. With a computer, you can use the printer driver to adjust the print head's position and to change various settings. For details on using the printer driver with the computer, see page 3-22. RESUME button Cancels printing operation or an error. The cleaning and nozzle check pattern can be selected by the number of blinks of the indicator. Figure 2-1 Operation Panel 1.2 Status Indicator When you operate the printer by itself, you can find out the printer's operation status with the indicator. When an error occurs, the nature of the error can be determined by the number of times the indicator blinks. Normal Operation Indicator Display Green light Blinks green (Long/short) Light off Operation Status Power ON Power ON in progress, power OFF in progress, resume operation in progress, cleaning in progress, test printing in progress, front cover open, printing in progress Power OFF Error Indicator Display Blinks orange (Long/short) Green/orange (Toggle blinking) Operation Status The number of blinks differs depending on the error. See page 2-10 for details. The blinking method differs depending on the error. See page 2-11 for details. 2-1 Troubleshooting POWER button Turns the printer ON/OFF and cancels test printing. Part 2: Troubleshooting S600 1.3 Operating the Printer The printer has an offline operation mode that works when the printer is not connected to a computer and the power is on. To conduct the operations below, with the power turned on, hold down the RESUME button until the green indicator blinks for the specified number of times. Operation Cleaning operation Nozzle check pattern printing Roller cleaning operation --- Indicator Blink Count Once Twice 3 times Remarks --Load a sheet of B5 or larger paper. Load no paper or load A4 paper. 4 times Execute no operations. 1.3.1 Cleaning operation To start the cleaning operation, turn on the printer and hold down the RESUME button until the green indicator blinks once. Then let go of the button. Cleaning will then start. The black and color ink nozzles will be cleaned simultaneously by suction. This is the same as using the printer driver to clean all of the ink nozzles. 1.3.2 Printing the nozzle check pattern With the printer turned on, hold down the RESUME button until the green indicator blinks twice. The printer will then start printing the nozzle check pattern. If any printing flaws show up in this test printout, clean the BJ cartridge. Printing the nozzle check pattern requires B5 or larger paper. If the paper's width is narrower than the nozzle check pattern, the printer will print on the bare platen, dirtying the platen with ink. To stop printing of the test pattern midway, press the POWER button. Printing will stop and the paper will be ejected. The printer will remain on. If the problem persists even after cleaning the BJ cartridge three times, Perform Deep Cleaning of from the driver. If that still does not resolve the problem, replace the BJ cartridge. 2-2 Part 2: Troubleshooting S600 Troubleshooting Figure 2-2 Nozzle Check Pattern Printout 2-3 Part 2: Troubleshooting S600 1.3.3 Roller cleaning operation This is to remove the paper dust adhering to the auto sheet feeder's rollers. With the printer turned on, hold down the RESUME button until the green indicator blinks once. The cleaning of the rollers will then start. There are two cleaning methods: (1) Passing plain paper through Place a sheet of plain paper on the auto sheet feeder and execute roller cleaning. Do this three times. (2) Rotating the rollers without paper Execute roller cleaning without placing any paper on the auto sheet feeder. (The rollers will rotate ten times.) Do this three times. Do not execute the cleaning operation more times than necessary. Excessive cleaning will generate rubber dust which can affect the printer's operation. 2-4 Part 2: Troubleshooting S600 2. SERVICING 2.1 Before Troubleshooting Before troubleshooting, check the following and see if any of the applicable problems can be fixed. Problem The printer does not operate at all. No printing.

DISASSEMBLY AND REASSEMBLY 3.1 Cautions for Disassembly and Reassembly 3.1.1 Cautions for ink stains (Ink path/ink mist) During servicing, be careful not to touch the ink path and get ink stains on the printer, work table, and your hands and clothing. The ink path includes the BJ cartridge's ink tank supply inlet, the BJ cartridge's ink filter, the ink nozzles, head cap, wiper, and waste-ink absorber. Also, a printer that has seen long-time use or heavy-duty use may have ink mist soiling the platen, inside the front cover, and purge section. The rubbing of clothing can cause a build up of static electricity on the human body. Static electricity can destroy electrical components or alter the electrical characteristics of components. Be extra careful when handling the control board. 3.1.3 Deformation of spur tips Be careful not to deform the spur tips. The spur tips contact the paper after the printing. Since the spur tips' contact area is small, any ink adhering to the spur will be a minuscule amount that can be wiped off by the spur cleaner. It therefore will not dirty the paper. However, if the spur's tips are bent of out of shape, the contact area with the paper will be larger, and any ink adhering to the spur will be a larger amount that the spur cleaner might not be able to wipe off completely. The spur will then stain the paper with a dotted line. 2-13 Troubleshooting 3.1.2 Damage by static electricity Part 2: Troubleshooting S600 3.2 Exploded View Figure 2-3 Exploded View 2-14 Part 2: Troubleshooting S600 3.3 Disassembly and Reassembly Supplemental information and cautions for disassembling and reassembling the printer are stated below. As for the disassembly procedure, refer to the Parts Catalog. The illustrations in the Parts Catalog are numbered according to the order of disassembly. 3.3.1 Carriage lock release a b Purge Unit Figure 2-4 Carriage Lock Release 2-15 Troubleshooting Normally, when a cartridge is installed on the carriage and the power is turned off, the printer moves the carriage to the capping position to lock it. When the power is turned on, the carriage lock is normally released. However, if the printer does not operate properly, you can release the carriage lock manually in one of two ways: a) On the back of the printer, push down the purge unit's locking pin. b) On the front of the printer, rotate the gear as shown by the arrow in the illustration below so that the locking pin goes down. Part 2: Troubleshooting S600 3.3.2 Removing and installing tap screws The printer uses tap screws to fasten the printer unit and base. The removed tap screws will have residue from the mold in which the internal thread was made. Since the residue may crush the screw threads, clean off the residue from the tap screws before re-installing or use new tap screws. 3.3.3 Installing and removing the carriage encoder film The carriage encoder film is fixed in place and held taut by the torsion spring. When you install or remove the carriage encoder film, you have to stretch the torsion spring. Be careful not to pull the torsion spring too much in the direction of the arrow. Otherwise, you will not be able to properly install the carriage encoder film the next time. Therefore, when installing or removing the carriage encoder film, be very careful not to pull the torsion spring too much. Figure 2-5 Encoder Film 2-16 Part 2: Troubleshooting S600 3.3.4 Handling encoder film (1) Be careful not to get any grease on the encoder film (carriage encoder film and paper feed encoder film). If grease gets on the encoder film, the film's slits will not be read correctly, resulting in error. If grease gets on the film, use alcohol to wipe it off completely. (2) Do not fold or scratch the encoder film. If the film is folded and a white line is created or if a slit is scratched, replace the encoder film. 3.3.5 Removing and installing the control board C507 Capacitor Figure 2-6 Short-Circuiting the Capacitor 2-17 Troubleshooting Remove or install the control board with caution to prevent damage caused by short circuiting. When the printer is turned on and later turned off, the capacitor on the control board will still contain a charge for a while. In this condition, shorting the components on the control board will damage the components. Therefore as a preventive measure, follow step (1) or (2) below before removing or installing the control board. (1) After disconnecting the AC power, wait for 90 sec. (2) Use a resistance of about 100 to 500 ohms to short-circuit the C507 capacitor terminals for 1 sec. Part 2: Troubleshooting S600 3.3.6 Removal of red screws prohibited Since adjustment of the following red screws is very difficult in the field, they must not be loosened or removed. (a) The two paper spacing red screws (one on the right and left). (b) The two screws securing the paper feed motor. a b a Figure 2-7 Do not Remove the Red Screws 3.3.7 Installing the logic board cover If the logic board cover is installed incorrectly, the logic board and paper feed rollers will be obstructed and the ASF motor may go out of sync. Note that prong A is prone to engage incorrectly. Make sure that it fits in correctly. A Figure 2-8 Installing the Logic Board Cover 2-18 Part 2: Troubleshooting S600 3.3.8 Handling the purge unit Blade Cleaner Blade Figure 2-9 Handling the Purge Unit 2-19 Troubleshooting Note the following with regard to the purge unit: (1) Grease soiling the blade Due to the blade's height, the carriage guide shaft may touch it when the shaft is removed or installed. Grease may soil the blade as a result. You must not allow any grease or oily substance to adhere to the blade. (2) Replacing the blade cleaner When replacing the purge unit, also replace the blade cleaner at the same time. Since it is soiled by ink, the blade cleaner needs to be replaced. The spare part for this replacement includes both the purge unit and blade cleaner in one set. Part 2: Troubleshooting S600 3.3.9 Installing the control ROM cover When installing the ROM cover, make sure it goes beneath the guide rail, then secure it in place.

Use a flat brush to spread a thin coat of grease. When applying grease, be careful not to get any grease on the wiper and cap. Back of Guide Rail (Surface Sliding Against the Carriage) PG641: 25 mg Guide Shaft KG-107A: 225 mg Figure 2-11 Applying Grease 2-22 Part 2: Troubleshooting S600 3.4.3 Print head position adjustment Figure 2-12 Printing Position Adjustment Pattern 2-23 Troubleshooting The print head has two nozzle arrays for each color. Therefore, it requires the ink landing position adjustments described in (1) and (2) below in addition to the usual bi-directional adjustment described in (3). (1) Landing position adjustment between two same-color arrays • Black-Black array (A) • Cyan-Cyan array (B) • Magenta-Magenta array (C) (2) Landing position adjustment between two different-color arrays • Black-cyan/Magenta/Yellow (F) (3) Bi-directional landing spot adjustment (Same as with previous models) • Black bi-directional (D) • Color bi-directional (E) If the landing spot position is inaccurate, the pattern printing will show overlapping printing or gaps, resulting in black or white stripes. Therefore when doing the adjustment, use a pattern that has no stripes. Load one sheet of A4 paper in the auto sheet feeder, then use the printer driver to execute printing. Part 2: Troubleshooting S600 3.4.4 Print head seam stripe adjustment The print head seam stripe adjustment is done to determine the amount of thinning of the high-duty image portion (indicated by the arrows) comprising the seam (stripe) created between the vertical bi-directional passes. After the CMY printing by the first pass, CMY is printed again in the same way during the second pass. In the case of color printing, there are two feed methods for one pass: 64 and 128. Pattern G was made with 64 nozzles, and pattern H was made with 128 nozzles. When you execute printing with the printer driver, seven patterns with a changing degree of thinning (indicated by the arrows) will be printed vertically. Select the number of the pattern whose seam stripe is the least noticeable. This sets the optimum degree of thinning. Figure 2-13 Seam Stripe Adjustment Pattern 2-24 Part 2: Troubleshooting S600 3.4.5 Setting the EEPROM After replacing the control board or waste-ink absorber, reset the EEPROM and restore the printer settings. Then do a test printout to check the results. The procedure is described in 7.1 Service Mode Operations on page 2-29. Once the data in the EEPROM is reset, a test printout cannot be used to check the old data. Be sure to print the data before resetting. All the data, except the printer settings and USB serial number, will be reset. The various settings and waste-ink amount stored in the old EEPROM cannot be written to the new (replacement) EEPROM. The waste-ink full error is expected to occur only when the printer prints more than the number of sheets specified for its service life. However, how soon this error occurs varies depending on how many times the printer has been turned on/off, the number of times the BJ cartridge has been replaced (front cover open/closing), and the operating environment. 2-25 Troubleshooting (1) After control board replacement If the waste-ink absorption amount is over 7 percent (according to a visual check) at the time you replace the control board, also replace the waste-ink absorber. Otherwise, the waste ink amount cannot be counted accurately. Then reset the EEPROM and restore the printer settings. To check the waste-ink absorption amount, you can either check the service/ factory text printout from the old control board or visually check the waste-ink absorber's waste-ink absorption amount. Also, the new control board (EEPROM) does not have the correct data. The EEPROM must be reset. Otherwise, the waste-ink full error will not occur even when the waste-ink absorber's capacity is exceeded and ink could leak. (2) After waste-ink absorber replacement Clear the EEPROM's waste-ink counter. Part 2: Troubleshooting S600 4. OPERATION CHECK AFTER DISASSEMBLY AND REASSEMBLY 4.1 Check Procedure After disassembly and reassembly, follow the procedure below to check the printer's operation. 1) Check visually for any grease or foreign matter dirtying the internal parts. Make sure that the encoder film is clean. If there is any grease on the film, wipe it clean with alcohol. 2) Service/factory test printout with the printer alone Check for the following: Missing print in the nozzle check pattern, off-position horizontal lines in the horizontal line pattern, and white stripes in any irregular printing. If any of these occur, clean the print head and adjust the print head position. Then make another test printout. The procedure is described in 7.1 Service Mode Operations on page 2-29. Timing After control board replacement Items to Check The service/factory test printout must show the correct ROM version and product designation. It must also show the printed sheet count and that the total waste-ink amount has been cleared. The printer driver must be able to print the nozzle check pattern (to confirm that the computer is communicating with the printer). After absorber replacement The service/factory test printout must show that the total waste-ink amount has been cleared. Be sure to visually check the encoder film for any grease, foreign matter, etc. If there is any grease, etc., on the film, the printer may malfunction shortly after the repair is completed. 2-26 Part 2: Troubleshooting S600 5. TRANSPORTING THE PRINTER The procedure for transporting the printer after completing repairs is described below. 5.1 Procedure (1) Mount the BJ cartridge (print head) on the carriage. (2) Turn off the printer so that the carriage locks at the home position. 2-27 Troubleshooting If the BJ cartridge (print head) is not on the carriage, the ink may dry and harden. So even while transporting the printer, leave the BJ cartridge mounted on the carriage. Also, if the carriage is not locked at the home position, it will move while the printer is being transported. This may strain the paper feed encoder film. Part 2: Troubleshooting S600 6.

Therefore, after replacing the waste-ink absorber, be sure to reset the total waste-ink absorption amount. Also, after replacing the control board, be sure to reset the new control board's EEPROM and to also replace the waste-ink absorber. 7.5 Setting the Printer Settings in the EEPROM The control board used in the printer is also used in other printers. After replacing the control board, the printer settings for the respective printer must be set. After setting the printer settings, check it with the service/factory test printout. All the logic boards available as a replacement part contain printer settings for the S600. Therefore, if the logic board was replaced in Japan, be sure to set the correct printer settings. 2-32 Part 3 TECHNICAL REFERENCE Page 3- 1 3- 1 3- 2 3- 5 3- 7 3- 9 3 -10 3 -10 3 -11 3 -12 3 -12 3 -14 3 -17 3 -19 3 -22 3 -22 3 -22 3 -23 3 -24 3 -24 3 -25 1.

PRINTER CONTROL SECTION The printer control section converts the data created and input by the printer driver into printing data and printer operation signals and it also controls the driving of the print head and electrical mechanisms while referring to feedback from various sensors. 1.1 Printing Data and Control Signal Flow Host computer a Printer controller f c Receiving buffer d e Print buffer Logic section c BJ head DRAM b b g g MPU Control ROM Motor driver g : Print signal : Control signal Figure 3-1 Printing Signal Flow 3-1 Sensors Technical Reference The signal flow starting with the printer receiving the printing data and ending with the execution of printing is explained below. a) The printer driver in the computer creates a print file from the image data and compresses the print file. When the printer driver creates the print file, it obtains data concerning the amount of ink to be ejected from the print head. The printer driver refers to this ink ejection amount data. The printer driver can thereby create an optimum print file for the print head. b) The print data, including control signal output from the host computer, moves from the interface controlled by the printer controller (on the logic board) and is captured by the printer controller. The printer controller and DRAM are dedicated buses, and the print data is stored in the DRAM's receiving buffer (ring buffer). c) The print data stored in the receiving buffer is sent to the MPU. The firmware stored in the control ROM is divided into the control command and print data. The control command is processed in the MPU. d) Since the print data is compressed by the printer driver, it is controlled by the printer controller and uncompressed in the DRAM. e) When the printer controller receives a printing start request from the MPU, it obtains the print data in the DRAM print buffer. f) The printer controller converts the print data into serial data and transfers it as the printing signal to drive the print head. In the print head, the print data is converted from a serial signal into a printing data signal and the printing is executed. (See Printing Driving Method.) g) The MPU controls the printer controller, control ROM, and various motor drivers. While monitoring the status of the print head and printer, it also executes overall control of print driving. (See Sensors and Their Functions and Feedback.) Part 3: Technical Reference S600 1.2 Print Drive Method To print, the printer ejects ink from ink nozzles. To this end, 16-bit serial data is transferred once as a latch signal to each nozzle array (total of 8 arrays: black even/odd-number array, cyan, magenta, yellow/even/odd-number array). This operation is repetitive. The 16-bit serial data includes the following: Data (DATA0 ~ 9) that decides whether or not to heat 10 nozzles, data (BE0 ~ 4) that decides which nozzles to heat, and the dummy heater signal.

The nozzles to be heated are selected according to logical blocks of 16 nozzles divided from among the nozzle arrays. In the case of the black nozzles, they are divided into 10 blocks. The top-to-bottom sequence of the ten blocks will be BLE0 to BLE15. For example, in the case of BLE0, it will be as shown in the figure below. Ten nozzles will be selected in this case. b) The nozzles to be heated are selected individually. Among the 10 nozzles selected, the nozzles to be heated or not are selected. This is determined by DATA0 to DADA. c) Determining whether to heat a nozzle or not. The final decision to heat a nozzle or not is decided with the heat enable signal (HE1/HE2).

The vertical resolution applies to two nozzle arrays for each color. In the case of black, the two nozzle arrays have 300 dpi. Since their relative position to each other has been shifted by 600 dpi, both nozzle arrays together attain 600 dpi resolution. This enables 600 dpi resolution with single-pass printing. To enable a horizontal resolution of 2400 dpi, 3-dot printing is made possible in 600 dpi intervals. There are a total of eight patterns to enable or disable printing between the 600 dpi dots. Data 0 1 2 3 4 5 6 7 Printing 600 dpi interval 0 0 0 0 1 0 0 0 1 Print (1) /No printing (0) 0 1 0 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1 Figure 3-4 Printing Driving Method Since it is impossible to heat the nozzles successively in the horizontal direction at 2400 dpi intervals, the heating is broken into four passes. Thus, 2400 dpi printing requires four or more passes to be driven. However, the places that will be printed during a pass are determined by a random mask pattern. Therefore, it is not fixed. 3-4 Part 3: Technical Reference S600 1.3 Control During Printing The printer can produce high-quality printing with no smearing or irregular density with the cartridge, selected media, printing quality setting, printing data, etc., by altering the carriage operation, paper feed operation, etc. By shifting the printing timing with multiple passes during printing, one raster is printed with multiple nozzles. The amount of ink ejected by each nozzle is kept constant to reduce irregular printing density. Also, smearing is less likely to occur since the freshly printed ink is fixed before the next ink is printed. Depending on the paper, up to eight passes can be executed for printing. (For the number of passes allowable in each mode, see 7.1 Print Modes.) 1.3.1 2-dot Pair + Bi-directional printing 1.3.2 Seam stripe control Seam stripe control suppresses the stripes created at the seams between passes. It aims to produce a high-quality image with a single pass. For high-duty images where seam stripes are prone to occur between each pass, a dot-thinning process is executed. The degree of thinning to be implemented is determined when the user executes the print head position adjustment with the printer driver. 1.3.3 Rest between scans (Border detection control) To prevent color smearing and a whitish color cast along the border between a color ink and black ink caused by the inks' differing characteristics, printing can be executed with a rest inserted between scans. During the printer's internal print processing, the border between color and black inks is detected. When color ink is printed along a border with black ink, a wait is added for ink drying. The wait is set for each printing mode and each color. This reduces ink smearing. Since this operation reduces the throughput, the user is able to select a rest between scans (a special setting) for only plain paper or postcards (when smearing is most prone to occur). It is executed if the print data includes borders between black and color inks. 3-5 Technical Reference In the case of conventional bi-directional printing, when for example cyan and magenta are mixed to produce blue, cyan is printed during the first pass and magenta is printed during the second pass. The color printed on the first pass always comes out stronger than the color printed on the second pass. The subtle difference in color between the first and second passes creates irregular printing between scans. To resolve this problem, the printer uses two nozzle arrays for each color to print each pixel at 600 dpi. The image is created with 2 dots, and the sequence of printing each dot is controlled. In other words, the C2+M2 and M1+C1 portions to be printed during the first pass are mixed during a single scan. In the same way, the C1+M1 and M2+C2 portions to be printed during the second pass are mixed. The difference in color caused by the printing sequence still occurs, however, it is not recognized as irregular printing because it changes at 1200 dpi intervals. Part 3: Technical Reference S600 1.3.4 Smear control and rest between pages Both smear control and the rest between pages are for preventing smearing by the edge of the printed paper sliding against the preceding printed page. If pigment ink is used for high-duty printing, smear control can delay the printing operation right before the next sheet of paper is stacked on the printed sheet. Smear control is executed by the printer controller. As for the rest between pages, the user can set it with the printer driver so that printing stops temporarily after each page is printed, regardless of the printing data. The smear control and rest between pages are independent operations. If both the smear control delay time and rest time between pages are set, a longer time will take effect. 1.3.5 Automatic power ON/OFF The printer incorporates an automatic power ON/OFF feature. The printer turns on when it receives a printing signal from the computer, and it turns off automatically after a certain period of time when no printing signal is received. This feature can be set with the printer driver. With automatic power ON enabled, the printer turns on automatically when 3 or more bytes of data is received continuously. The interface will remain operational even during power OFF. (Set with the EEPROM.) With automatic power OFF enabled, the printer turns off when a set period of time elapses after the last printing data are sent by the computer. The printer does not turn off automatically in the following cases: An error has occurred, paper has been loaded into the manual feed slot, or when the front cover has been opened. 1.3.6 Print head protection from overheating If ink runs out and the printing operation continues, the bubble jet head will overheat. To prevent overheating, overheating protection control takes effect if the head temperature sensor inside the bubble jet head detects an excessively high temperature. 1.3.7 Power motor control Power motor control is for controlling the current to attain the following objectives: (1) Reduction of current consumption during printing The current is controlled so that the AC adapter's maximum output (momentary current) is not exceeded. By increasing the number of passes, current to heat the heater once is suppressed. (2) The head's average current consumption is suppressed to restrain the power source's temperature increase. Since the power source's temperature increases, it cannot be used while the average current is exceeded. 3-6 Part 3: Technical Reference S600 1.4 Detection Functions 1.4.1 Detection by sensors The following sensors detect the printer's condition. Cover Sensor (SW) Internal Temperature Sensor Paper Feed Encoder Purge Sensor Carriage Encoder ASF Sensor Figure 3-5 Location of Sensors 1.4.2 Paper-end sensor The photo interrupter-type, paper-end sensor detects the paper with the paper sensor arm's flag when the edge of the paper passes through the paper feed section. When there is no paper, the sensor is closed by the paper sensor arm. When paper is detected, the sensor is open and paper is thereby detected. 3-7 Technical Reference Paper-end Sensor Part 3: Technical Reference S600 1.4.3 Ink sensor (Same as for BJ F600) Consisting of an LED and photo sensor, the ink sensor uses optical means to detect whether there is ink in the ink tank. At the bottom of the ink tank is an indentation that works like a prism. When there is ink in the ink tank, the refractive index of the ink and the prism's resin material is about the same. Therefore, the reflected amount of light is small. When the ink is exhausted, the refractive index of the air and the prism's resin is very different, so all the light entering the sensor is reflected and the amount of reflected light is high. The ink sensor detects the difference in the reflected light amount to determine whether or not there is ink in the tank. The MPU detects the voltage that changes according to the change in the reflected light amount. The analog value that is input is converted to a digital value by an internal A/D converter. When the printer detects no ink in the ink tank, it indicates "ink low" on the status monitor for the respective ink tank. After the printer detects no ink in the ink tank, it starts to count the number of ejected dots corresponding to the amount of ink (about 20% of the ink amount) in the sponge and it starts to detect the no-ink error. This error is detected in the following cases: While the power is ON, when the front cover is closed, after the pumping operation, or after the set number of dots have been printed. If the front cover is opened during the ink amount measurement, the external light may prevent an accurate measurement. The presence of an ink tank will also not be detected. If there is no ink tank, there will be no reflected light and the printer will therefore assume that there is ink. Ink Tank Air Ink Refracted Light Reflected Light Incident Light Incident Light Photo Transistor Photo Transistor Ink Sensor Ink Present Prism Reflected Light Ink Sensor (Completely Reflected) No Ink Figure 3-6 Ink Sensor 1.4.4 Cover sensor The switch-type cover sensor detects whether the front cover is open or not. When the printer detects that the cover is open, it will move the carriage to the replacement position. 1.4.5 Pump sensor The switch-type pump sensor detects the tube pump rotation's initial position. From the pump's initial position as detected by the printer, the printer will start to control the pumping operation. 3-8 Part 3: Technical Reference S600 1.4.6 Internal temperature sensor The internal temperature sensor (TH201) on the control board detects the printer's internal temperature in order to control print head driving. When the printer's internal temperature changes, the thermistor's resistance also changes accordingly and the change in the resistance is detected by the MPU as a change in voltage. The analog value that is input is converted to a digital value by an internal A/D converter. 1.4.7 Head temperature sensor The head temperature sensor is in the BJ cartridge's print head. If the head temperature is abnormally high, the sensor detects the head temperature and the abnormal head temperature error is issued to stop printing operation. When the head temperature changes, the diode sensor changes accordingly and the voltage change is detected by the MPU. The analog value that is input is converted to a digital value by an internal A/D converter. 1.4.8 ASF sensor 1.4.9 Carriage encoder/paper feed encoder With the encoder, the light from the LED passes through the encoder film and enters the photo IC. It is converted into a digital electrical signal when the encoder rotates or when the carriage moves. With this feedback signal, the printer controls the driving of the DC motor. 1.5 Other Sensing Features Besides the sensors described above, the printer has the following detection features. 1.5.1 Waste-ink detection For print head maintenance, ink is ejected by the maintenance jet or purged by the recovery operation. The ejected or purged ink is absorbed by the waste-ink absorber. If the waste-ink absorber discharges ink because it contains more ink than it can absorb, the printer may leak ink. To prevent ink from leaking, the waste-ink absorber's full capacity is detected by estimation. The printer calculates the amount of waste ink produced by the maintenance jet and recovery operations by referring to the ink dot counter. While taking ink evaporation into account, if the estimated waste-ink amount exceeds 95% of the waste-ink absorber's capacity, the waste-ink warning is issued when the power is turned on. If the estimated waste-ink amount reaches 100% of capacity, the waste-ink full error occurs. 1.5.2 Print head detection The presence of the print head is detected with the AD value obtained from the head temperature sensor. If the temperature counted in reverse from the AD value is lower than the absolute 0 degree (an impossible value), the printer will assume that there is no print head. 3-9 Technical Reference The ASF sensor detects the ASF paper feed rollers' initial position. It detects the paper feed rollers' position during ASF initial positioning and paper feeding. Part 3: Technical Reference S600 2.

The +27 VDC's output is controlled according to the signal (DWCONT) output by the printer controller. The +27 VDC is used as LF, CR, ASF, and PG for the respective motor drive power source. The +19 VDC is the print head's heater driving power source. The +5 VDC is the logic system's power source. It is constantly supplied by the AC adapter. As a result, as long as AC power is being supplied, all the hardware except the sensors, driver IC, and BJ cartridge are in the active state. b) DC/DC converter The DC/DC converter on the control board converts the voltage into +5 VDC and +3.3 VDC and outputs both. The +5 VDC is used for the EEPROM and reset driving power source and the power voltage for the HVDD, VIF, and VSEN. The HVDD, VIF, and VSEN power voltage outputs are controlled by the printer controller. Also, the +5 VDC is used as the power source for the printer controller, MPU, DRAM, and control ROM. It is also used as a pull-up power source for various switches. By using +3.3 VDC as the power source, the power consumption during power off is less than when +5 VDC is used. Part 3: Technical Reference S600 3. PRINTER'S MECHANICAL PARTS 3.1 Overview of the Printer's Mechanical Parts The printer's mechanical parts consist of the BJ cartridge, carriage, purge section, and paper feed section. Each part is explained below. Carriage Paper Feed Section Carriage Figure 3-8 Printer's Mechanical Parts 3.1.1 Carriage The carriage holds one BJ cartridge in place. The carriage belt driven by the carriage motor (DC motor) moves the carriage horizontally back and forth across the paper. Regarding the carriage's position control, the initial position is detected when the carriage goes against the right wall which is the home position. After that, the carriage position is detected by reading the pulse from the encoder film. The paper spacing position is read from the carriage position when the carriage goes against the left wall. 3.1.2 Purge section The purge section, driven by a dedicated purge motor, consists of the wiper, pump, cap, and carriage lock. The wiper maintains the head face surface to ensure high-quality printing. The ink suction feature enables the ink to be readily ejected from the nozzles. When the BJ cartridge is not in use, the nozzles are protected by a cap, and the carriage is locked in place. The motor's running direction controls the ink suction operation or capping/wiping/ valve open/closing operation. 3-12 Part 3: Technical Reference S600 3.1.3 Paper feed section The paper feed section consists of the paper feed components, paper transport section, and paper discharge section. Paper feed Paper is fed automatically by the auto sheet feeder. The auto sheet feeder is driven by the paper feed motor. Paper of various sizes up to legal size can be stacked and fed automatically (the paper is transported to the paper transport section). Paper transport section The paper feed section, driven by the paper feed motor, keeps the sheet of paper flat and horizontal on the platen and rotates the feed roller to move the paper horizontally to and beneath the print head. Paper eject section After printing, paper is ejected onto the discharge tray by the eject rollers. After the sheet of paper leaves the paper feed rollers, the eject rollers take over to eject the paper. Technical Reference 3-13 Part 3: Technical Reference S600 3.2 Purge Section 3.2.1 Purge section functions In order to maintain good printing quality, the purge section maintains the BJ cartridge's nozzles. The purge section's functions consist of capping and cleaning. a) Capping The purge unit's cap is pressed against the print head's face to protect the nozzles from dust, etc., and to prevent the nozzles from drying out. To prevent the capping position from shifting, the carriage is locked in place at the same time. When the cap is open while the printer is on standby for printing and a certain period of time elapses (55 sec. with no paper or 20 min. with paper loaded), the print head will be capped automatically. You can also cap the print head by pressing the POWER button to turn off the printer. b) Cleaning Cleaning executes the following operations: Wiping: Paper residue and dried ink on the print head's face plate are wiped off. Suction: The ink is sucked out of the print head to refresh the nozzles with new ink. Maintenance jet: To eliminate any air bubbles in the head's nozzles and to remove waste particles near the nozzle openings, ink is ejected from the nozzles onto the cap and maintenance jet receptacle. Cleaning is performed at the times below to ensure that the head produces highquality printing. 3-14 Part 3: Technical Reference S600 3.2.2 Purge section components Cleaner Wiper Cap Purge Motor a) Purge driving motor The purge motor drives the wiper, carriage lock, and pump. It is a constant-voltage motor operating with a 1-2 phase drive. b) Wiper The wiper consists of a wiper and wiper cleaner. The wiping operation is executed while the carriage is fixed at the purge section. It wipes the print head's nozzle array in a vertical motion. c) Cap The rubber cap protects the print head (capping operation) and sucks out (pumping operation) the ink in the cap. When the carriage moves to the capping position, the cap is pressed against the print head's face plate. There is a different cap for the black and color print heads. An ink tube connects the rubber cap to the pump and air valve. 3-15 Technical Reference Figure 3-9 Purge Section Components Part 3: Technical Reference S600 Rotation Direction for Wire/Capping Rotation Direction for Ink Suction To Waste-Ink Absorber Valve Open Valve Closed Rotating Roller (inside) Black Ink Tube Color Ink Tube Figure 3-10 Pump Operation d) Pump This is a tube pump system consisting of two ink tubes (one for black and one for color) pressurized by a rotating roller. A negative pressure is thereby created to suck the ink. Inside, there is a valve dedicated to black ink and one dedicated to color ink. When the valves close or open separately or simultaneously, only the black ink (color valve open) or color ink (black valve open) can be sucked or both inks can be sucked (black and color valves closed). The amount of ink sucked can be high, medium, or low depending on how much the roller rotates. The pumping operation is executed with the rotation of the roller after the carriage is released from the capping position and both valves are opened. The degree of rotation of the pump's roller and the timing of the rotation are controlled by the step count in accordance with the initial position detected by the pump sensor. The two tubes are placed right before the waste-ink absorber. By mixing pigment ink and dye ink, ink hardening is prevented. 3-16 Part 3: Technical Reference S600 3.3 Paper Feed Section 3.3.1 Paper feed components The paper feed components include an ASF incorporating a friction separation system which uses a separation pad. Compared to previous ASF systems, it has a very strong paper feed force. It consists of the following parts: Paper feed roller and separation pad, pressure roller and return corner, pressure plate, motor, and sensor. Nip Paper feed roller (Transports the paper) Chin Pressure roller (Applies pressure on the paper on the separation pad to prevent transporting more than 1 sheet) Pressure plate (Puts the next sheet in position for the paper feed roller) Figure 3-11 Paper Feeding The motor is a constant-current stepping motor. It drives the paper feed roller with 12-phase driving. There is a sensor on the paper feed roller to detect the paper feed roller's initial position. The pressure roller and return corner prevent the paper that could not be completely separated by the separation pad from proceeding to the paper transport section. The pressure roller presses down the sheet of paper that is on the separation pad. It prevents multiple sheets from being transported. The paper therefore has a back tension (counteracting force against the feed roller's pulling force on the paper). Also, the return corner is for returning the paper remaining on the separation pad. The timing for returning the paper changes depending on the paper type and length selected with the printer driver. 3-17 Technical Reference Return pawl (Returns the paper remaining on the separation pad) Separation pad (Separates the paper) Part 3: Technical Reference S600 3.3.2 Friction separation system The friction separation system's paper separation method is explained below. 1. When the paper feed roller turns, the top sheet of the paper stack is taken to the nip where the pressure roller contacts the paper feed roller. 2. When the top edge of the paper reaches the nip, the paper pushes down the pad by the amount of the paper's thickness. At this point, since the frictional force between the paper and separation pad is less than the frictional force between the paper and paper feed roller, the paper feed roller further transports the paper into the printer. 3. At this time, the next sheet of paper stops at the chin. 4. If the next sheet of paper could not be stopped at the chin in step 3, it will be stopped on the separation pad because the frictional force between the paper sheets is less than the frictional force between the paper and separation pad. Only the top sheet is therefore sent into the printer. 3.3.3 Paper transport section At the printing section, an unchanging gap between the paper and print head is maintained while the paper is pressed against the platen as it goes between the pressure roller and paper feed roller and between the spur and eject roller. For paper transport control during printing, a metallic, high-precision paper feed roller having a coat of ceramic paint and an optical encoder film affixed on it is used. The paper feed roller is driven by a DC motor via a belt. The paper transport is controlled according to the signal read from the encoder film. The paper is transported in 1/1440-inch increments. 3.3.4 Paper discharge section While the sharp-tipped spur presses down the printed side of the paper (without marking the paper) against the eject rollers, the eject rollers discharge the printed paper. The paper discharge section consists of the eject rollers and spur. The sheet of paper brought to the printing starting position is printed on as it goes around the platen. The paper is transported by the paper feed rollers and pinch roller. When printing is completed, the paper is ejected by the eject rollers and spur. A Spring tabs on the left and right keep the discharged sheets stacked properly. 3-18 Part 3: Technical Reference S600 4. LOGIC BOARD COMPONENTS Control ROM Printer Controller DRAM Stepping Motor Driver IC MPU EEPROM Figure 3-12 Control Board a) Printer controller (IC101) The printer controller has the following eight functions. It operates with a 48 MHz external clock (not synchronized with the CPU). 1. I/F control The data is transferred with a serial (USB 1.1 standard) or parallel (IEEE 1274 standard) transmission. Parallel transmissions operate in the compatible, nibble, and ECP modes. 2. Receiving buffer control The ring buffer-type receiving buffer and the straight-type transmission buffer are controlled. 3. System management enabled With the built-in timer, any clock stoppage or suction time is counted. Also the status of the port in the printer controller is sampled. 4. Data decompression The data compressed by the printer driver is restored as print data. In addition, during printing in the HS mode, 300 dpi data is expanded by 2× vertically and horizontally to 600 dpi. The CMY 2-bit data is also distributed to the even/odd buffers for each even/odd array on the print head. 5. Data processing A dot count is executed for power monitoring and smear processing. Also, dot thinning for seam stripe processing is based on the dot count and color tone. 6. Printing control The data received is rearranged in the raster direction. Also, data is processed so that the print head's heaters are heated in the suitable sequence. 3-19 Technical Reference DC Motor Driver IC Part 3: Technical Reference S600 7. Print head control Serial print data is sent to the print head. The transfer clock is 6 MHz. Since data latch occurs at the clock's start-up and shutdown, the data transfer speed is faster. Also, the print head heater's heating is executed with a single pulse or double pulse. In the case of a double pulse, the first pulse is a press pulse. The pulse following it becomes the main pulse. The print head's temperature is estimated with the dot count. Based on the estimated temperature, suitable heating is executed with the voltage value. 8. Motor control The encoder signals input from the two DC motors are processed, and a signal for the 1-2-phase driving of the auto sheet feeder motor is generated. b) MPU (IC203) The MPU contains a 32-bit CPU, 16 KB work RAM, 21-bit address bus port, 16-bit data bus port, interrupt controller, A/D converter, I/O port, and other built-in components. With the chip select signal, the MPU selects the control ROM, printer controller, and DRAM. Built-in CPU The 32-bit CPU operates in synchronization with a 48 MHz external clock input. Address bus/Data bus This operates in synchronization with a 20 MHz external clock input. An external RAM (16 Mbit) is accessed via the 16-bit data bus. Interrupt controller The MPU receives external interrupts from the POWER button's ON/OFF and I/F. A/D converter The following analog signals are detected after they pass through the built-in A/D converter. Resume key input EEPROM data I/O EEPROM chip select output Door sensor input CSB power input Sensor (purge, paper end, sheet feeder) inputs LED (ERROR/POWER) outputs I/F (Centronics/CSB) pull-up control I/O Print head power control (ON/OFF) (VDD/VH) Ink sensor power control (ON/OFF) Purge motor control (4 ports, A/B/A/B phase) I/O port The I/O port executes the following control operations. c) DRAM (IC103) The 16 Mbit DRAM is controlled by the printer controller and used as a receiving buffer, download buffer, print buffer, and working area. 3-20 Part 3: Technical Reference S600 d) DC motor driver (IC504/505) The motor driver IC is for driving the DC motor (paper feed motor and carriage motor). This driver is a PWM (pulse-width modulation) IC that changes the current's pulse width to control the output. It thereby controls the motor. The pulse-width control is defined by the serial data (10 bit) from the printer controller. e) EEPROM (IC402) The 2 Kbit EEPROM controlled by the printer controller records the waste-ink absorption amount, page count, and BJ cartridge removal/installation count. The printer reads the EEPROM contents when AC power is supplied and records the data when the power is turned off. f) Control ROM (IC102) The 8-bit control ROM is written with a printer control program. 3-21 Technical Reference g) Stepping motor driver IC (IC503) This is a driver IC for constant-current driving of the ASF motor. The driving method is 1-2-phase driving. Part 3: Technical Reference S600 5. OPERATION WITH A COMPUTER For printer operation with a computer, printing with the printer driver's "Basic Setting Sheet" and setting the "Utility Sheet" are explained below. 5.1 Printing Operation with the Basic Settings Sheet To enable the user to print easily, the printer driver's ease of use has been improved. The Basic Settings Sheet enables the user to set the paper type, paper feed method, and printing quality. Also, the "Print Advisor" is a new feature. When the user does not know which paper is suitable for printing, the Print Advisor gives on-screen instructions so that the optimum settings are selected automatically. 5.2 Using the Utility Sheet This enables the usual operations such as cleaning, print head refreshing, print head position adjustment, nozzle check pattern printing, power OFF, automatic power setting, and special settings (economy cleaning, smear control, ECP, etc.) for status monitor start-up. When printing is executed for a large amount of data and the ECP mode check is off, the printing speed decreases. Figure 3-13 Basic Settings Sheet (Sample) 3-22 Part 3: Technical Reference S600 6. INK SUCTION AMOUNT IN THE CLEANING MODE The printer has five cleaning modes (A to G). Cleaning is executed for maximum effectiveness and efficiency. The cleaning operation is selected depending on the respective condition. The ink suction operation differs depending on the condition at three occasions: Operation by the user, cover open/closing, and before printing starts. • Operation by the user: Manual ink suction (Including printer driver operation) • Cover open/closing: Cleaning at printer arrival • Before printing starts: Other than manual suction Mode Cleaning A Bk+Cl Bk Bk Cl Cl Cleaning D All colors Bk+Cl Cleaning E Cleaning F Cleaning G Bk Cl All colors All colors All colors Bk Cl Bk+Cl Bk+Cl Bk+Cl *1 If the preconditions overlap, the stronger suction will take priority. Cleaning A < Cleaning D < Cleaning E < Cleaning F < Cleaning G *2 In the case of the boxed preconditions, the suction starts right after the precondition is executed. For other preconditions, suction is executed right before the printing starts or during printing. *3 Ink tank replacement is detected when the ink tank's status changes from H to L. *4 Printing of EEPROM contents, etc., with the printer alone. *5 Purging operations will be performed after 24 hours only the first 5 times, after which purging will occur at 60 to 336 hours intervals. When checking the functions of the purge unit, measure the suction amount for a manual suction. 3-23 Technical Reference All colors Suction Precondition* Amount (g) 0.15+0.36 Dot count suction, Manual suction (All colors) *2, timer suction (Time not set)*4 0.15 Dot count suction, Manual suction (Bk) , timer suction (60*5 ~ 336 h) 0.36 Dot count suction, Manual suction (Cl) , timer suction (120 ~ 336 h) 0.3+0.72 Tank replacement*3 after soft power ON (All colors) 0.3 Tank replacement*3 after soft power ON (Bk) 0.72 Tank replacement*3 after soft power ON (Cl) 0.45+0.72 Long timer suction (336 h ~) 0.45+1.08 When print head is replaced, at printer arrival 1.5+1.08 Head refreshing Part 3: Technical Reference S600 7.

PRINT HEAD The two nozzle arrays for each CMY color are divided symmetrically left and right along the M line. This makes it completely compatible with bi-directional printing. Also, the relative position of the two nozzles is shifted by 600 dpi for black and by 1200 dpi for color. Thus, the two nozzles together on a single pass produce 600 dpi resolution for black and 1200 dpi resolution for color. There is a heater near the nozzle openings and small ink drops are ejected with a strong force.
