13 CHAPTER II THEORY OF OPERATION 2.1 OUTLINE OF MECHANISMS Print Mechanism Structure of Thermal Head This machine uses thermal transfer printing. The thermal print head has a heat generator consisting of 384 heating elements that are vertically aligned as shown in Fig Each heating element is 0.08 mm wide by mm height ( mm per pitch). Fig Heat Generator of the Thermal Head Printing Process In printing process, the cylindrical rubber platen is pressing the tape(*) and ink ribbon(**) against the thermal print head. The heat generator divided into 384 elements on the thermal print head is impressed selectively in this process. Principle of printing varies depending on whether the heat sensitive tape cassette is used or not. * Laminate tape when using laminated tape cassettes. Non-laminated tape when using non-laminated tape cassettes. Instant lettering tape when using instant lettering tape cassettes. Iron-on transfer tape when using iron-on transfer tape cassettes. Cloth tape when using cloth tape cassettes. Thermal tape when using AV (Avery) labels cassettes. ** When using AV labels cassettes or stamp tape cassettes, no ink ribbon is sandwiched. [For tape cassettes except stamp tape cassettes and AV labels cassettes] If the selected heating element(s) generates heat, the ink on the sandwiched ribbon will be melted and transferred to the tape, producing a dot(s) on the tape. The ink ribbon and the tape are advanced and then the next heating cycle is repeated, thus forming a character on the tape. [For AV labels cassettes] If the selected heating element(s) generates heat, the thermal tape develops itself to produce a dot on the tape. The tape is advanced and the next heating cycle is repeated, thus forming a character on the tape. II-1

14 [For stamp tape cassettes] If the selected heating element(s) generates heat, the porous-stamp tape will be melted so that a pore (pores) will be formed in the tape. The tape is advanced and the next heating cycle is repeated, thus forming a character of pores on the tape. The printed stamp tape can be used as the face of a stamp. When the stamp is pressed against the ink-pad, it will absorb ink through the pores. For laminated tape cassettes, instant lettering tape cassettes, and iron-on transfer tape cassettes, the CPU processes the print data to generate a mirror image so that the printed character can be seen normally when viewed from the other side of the printed face of the tape. Character Formation The tape feed motor (stepping motor) feeds the tape and the ink ribbon (or only the tape when mounting the heat sensitive tape cassette) by mm per 3.5 ms, while the thermal head generates heat once. (In the high-speed printing, the tape is fed by mm per 1.76 ms, In the high-resolution printing, the tape is fed by mm per 1.76 ms). Feed amount of one step ( mm) is shorter than the width of heating element (0.08 mm), so that the continuous heat generation cycle will offer the dot printing having no gap between the adjacent heating cycles. This forms a character and a figure having no gap between adjacent printed dots. II-2

15 2.1.2 Roller Holder ASSY Setting & Retracting Mechanism This mechanism consists of the release gear train, roller release rod, and roller holder/head ASSY. The roller holder ASSY incorporates the platen holder and the sub roller holder. These holders support the platen and the tape feed sub roller so that they can move perpendicularly to the thermal head and the tape feed roller respectively to apply the platen with a certain pressure against the thermal head to ensure the tape feeding even if the tape thickness changes. As the release motor rotates, the rotation is transmitted to the release gear and the motion of the cam of it moves the roller release rod to the direction marked by the arrow. This rotates the roller holder ASSY around the rod fixed to the thermal head ASSY so that the roller holder ASSY is pressed against the thermal head. The release motor stops when the CPU receives the signal from the roller holder sensor generated by the pressure from the roller release rod. The platen presses the tape and the ink ribbon (or only the tape when mounting the heat sensitive tape cassette or the AV labels) against the thermal head under a uniform load by the platen spring. On the other side in this state, the platen gear engages with the platen idle gear. Also, the tape feed sub roller presses the adhesive base tape and the tape (or only the tape when mounting the non-laminated tape cassette) against the tape feed roller built in the tape under the uniform load applied by the sub roller spring. In this state, the tape feed sub roller engages with the tape feed gear. As the release motor rotates, the drive power is transmitted via the release gear to the roller release rod, which moves to the counter direction marked by the arrow. This motion releases the roller holder from the thermal head and provides the appropriate gap between the platen and the thermal head to allow the replacement of tape cassette. The release motor rotates and stops according to the potion of the roller release rod, which is detected with the roller holder sensor. The roller holder ASSY is set when printing. Note that the roller holder is released automatically under the following states. - The AC power is supplied with the machine. - The cassette cover is opened. - The power supply to the machine is cut by pressing the power supply button. - The machine is let stand for a certain time (10 minutes) after printing.

17 2.1.3 Tape & Ribbon Feed Mechanism This mechanism consists of the tape feed motor, the gear train, and the roller holder ASSY. Tape Feeding The platen becomes the state pressing the tape and the ink ribbon (only the tape when mounting the heat sensitive tape cassette) against the thermal head when printing, as described in Subsection Also, the tape feed sub roller in the roller holder ASSY becomes the state pressing the tape (the sandwiched laminated tape and the adhesive base tape when using a laminated tape cassette) against the tape feed roller built in the tape cassette. As the tape feed motor (stepping motor) rotates, the rotation is transmitted via the gear train to the tape feed gear and the platen idle gear so that the platen idle gear, the tape feed roller and the tape feed sub roller rotate at the same rotation speed. Accordingly, the sandwiched tape and the ink ribbon will be advanced at the same speed. (When a laminated tape cassette is mounted, the sandwiched laminated tape, the adhesive base tape, and the ink ribbon will be advanced at the same speed.) The feeding amount of the tape feed sub roller is slightly greater than that of the platen roller. Adhesive base tape Tape feed roller Transparent laminated tape Platen idle gear Tape feed sub roller Platen roller Thermal head ASSY Roller holder ASSY Main frame Tape feed gear Sub roller gear Tape feed motor Platen idle gear Platen gear Fig Tape Feed Mechanism II-5

18 Adhesive Base Tape Feeding (only for laminated tape cassettes) A laminated tape cassette contains both a transparent laminated tape roll and a separate adhesive base tape roll. When a transparent laminated tape and an adhesive base tape pass through the contact point (between the tape feed roller and the tape feed sub roller), they are then bonded together into a single printed tape. The ink printed on the transparent laminated tape is, therefore, sealed up with the adhesive base tape. Ink Ribbon Feeding (The heat sensitive tape cassette is not applied.) As the tape feed roller rotates, the ribbon drive cam located at the middle of the gear train rotates counterclockwise. When fitted on the ribbon drive cam, the ribbon take-up roll in the tape cassette also rotates to take up the ink ribbon. To apply proper tension to the ink ribbon between the platen roller and the ribbon drive cam, the feed speed of the ribbon drive cam is slightly greater than that of the tape feed roller. The differential between the feed speed at the platen roller and the ribbon drive cam gives a certain tension to the ink ribbon by the clutch spring that allows the cam to slip. This mechanism allows the ink ribbon to keep proper tension, which enables the ribbon take-up roll to clearly separate from the tape at the sterilized angle after printing.

19 2.1.4 Tape Automatic Full Cutter Mechanism The tape automatic full cutter mechanism consists of the fixed blade and the movable blade, which is driven by the full cutter motor. The full cutter motor (DC motor) rotates counterclockwise responding to the signal sent from the CPU when the tape is fed after printing, which transmits the rotation to the cutter helical gear. The cutter helical gear rotates counterclockwise, which turns the movable blade around the shaft B to the direction of the arrow shown in the figure below, along with the motion of the boss A (inserted into the long hole of the movable blade) of the gear. This way, the cutter cuts the printed tape advanced through between the fixed blade and the movable blade with the same mechanism as scissors. The CPU keeps ON status of the full cutter motor after the tape cutting motion, and then stops the full cutter motor at the moment receiving the signal from the cutter sensor switch, which is generated when the C part of the cutter helical gear presses the full cutter sensor mounted on the half frame when the movable blade returns to the home position. Fixed blade B Movable blade Full cutter motor ASSY C Full cutter sensor A Cutter helical gear Cutter helical gear Fig Tape Automatic Full Cutter Mechanism II-7

20 2.1.5 Tape Automatic Half Cutter Mechanism The tape automatic half cutter mechanism consists of the fixed plate and the half cutter holder (the cutter blade is attached) driven by the half cutter motor. This mechanism is applied only to the laminated tape. After tape printing and feeding, the CPU directs to rotate the half cutter motor (DC motor) counterclockwise, and the drive power is transmitted to the half rock gear via the clutch gear and three idle gears. Then, the half rock gear rotates counterclockwise, and the groove D of the gear moves the half cutter holder around the shaft E because the boss of the half cutter holder is engaged with that groove. The fixed plate has the step equivalent to the thickness of the separator of the laminated tape, against which the half cut holder (the cutter blade is attached) presses the laminated tape for half cutting. * Half cutting means the cutting motion to cut only the tape leaving the separator un-cut. Then, the CPU directs to rotate the half cutter motor in reverse, by which the half cutter holder is returned to the home position, the half cutter sensor on the half frame is pressed by the F part of half rock gear and the motor is stopped at the moment when the CPU receives the signal from the sensor. Fixed plate E Half cutter motor ASSY F D Half cutter holder Half rock gear Half cutter sensor Tape Separator Cut line Fig Tape Automatic Half Cutter Mechanism II-8

21 2.1.6 Forcible Tape Ejection Mechanism The forcible tape ejection mechanism consists of the eject rubber roller unit and the eject roller unit driven under synchronizing with the cutter mechanism. After tape printing and feeding, the cutter helical gear rotates counterclockwise when the cutter mechanism starts to work (as described in Subsection 2.1.4) and the boss A on the gear (engaged with the cam G of the eject roller unit) moves the eject roller unit around the shaft H. After the cutter cuts the printed tape, the eject roller presses the tape against the eject rubber roller. This motion of the eject roller unit is driven by the cam G. After the cutter cuts the tape, the full cutter motor ASSY stops its rotation for a time. The eject motor starts to rotate immediately after the cutter motor stops, which rotates the eject rubber roller via the gear train to eject the nipped tape. Rotation of the eject rubber roller is stopped after the given time and the full cutter motor ASSY starts to rotate again. The rotation of the cutter helical gear opens the eject roller unit to the direction J by the force of the return spring. Then the eject roller unit stops at the stopper L of the eject rubber roller unit.

23 2.1.9 AV Label Print Start Position Detector Mechanism (for U.S.A. only) This mechanism makes it possible to print at the proper position on Avery (AV) labels half-cut in a 24-mm-width AV labels tape. As shown below, it uses a reflection photosensor named AV print position sensor (AV sensor PCB ASSY). When a black detection mark (lower mark) printed on the back of an AV labels tape comes to the AV print position sensor, the sensor receives no reflected light, signaling the print start position. (1) Pressing the Print key will start tape feeding. (2) When a lower black detection mark on the back of an AV labels tape comes to the AV print position sensor, printing will start. (3) When the printed label exits from the tape cutter position, tape feeding will stop. The AV labels tape will be automatically cut off.

27 2.3.1 Logic Components [ 1 ] CPU The CPU (U6), 32-bit microcomputer of Renesas Technology, controls and manages entire system. This CPU includes no internal ROM. The internal RAM of M30823MH is 24 Kbytes and the internal RAM of M30800 is 8 Kbytes. [ 2 ] RAM (SRAM) Two 128 Kbytes SRAMs (U9 and U10) are used. These RAMs are used for data buffer. [ 3 ] EEPROM Two 4Kbit EEPROMs (U1 and U4) are used. This memory writes and stores the mechanical information such as baud rate information, Vendor ID code and product ID code. When replacing the main PCB, the data printed on the EEPROM body on the main PCB such as serial number and mechanical alignment data must be stored. Use the provided dedicated software to store the data connecting the PC to PT-9500PC with the serial IF cable as shown in Fig For more information, refer to Appendix 1. Test Software Operation.

28 2.3.2 Solder Points Fig shows the solder point circuit. One of solder points from L to S is soldered according to the resistance level of the thermal head. When the solder point is changed, verify with a multi meter whether solder on the unsolder point is removed properly. Caution: Be sure to use the lead-free solder. Fig Solder Point Circuit Cassette Sensor & AV Cassette Sensor Circuit The sensor circuit consists of a 6-switch cassette sensor (CSNS0 through CSNS5) and AV cassette sensor (AVSW). Loading a tape cassette turns on some of those five switches on the cassette sensor while keeping other switches off depending upon the ID encoding holes provided in the tape cassette currently loaded. If an encoding ID hole is closed, the corresponding sensor switch goes on. The AV cassette sensor (AVSW) is provided for distinguishing AV labels cassettes from TZ cassettes. With the states of those sensor switches, the CPU identifies the tape width, ink ribbon type of the tape cassette, and TZ/AV type, as listed in Table Fig shows the cassette sensor and AV cassette sensor circuit.

83 Error Messages (Displayed in Monitor) Communication error between PC and P-touch. The P-touch Monitor sends a status request to the P-touch, and if status information is not received from the P-touch within a set time, it assumes that a communication error has occurred. Communication error in P-touch. Transmission settings incorrect. A communication error occurs within the P-touch due to an over-run error, a communication buffer full error, etc. Not enough memory to print document. Not enough disk space to spool document. Advices (Deal with it in accordance with the thing of the following advice. ) Check for the following. For a serial port connection: 1. The enclosed interface cable should correctly connect the P-touch to the PC. Some commercially available RS-232C cables do not have the correct connectors. This type of cable can be used if it is connected to a modem, but it will not work correctly with the P-touch. In addition, the P-touch and PC must be directly connected to each other. Using an extension cable may cause a transmission error. 2. Another application or driver should not use the serial port that the P-touch is connected to. If a Microsoft Exchange modem is using the same port as the P-touch, the P-touch will not operate. If the port for the Exchange modem cannot be changed, do not try receiving mail. Otherwise, specify a different port such as one using infrared connection software or the LPT2 port. Be careful with pre-installed fax/modem boards, since some select COM1 for the fax. 3. The P-touch should be turned on. If a transmission error occurs with the P-touch, turn it off, and then on again. 4. The baud rates of the PC and the P-touch must be the same. Start up the PT-9500PC utility, and then set the baud rate. Delete the current print job before starting up the the PT-9500PC utility. For a USB connection: 1. Check that the P-touch is connected to your computer with the USB interface cable (that comes with the P-touch). Also check the cable for weak connection. 2. Make sure that the P-touch is turned on. If any communications error has occurred, turn the P-touch off and then on. For Windows 98/98SE/Me: 1. If more than one P-touch is connected to your computer via the USB interface, then you need to choose the correct printer port specifying the model name and serial number (e.g., PTUSB (PT- 9500PC-xxxxxxxxx): ), instead of the default printer port PTUSB:. Where, xxxxxxxxx is a serial number. Note: More than one P-touch may be connected to your computer, but only one P-touch may print at one time. Start up the PT-9500PC utility, and then set the baud rate. Delete the current print job before starting up the PT-9500PC utility. Start up the PT-9500PC utility, and then set the baud rate. Delete the current print job before starting up the PT-9500PC utility. Wait until any other application(s) is finished and then try to print again. Ensure sufficient disk space. IV - 7
