CHAPTER II THEORY OF OPERATION

2.1 OUTLINE OF MECHANISMS

2.1.1 Print Mechanism

Structure of Thermal Head

This machine adopts direct thermal printing system. The thermal head consists of 1296 pieces of heating elements arrayed in vertical single row as shown in the Fig. 2.1-1. The dimension of each heating element is vertical length 0.0847(0.0847mm pitch) x horizontal width 0.13mm.

Pitch 0.0847mm

0.13mm

Fig. 2.1-1 Heating Elements of Thermal Head

Printing Process

A thermal tape is pressed against the thermal head in the printing process by the force comes from a nip between the cylindrical rubber platen and the thermal head. At this timing, voltage is applied selectively to 1296 pieces of heating elements arrayed on the thermal head. By this voltage application, the heating elements generate heat and the thermal tape develops dots by itself at heat sensing points. After application of voltage the thermal tape is fed to the next printing position by the platen (0.0847mm). This printing cycle is repeated and characters and geometries are printed on the tape. One time travel distance (0.0847mm) is shorter than the width of a heating element (0.13mm), so that continuous printing cycle can print characters and geometries on a tape by developing dots with no gap.

II- 1

2.1.2 Press Contact and Release Mechanism of Thermal Head

The head ASSY is pressed firmly against the platen by the force of spring. When the release levers L and R are pulled upwards, they are unlocked so that the platen and top cover are released. The tape can be loaded into the machine in this status. If the head ASSY is pressed against the platen, close the top cover.

2.1.3 Tape Feed Mechanism

When the tape is fed, the tape is pressed against the thermal head, which is nipped between the platen and the thermal head. Here, the tape feed motor (step motor) rotates, of which drive power is transmitted via the gear train to the platen gear and the platen, and consequently the platen can feed the tape.

2.1.4 Automatic Tape Full Cutter Mechanism

The automatic tape full cutter mechanism moves the moving cutter blade up and down to the direction of the fixed cutter blade to cut the tape on the feeding pass. The cam is rotated once so that the moving cutter blade moves up and down and cuts a medium. The cutter motor rotates from the position where the cutter home position sensor is ON, and the gear of the cam is rotated through the cutter worm gear. When the cam is rotated once, the cutter motor stops and stays again at the position where the cutter home position sensor is ON. This mechanism provides the mechanism to reverse the driving system, which is used in case that the tape or the like is jammed between the blades. (For the details, refer to CHAPTER IV TROUBLESHOOTING & ERROR MESSEAGE.) When the driving system is reversed, the cutter motor stops and stays again at the position where the cutter home position sensor is ON.

2.3.1 Logic Components

[ 1 ] CPU CPU (U12) controls and manages the entire system, which is 32bit microcomputer of NEC brand.

[ 2 ] Flash ROM One 32M-bit flash ROM is used, where the program, font and downloaded data are stored.

[ 3 ] SDRAM One 64M-bit SDRAM is used. It is used when the program is executed, and when the received data is stored temporarily.

[ 4 ] EEPROM One 4Kbit EEPROM (U3) is used. This memory is used for write and storage of baud rate information, Vendor ID code, Product ID code and mechanical information. If the main PCB is replaced, it is needed to write the serial number printed on the EEPROM mounted on the main PCB and the mechanical configuration date. For this operation, refer to APPENDIX 1. MAINTENANCE SOFTWARE OPERATION.

II- 10

2.3.2 Key, LED Circuit

- Power supply ON/OFF circuit This circuit detects the state of ON/OFF of the ON/OFF button. Pressing this button in the power supply OFF state (LED OFF), LOW signal is sent to the CPU. Then the CPU starts initializing process and establishes the status of power supply ON (LED ON and ready for date acceptance from PC). Pressing this button in the condition that the status of power supply in ON and the status of ready for date acceptance from PC (LED ON), the CPU starts power OFF process, turns the LED OFF and changes the status into power supply OFF (LED OFF). Pressing this button in the condition that the status of power supply is ON and now going on printing, the CPU stops printing, starts power OFF process after reading and discarding the date sent from PC, and changes the status into power supply OFF (LED OFF).

2.3.4 Full Cutter Motor Driver Circuit and Media Feed Motor Driver Circuit

(1) Full Cutter motor driver circuit The circuit drives the DC motor to cut a medium as described in subsection 2.1.4 Automatic Tape Full Cutter Mechanism. When the CPU receives cut request from the key or software, it confirms that the top cover ASSY is closed, and turns VHON (91 pin) high. Then the CPU controls C_DCF (114 pin) and C_DCR (115 pin) to drive the cutter motor.

(2) Media feed motor driver circuit When the CPU receives feed request from the key, it confirms that the top cover ASSY is closed, and turns VHON (91 pin) high. Then the CPU controls SIN1 (27 pin) through SIN6 (20 pin) to drive the media feed motor.

(2) Media position detect sensor circuit When performing printing and FEED motion through the process described in subsection 2.3.4 (2) Media feed motor driver circuit, the CPU reads the sensor value to detect the medium position. The CPU receives the voltage of the media position detect sensor (reflection type photo sensor) sent through CN13 and input it through SENTAN (80 pin). The CPU processes this voltage through AD conversion and inspects the print mark on the back face of media that stays on the sensor position.

(3) Cover open sensor circuit QL-1060N has the cover open sensor. It identifies open/close of the top cover ASSY from the status of mechanical switch. Opening the top cover ASSY, the contact of cover open sensor on SB PCB opens. The change of status is sent as the signal through CN16 to COVER (34 pin) of the CPU. The CPU detects open/close of the cover from the change of voltage at 19 pin. The CPU stops all performances if detecting cover open during printing, FEED or CUT.

2.3.6 Head Temperature Detect Circuit

QL-1060N measures the following temperature. - Head temperature: The CPU determines the ambient temperature of the head from the AD

converted voltage value input to TH (78pin) of the CPU via CN11.

Fig. 2.3-9 Head Temperature Detect Circuit 2.3.7 Cutter Home Position Sensor Circuit

QL-1060N identifies open/close of the cutter from the status of mechanical switch. Closing the cutter, the cutter home position sensor opens. The change of status is sent as the signal through CN14 to CUTSEN (74 pin) of the CPU. QL-1060N first confirms that the cutter stays on its home position prior to printing. When the cutter returns to the home position, the cutter home position sensor circuit recognizes it and stops the DC motor rotation.

Fig. 2.3-10 Cutter Home Position Sensor Circuit 2.3.8 Reset Circuit

QL-1060N receives the electric power from the power supply PCB and output +5V and +3v to the CPU. When the power is supplied, the reset circuit (U13) returns high to reset input pin (66pin) of the CPU when detecting the voltage the +3V voltage line rises over +2.8V. This input releases the reset status of CPU. If the +3V voltage line drop to +2.8V or lower due to any reason during operation, the reset circuits returns Low signal to the CPU and the CPU goes to the reset status.
