  • Page 10: Mechanical Operating Principles

    2.1 Mechanical Operating Principles 2.1.1 Description of Mechanisms (Border Mode) 1. When a document is inserted into the paper loading gate, the paper feed rollers feed it to the driving roller. 2. As the document passes between the paper feed rollers, the paper size detector determines its size (length and width).
  • Page 11: Feed And Compression Mechanisms

    2.1.2 Feed and Compression Mechanisms The feed and compression mechanism controls the motor drive to feed the document into the film cartridge, compression-feed the films, and eject the laminated document. When no compression-feed is applied while feeding a document into the film cartridge or ejecting a laminated document, the LF motor rotates clockwise and the motor drive is transmitted via gears to the paper feed roller and paper eject roller.
  • Page 12 Operation During Film Compression-Feed 1. When the leading edge of the document enters the compression-feed area, LF motor starts to rotate counterclockwise, as indicated by the arrow. 2. Planet gear (A), which had been free, moves to engage with drive gear (A). The drive from the LF motor is then transmitted to the various gears, as shown in the diagram, and the driving roller rotates as indicated by the arrow.
  • Page 13: Cutter Mechanism (border Mode)

    2.1.3 Cutter Mechanism (Border Mode) The cutter mechanism cuts the laminated document to the size of the document plus an added border. Both edges of the films are cut to suit the width of the document and the leading edge and trailing edge are cut according to the document length. Y-Cutter Vertical Drive Operation 1.
  • Page 14 Cutting Leading and Trailing Edges (X-cutter Mechanism) 1. All the rollers which feed the document stop when the cut position at the leading edge of the document reaches the cutting position of the rotary cutter and fixed- blade cutter. 2. The DC motor rotates to drive the carriage in the X-cutter assembly via the spiral mechanism (not illustrated).
  • Page 15: Paper Size Detector Mechanism

    2.1.4 Paper Size Detector Mechanism Paper Length Detection 1. When the leading edge of the document passes between the paper feed rollers, it rotates the paper sensor crank about the pivot to turn on the paper sensor which detects the document leading edge. 2.
  • Page 16 Paper Width Detection 1. The Y-cutter arm L (sensor unit) moves in the direction of the arrow. When the PL detect lever touches the document, it rotates about the pivot to switch off the photosensor. 2. When the photosensor turns off, the Y-cutter arm L movement stops and this position is detected as the document width.
  • Page 17: Trimming Mechanism

    2.1.5 Trimming Mechanism 1. When a corner of the laminated document is inserted over the T-cutter plate, the sensor lever operates a leaf switch that detects the document. 2. When the document is detected, the motor gear of TC motor rotates in the direction of the arrow (counterclockwise) from its reference position to drive the T-cam gear in the direction indicated by the arrow (clockwise) via a series of gears.

  • Page 115 Buzzer Drive Circuit This circuit sounds the piezoelectric buzzer. To sound the buzzer, the main CPU outputs a 4 kHz squarewave with 50% duty from port DV0 (P13). This signal is used to generate the buzzer sound. To stop the buzzer, the port status is set to High level using R82 in the input mode. Fig.
  • Page 116 Specification Switching Circuit This circuit reads the specification switching information. The specification switching is conducted by a ROM program built into the main CPU according to the solder point settings on the PCB. The relationships between the solder points and specifications are shown in PART LIST.
  • Page 117: Detector Circuits

    5.4 Detector Circuits These circuits detect the status of the switches, keys and buttons that operate the machine (Power switch, Cut key, Feed key, Start/Stop button, and dial switches) and the sensors that determine the film type, document length and width, and cover open/closed status.
  • Page 118 Switch Scan Circuit This circuit in the main CPU scans the status of the Power switch, Cut button, Feed button, Start button, and TRI switch (leaf switch) at 14 ms intervals to continuously detect the status of each switch. The circuit comprises a matrix of two output ports (P36, P37) and four input ports (P40 to P43).
  • Page 119 Dial Switch Circuit This circuit detects the automatic cutting mode selected on the Cutting mode selector switch. This circuit comprises two leaf switches (ON/OFF-R, ON/OFF-L ) mounted on each side of the dial switch. The signals detected by these two leaf switches are input to the Main PCB via the Switch PCB.
  • Page 120 Paper Width Detector Circuit This circuit detects the width of the document and determines the Y-carriage position. It also determines the Y-carriage standby position when the power is ON or the cover is closed. This circuit comprises the transmissive photosensor YCA-F mounted on the Paper size detector PCB that is attached to the Y-carriage.
  • Page 121 Cartridge Type Detector Circuit This circuit detects the type of film cartridge. The cartridge type detector switch CSIZE is mounted at the film cartridge inlet. When an A4 film cartridge is inserted, the film cartridge presses the cartridge type detector switch and sets the input Low (ON). When no cartridge or an A6 film cartridge is inserted, the input remains High (OFF).
  • Page 122 Film Feed Detector Circuit This circuit detects the film feed status to prevent jams if a problem occurs. The film feed detector switch TPS is mounted before the paper eject roller and if there’s no problem with the film during document feed or compression, the film presses against the film feed detector switch TPS and sets the ON (input Low).
  • Page 123: Motor Drive Circuits

    5.5 Motor Drive Circuits Paper Feed Motor Drive Circuit (LF Motor) This circuit drives the paper feed motor using 2-2 phase excitation from the +24V DC stabilized constant voltage. The stepping motor excitation phases A, B, C, and D are controlled by main CPU ports P72, P73, P70, and P71, respectively.
  • Page 124 Trimming Motor Start Point Detect Circuit This circuit rotates the trimming cam and Y-cutter cam forward and backward with the trimming motor (T/C motor) to detect the position of each cam. The trimming switch (TRG) is designed to turn OFF 150 steps before the trimming cam standby position (T-cutter top position).
  • Page 125 X-cutter Motor Drive Circuit This circuit drives the DC motor with the +24V DC stabilized constant voltage. The X-cutter comprises a DC motor and two switches. The DC motor is controlled by the main CPU ports P14 to P17 and is driven by the DC motor control driver #4. The two switches are detected by ports P53 and P54.
  • Page 126: Power Supply Circuits

    5.6 Power Supply Circuits The power supply circuits receive the unstabilized DC voltage supplied to CN1 from the AC adaptor through the Jack PCB via fuse F1 (protective circuit), diode D6, and the filter circuit. The 2-channel switching power IC (IC#6) in the circuits converts the unstabilized DC voltage into a stabilized +5V voltage (logic power supply) and into a stabilized +24V DC voltage (drive power supply).
  • Page 127 +5V Power Supply Fig. 5.6-2 shows the timing chart of the power IC (IC#6) for the +5V DC power supply during idling. In this circuit, the transistor Q11 switches at approximately 100 kHz to convert the unstabilized input voltage to a stabilized +5V supply. When transistor Q11 is ON, energy accumulates in the coil L3 and electrolytic capacitor C27 until they are able to supply a +5V voltage.
