  • Page 11: 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 12: 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. The operation is basically divided into three separate operations: feeding a document into the Film cartridge, compression-feeding the films, and ejecting the laminated document.
  • Page 13 B. Compression-feeding the films 1. The SG motor mounted at the right of the chassis runs to rotate the Control cam gear (also mounted at the right of the chassis) to its prescribed position. 2. As the Control cam gear rotates, the LF change shaft is rotated to its prescribed position by the cam on the Control cam gear.
  • Page 14 Continuous Mode When the second or subsequent document are inserted in the Continuous mode, the operation C described below feeds the documents to the prescribed position. C. Feeding Document Only into Film Cartridge 1. The SG motor mounted at the right of the chassis runs to rotate the Control cam gear (also mounted at the right of the chassis) to its prescribed position.

  • Page 15: 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 The SG motor drive rotates the Control cam gear to its prescribed position.
  • Page 16 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 assy via the spiral mechanism (not illustrated).

  • Page 17: 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, the Actuator top operates about the pivot to turn on the Paper sensor and detect the document leading edge. 2.
  • Page 18 Paper Width Detection (Y-CA sensor) 1. As the Y-cutter arm (Y-CA sensor carriage) moves in the direction of the arrow, the document contacts the Actuator Y, which rotates about the pivot to switch off the Y-CA sensor (photosensor). 2. When the Y-CA sensor turns off, the Y-cutter arm movement stops and this position is detected as the document width.

  • Page 19: Trimming Mechanism

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

  • Page 116: Detector Circuits

    5.4 Detector Circuits These circuits detect the status of the switches and keys that operate the machine (Two-connection switch, Start key, Stop key, Dial switch, Continuous key, and Extra border key) and the sensors that determine the film type, document length and width, and cover open/closed status.
  • Page 117 Switch Scan Circuit This circuit in the main CPU scans the status of the FEED • CUT • START • STOP • CONT • EXTRA BORDER key, and TRI switch (leaf switch) at 15 ms intervals to continuously detect the status of each switch. The circuit comprises a matrix of three output ports (P90, P91, P92) and three input ports (P93 to P95).
  • Page 118 Dial Switch Circuit This circuit detects the automatic cutting mode selected on the Cutting mode selector switch. This circuit comprises two push switches (RSW1, RSW2) mounted on each side of the dial switch. The signals detected by these two push switches are input to the Main PCB via the Switch PCB.
  • Page 119 Paper Width Detector Circuit (YCA-F sensor PCB) 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 PH1 mounted on the Paper width detector PCB that is attached to the Y-carriage.
  • Page 120 Cartridge Type Detector Circuit This circuit detects the type of film cartridge. The Cartridge type detector switch CSIZE3 is mounted at the film cartridge inlet. When an A3 film cartridge is inserted, the A3 film cartridge presses the Cartridge type detector switch CSIZE3 and turns it ON (P14 becomes LOW). The Cartridge type detector switch CSIZE4 is mounted at the film cartridge inlet.
  • Page 121 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 125: 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), and the filter circuit. The 2-channel switching power IC (IC#1) 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 126 +5V Power Supply Fig. 5.6-2 shows the timing chart of the power IC (IC#1) for the +5V DC power supply during idling. In this circuit, the transistor Q3 switches at approximately 100 kHz to convert the unstabilized input voltage to a stabilized +5V supply. When transistor Q3 is ON, energy accumulates in the coil L3 and electrolytic capacitor C10 until they are able to supply a +5V voltage.
