    CHAPTER 2 OPERATION AND TIMING 1. This chapter describes the paper deck functions, the relationships between mechanisms and circuits, and the timing of operations. Mechanical linkages are indicated by black and white lines ( ), the flow of control signals by solid arrows ( ), and the flow of groups of signals by outline arrows ( 2.

  • Page 15: Basic Operation

    CHAPTER 2 I. BASIC OPERATION A. Outline The paper deck feeds print paper to the printer. The sequence of paper deck operations is controlled by the paper deck driver PCB. This PCB contains an eight-bit microcomputer (IC201) to control the sequence of operations and serial communication with the option controller PCB.

    CHAPTER 2 II. PICK-UP/FEED SYSTEM A. Outline On receiving the pick-up command from the option controller, the paper deck driver starts paper-pick up operation. The paper is picked up by the pick-up roller and fed into the feed unit by the feed roller 1 and the separation roller. The paper stops after its skew is corrected by the registration roller.

  • Page 22 CHAPTER 2 B. Paper pick-up 1. Pick-up operation This paper deck conducts paper pick-up operation by lifting the paper to the paper pick-up position with the lifter and lowering the rotating cassette pick-up roller to the paper level. Paper pick-up operation is conducted only when the paper deck driver receives the pick-up command from the option controller.

  • Page 26 CHAPTER 2 b. Lift-up operation The lift-up operation is executed by the paper deck drive motor when a cassette is installed or the pick-up roller shaft is set lower than certain level due to the paper reduce. The two cases for the lift-up operation are as follows. Cassette pick-up cam Pick-up roller Feed roller 1...
  • Page 27 CHAPTER 2 1) Cassette is installed When a cassette is installed, the paper deck drive motor rotates, and the cassette paper pick-up solenoid (SL3) is turned ON. Then, the shaft drive arm is driven by the cassette paper pick-up cam rotation through the gear. Cassette pick-up cam Shaft drive arm Paper deck drive motor drive...
  • Page 28 CHAPTER 2 As the shaft drive arm goes down, the pick-up roller shaft goes down. Then, the lift-up release arm is pushed, and the lift-up cam is unfixed. At the same time, the shaft drive arm is fixed to the pick-up roller shaft fixing arm, and the pick-up roller shaft is stopped in the designated position.
  • Page 29 CHAPTER 2 The pick-up roller shaft is lifted up when the paper on the paper lifting plate touches the pick-up roller. Then, the fixing arm is released, and the lift-up release arm lifts up the pick-up roller shaft to the waiting position by force of the spring. At the same time, the lift- up cam is fixed by driving the pick-up roller shaft fixing arm and the lift-up release arm.
  • Page 30 CHAPTER 2 2) Paper level is lower than certain level As the paper level lowers, the moving distance of the pick-up roller increases. When the moving distance reaches the specified value, the pick-up roller shaft pushes the lift up release arm, and the lift up cam is unfixed. •...
  • Page 31 CHAPTER 2 When the lift-up cam is unfixed, the lift-up arm lifts up the lifter gear one tooth by the rotation of the lift-up cam. The paper lifting plate is lifted up by repeating the operation. (See Figure 2-2-9) When the paper on the paper lifting plate touches the pick-up roller, the pick-up roller shaft is lifted up.
  • Page 32 CHAPTER 2 c. Multi-feed prevention mechanism The paper deck utilizes the separation roller to prevent feeding multiple sheets of paper. Normally the separation roller is imparted with the rotational force in the same direction as that of the feed roller. However, since the separation roller has a torque limitter, it is rotated in the opposite direction by the rotational force transmitted from the feed roller 1 via the picked up paper.
  • Page 33 CHAPTER 2 C. Paper Jam Detection The following paper sensors are installed to detect the presence of paper and ensure that the paper is fed correctly. • Registration paper sensor (PS1) • Paper jam sensor (PS2) The CPU on the paper deck driver PCB determines whether or not a paper jam has occurred by monitoring the paper at each sensor according to the pre-set 'check timing' in the memory.
  • Page 34 CHAPTER 2 III. POWER SUPPLIES A. Outline The power supply unit of this paper deck employs the remote switch method. When the printer is turned ON, it outputs a command to the option controller via the video controller. Based on this command, the option controller outputs the POWER-ON signal (PWRON-IN) to the power supply unit via the paper deck driver.
