    CHAPTER 2 OPERATION AND TIMING 1. This chapter describes the envelope feeder 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 17: Basic Operation

    CHAPTER 2 I. BASIC OPERATION A. Outline The envelope feeder feeds envelopes into the printer. The envelope feeder is controlled by the pick-up commands (1st Start and 2nd Start) sent from the DC controller in the printer. Operation sequences of the envelope feeder are controlled by the envelope feeder driver PCB. A 4 bit microcomputer (CPU, IC932) and a gate array (G.A., IC931) are installed on the PCB.

  • Page 21 CHAPTER 2 B. Multi-feed Prevention Mechanism This envelope feeder utilizes the separation roller method to prevent feeding multiple envelopes. The upper separation roller is driven by the motor via a torque limiter. The upper separation roller is imparted with rotational force in the direction of the outlined arrow. However, as the upper separation roller, envelope and lower separation roller are in contact with each other, the rotational force of the lower separation roller is transmitted to the upper separation roller via the envelope and the upper separation roller rotates in the direction of the solid arrow (as shown in...
