    Chapter 7 7.1 Overview/Configuration 7.1.1 Overview 0016-1844 The pickup/feeding system is the part to pickup and feed a paper, and it is composed of the main motor, solenoid, and various motors. In this machine, a paper is picked up from either the pickup tray or the manual feed tray, and it is delivered from the delivery tray. A paper set in either the pickup tray or the manual feed tray is picked up with the same pickup roller.
  • Page 78 Chapter 7 The pickup/feed operation of the machine is explained below. 1) Right after the DCONT board receives a print command from the SCNT board, it rotates the main motor (M1). By doing so, other rollers, except the pickup roller, start to rotate. 2) When it becomes initial rotation ready state, the pickup solenoid (SL1) turns ON for about 0.2 sec.
