  • Page 70: Detecting The Presence/Absence Of An Original

    Chapter 3 3.3.2 Detecting the Presence/Absence of an Original 0013-3469 The presence/absence of an original in the original tray is detected by the original sensor (S6). When an original is placed on the original tray, the light from the light-emitting side of the original sensor is blocked, causing the light-receiving side of the original sensor to send the original detection signal (DTS) to the ADF controller PCB, which in response turns on the Original Set indicator.

  • Page 71: Original Size Detection 1

    Chapter 3 3.3.3 Original Size Detection 1 0013-3470 In original size detection 1, the original trailing edge sensor is used (S7), which is designed to identify the original in the original tray as being small-size or large-size. When the original covers the original trailing edge sensor, the light from the LED of the original trailing edge sensor is reflected by the original to hit the phototransistor, at which time the DADF identifies the original as being large-size.

  • Page 72: Original Size Detection 2

    Chapter 3 3.3.4 Original Size Detection 2 0013-3471 A. Outline In original size detection 2, the original width detecting switch (SW301) and the registration roller clock sensor (PI5) are used to identify a default size. The original width detecting switch is designed to find out the width of originals. As many as five contact plates (SSW0 through 4) are in contact with the original width detecting switch, operating in keeping with the slide guide.
  • Page 73 Chapter 3 The registration roller clock sensor (PI5) is used to measure the length of originals with reference to the revolutions made by the clock plate mounted to the slave roller of the registration roller. Based on the revolutions of the lock plate, the ADF controller PCB identifies the length of the original in question (in feeding direction).

  • Page 75 Chapter 3 B. Slide Guide Lock The DADF is equipped with a slide guide lock so that the slide guide will not slide beyond the width of an A4/ A3 sheet. To use an original wider than 297 mm, remove the slide guide lock (up to 305 mm; however, the feeding length must be 432 mm or less).
