CHAPTER 2 OPERATIONS AND TIMING 2.3 Detecting Originals 2.3.1 Outline The DADF is equipped with the following five types of mechanisms of detection: Item Description Presence/absence of an original Original size 1 Original size 2 Pre-last original Original in manual feeder Sensor used (notation) Identifies the presence/absence of an original on the original tray. Identifies the size of the original placed in the original tray (as to being large-size or small-size).
PAGE 37
CHAPTER 2 OPERATIONS AND TIMING 2.3.2 Detecting the Presence/Absence of an Original 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 38
CHAPTER 2 OPERATIONS AND TIMING 2.3.3 Original Size Detection 1 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 39
CHAPTER 2 OPERATIONS AND TIMING 2.3.4 Original Size Detection 2 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 40
CHAPTER 2 OPERATIONS AND TIMING 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 41
CHAPTER 2 OPERATIONS AND TIMING The following tables show the default sizes in relation to the sizes detected by the DADF: A- and A/B-Configuration Default size Original length (unit: mm) Original width B5R 237 to 297 177 to 187 A5 129 to 189 205 to 213 A4R 277 to 317 FOOLSCAP 317 to 370 B5 162 to 222 252 to 262 B4 344 to 404 COMPUTER 361 to 421 274.4 to 284.4 paper A4 190 to 250 292 to 302 A3 400 to 460 A size outside of the above ranges will be identified as a non-default size.
PAGE 42
CHAPTER 2 OPERATIONS AND TIMING 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). Slide guide lock F02-203-06 Be sure to adjust the slide guide to suit the original size when making copies. Otherwise, the original is likely to move askew. 2-22 COPYRIGHT © 2001 CANON INC.
PAGE 43
CHAPTER 2 OPERATIONS AND TIMING c. Slide Guide Positioning Member The rail of the slide guide is provided with notches to make sure that the slide guide stops to suit a specific default original size. Some of these points representing differing paper sizes, however, are close enough to allow the slide guide to be set at the wrong point.
PAGE 44
CHAPTER 2 OPERATIONS AND TIMING 2.3.5 Pre-Last Original Detection Pre-last original detection makes use of the pre-last original sensor (S8). Detection is executed on small-size originals only. The DADF is designed to send the second original to the separation assembly after it has picked up the first original (small-side). At that time, if no original covers the pre-last original sensor (S8), the dada will assume that no original will follow, and communicates as such to the copier.
PAGE 45
CHAPTER 2 OPERATIONS AND TIMING 2.3.6 Detecting the Presence/Absence of an Original in the Manual Feeder The presence/absence of an original in the manual feeder is detected using the manual set sensor (PI12). When an original is placed in the manual feeder, the original pushes the sensor flag, causing the sensor flag to reach the sensor, enabling the DADF to assume the presence of an original in the manual feeder.
PAGE 46
CHAPTER 2 OPERATIONS AND TIMING 2.4 Picking Up and Separating Originals 2.4.1 Outline The pickup roller unit is butted against the original, and the pickup roller is rotated to pick up an original. The pickup roller unit is moved up/down by the pickup motor (M3), and the pickup roller is rotated by the separation motor (M4) and the separation clutch (CL). Originals are separated by the separation roller and the separation belt with the help of the feeding roller.
PAGE 47
CHAPTER 2 OPERATIONS AND TIMING 2.4.2 Moving Up/Down the Pickup Roller Unit a. Outline The DADF is equipped with two pickup roller units, each designed to move up/down between home position and the surface of the stack of originals. The pickup roller unit is moved up/down by the pickup motor (M3). The pickup roller unit stops at either of the following positions; positioning is controlled by means of pulses from sensors and the pickup motor.
PAGE 48
CHAPTER 2 OPERATIONS AND TIMING M3 M3 Pickup roller unit 1 mm (approx.) b.Movement When the Start key on the copier is pressed, the DADF’s stopper plate moves down and the pickup motor (M3) starts so that the pickup roller unit moves down to reach the stack of originals. The pickup motor will stop when the pickup roller unit has reached the pickup height sensor 1 (PI8) and the pickup height sensor 2 (PI9) and then has moved down about 1 mm.
PAGE 49
CHAPTER 2 OPERATIONS AND TIMING When the leading edge of the 1st original reaches the separation sensor (S4), the pickup motor (M3) starts to rotate to move the pickup roller unit from the surface of the stack of originals. The pickup roller unit stops about 6 mm from the surface of the stack of originals. 6 mm (approx.
PAGE 50
CHAPTER 2 OPERATIONS AND TIMING 2.4.3 Switching the Separation Pressure The DADF’s separation assembly is equipped with a separation pressure switching mechanism which enables switching between two settings (low or high). The separation pressure may be switched by operating the separation pressure lever located in front of the separation assembly.
PAGE 51
CHAPTER 2 OPERATIONS AND TIMING 2.4.
PAGE 52
CHAPTER 2 OPERATIONS AND TIMING Both separation sensor and skew sensor are used to find out whether an original is moving askew. These two sensors are arranged in a single row in front-rear direction. An original is identified as moving askew if a discrepancy in timing is detected when it moves past these sensors.

CHAPTER 2 OPERATIONS AND TIMING 3 Jams The DADF uses the sensors shown in F02-301-03 to detect a jam. The timing at which jam detection is tuned on is programmed in advance in the CPU on the ADF controller PCB, and the presence/absence of a jam is detected in relation to the presence/absence of paper over a specific sensor. When a jam is detected, the DADF communicates the fact to the copier in the form of a code, and some copiers allow a check on jam codes in service mode.

CHAPTER 2 OPERATIONS AND TIMING 4 Power Supply The following is an outline of the power supply system. The DADF’s power supply receives from the copier two types of 24 V; one (input to J4-1) is supplied to each load by way of a fuse (FU1), while the other (input to J1-6) is supplied to the sensors and the ADF controller PCB after conversion into 5 V by a regulator (Q28) and into 5.8 V by another regulator (Q65).
