CHAPTER 2 FUNCTIONS & OPERATION 2. Shading This section explains the reading mechanism of the white reference sheet for determination of the shading correction value. The sectional view of the reading unit is shown below. White reference sheet White reference sheet Figure 2-202 This machine can read the white reference data at the document reading position, unlike other scanners having the black background color, since its background color is white.
CHAPTER 2 FUNCTIONS & OPERATION III. FEED SYSTEM 1. Feeding Mechanism The sectional view of the feed system is shown below.
CHAPTER 2 FUNCTIONS & OPERATION 1) Feed path The feed path in this machine is horizontal in the reading unit, and has the two types of straight or U-turn in the eject section. When feeding cards, use the straight path. 2) Drive The pickup, feed, and retard rollers in the early stage are driven by the feed motor, and from the registration roller to the eject roller in the later stage are driven by the main motor. The scanning condition determines each drive speed.
CHAPTER 2 FUNCTIONS & OPERATION a. 5) Eject This machine is equipped with both a U-turn path and a straight path. The selection is made by opening or closing the straight eject tray. This is what operates the flapper. The difference is shown in the following figures. Feed roller Retard roller a. U-turn path b. Figure 2-303 However, if the lever is in none separate feed, the retard roller is allowed to rotate freely, and the document is fed by the rotation of the feed roller. b.
CHAPTER 2 FUNCTIONS & OPERATION 6) Sensor The document sensor is mounted on the inlet, the registration sensor is mounted before and after the registration roller, and the eject sensor is mounted immediately after the straight eject roller. Furthermore, the ultrasonic sensor for double feed detection is mounted in front of the registration roller. In addition, the skew sensors (R and L) are mounted in front of the registration roller in this device. This detects when the document is skewed.
CHAPTER 2 FUNCTIONS & OPERATION Ultrasonic receive sensor (reception) 2) Double Feed Detection There are 2 double feed detection methods: the document length detection by the registration sensor and the document overlapping detection by the ultrasonic sensor. Registration sensor The registration sensor uses the first document length of the scanned batch as a reference to detect the document length. The 35 mm or more difference from the standard is interpreted as a double feed.

Registration Adjustment You can execute both automatic and manual registration adjustment from the [Extended Setting] screen. a.
CHAPTER 5 TROUBLESHOOTING b. Manual Registration Adjustment Registration adjustment is normally performed in automatic mode. This manual adjustment is a mode that performs fine adjustment of the result of the automatic adjustment. Note that it does not reduce variations in the registration position. 5) After setting, always select the [Set] button. 0.4 ↓ -0.6 Adjustment sheet Use the same sheet as the scale parameter adjustment sheet. For details, refer to the “Scale Parameter Adjustment” section.
CHAPTER 5 TROUBLESHOOTING 3. Scaling Rate Control shown below. This mode adjusts the scale parameter to make the length of the image in the feed direction correct. It performs adjustment using the front side image. The same values are applied to the reverse side image as the front side. If the image leading edge position is different, perform registration adjustment first. TKM-0271 Types There are three types of scale parameter adjustment.
CHAPTER 5 TROUBLESHOOTING 2) Set the feed selection lever to “separate mode” or “none separate mode” as necessary. 3) Set the resolution, size and mode, and then select the [Scan] button. Note:To set both “separate mode” and “none separate mode”, do this twice. 4) The scanned image is displayed. (Refer to Figure 5-257) 5) Use [Zoom] to enlarge the leading edge of the image and ensure that the position of the leading edge is correct.
CHAPTER 5 TROUBLESHOOTING 2.0mm Figure 5-260 →0.67% Figure 5-259 Note:The adjustment might not be enough using the factory adjustment value alone. If this happens, use the user adjustment value as well. Or, replace the rollers. 7) Place the adjustment sheet and scan again. Check the displayed image. Note:Repeat the procedure again if the adjustments were not corrected properly. 5-34 COPYRIGHT © CANON ELECTRONICS INC.
