  • Page 21: System Description

    3 SYSTEM DESCRIPTION The CF Series Scanner is a highly versatile data capture device, providing choices in speed and resolution and producing high quality data. It also allows a choice between using a fixed threshold or an adaptive threshold. An adaptive threshold takes into account variations in the shading of the media to yield consistently good results, even from less than optimal documents.

  • Page 22: Major Systems Of Scanner

    3.1 MAJOR SYSTEMS OF SCANNER To provide a general overview of how the CF Series Scanner works, the remainder of this section will discuss the various systems that comprise the scanner. 3.1.1 Scanner Control System The CF Series Scanner may be controlled by the host computer, by the optional keypad on the scanner itself, or a combination of the two.

  • Page 23: Document Illumination System

    Two pulley-driven drive rollers, one on each side of the scan window, are located on the bed of the scanner. Applying pressure against these two drive rollers are two free-turning rollers mounted in the lid of the scanner. Three light sensitive sensors determine the position of the document.

  • Page 24: Display System (Optional)

    3.1.8 Power Supply System The CF Series Scanner operates on 110 or 220 V.A.C. (determined at the time of purchase). A circuit breaker on the rear panel provides protection on the A.C. input line.

  • Page 25: Ventilation System

    The logic boards, 100 Watt lamps, and power supplies produce significant amounts of heat. A series of vents in the left side cover of the scanner allow air to enter the scanner for cooling purposes. A metal mesh air filter covers the air intake vent.
  • Page 26 This page intentionally left blank.

  • Page 27: Preventive Maintenance

    Once a month (or more often if conditions warrant it), remove the metal mesh filter located in the bracket on the left inside panel of the scanner. Wash the filters in warm water, air dry them, spray them all over lightly with filter spray (A64168), and reinstall them.

  • Page 28: Check Power Supply Voltages

    4.3.2 Check Power Supply Voltages Open the front of the scanner cabinet, refer to the Figure of the Power Supply Assembly found in this manual and Section 6.7, and check the voltages at the test points on the power supply.

  • Page 29: Diagnostic Software

    5.1 On-Board Diagnostic System The Main Menu shown in Figure 5-7 is typical for a CF Series 1000 scanner. The Main Menus for the other CF Series Scanners are similar. The functions on the Main Menu are the same as those on the keypad and the scanner can be operated from either device.
  • Page 30 Menus pop up in response to most choices on the Diagnostic Tests menu. Simply enter the desired value or parameter and the function will be performed or its menu will be accessed.
  • Page 31 This page intentionally left blank.

  • Page 32: Set Global Parameters

    When you press <1> for “Set Global Parameters,” a menu display similar to that in Figure 5-9 appears. The values shown in this example are typical for a CF Series 1000 scanner. If you do not want to change anything, press <X> to exit and return to the Diagnostic Tests Menu.
  • Page 33 NOTE: The bar pattern is useful for troubleshooting because it isolates the “front end” electronics -- the CCD cameras and the Video Board from the rest of the scanner. If the bar pattern is good, the problem is either in the cameras or Video Board. If the pattern is bad, the problem most likely occurs after that point.

  • Page 34: Parameter Backup

    Further, if alteration is necessary, as a precaution, power the scanner off and then on again to reset all the current parameter values. Then change only those which need changing. Then commit them to the backup memory.

  • Page 36 5.1.4 Set Motor Speed (4) Press option <4> to set the motor speeds to be used for each resolution. The Resolution Index is a common index which combines a set of parameters -- resolution (samples taken per inch), motor speed, and the splice count. Lower resolutions run at a faster speed than high resolutions.
  • Page 37 The number of resolutions entered in the Global Parameters will determine the functionality of this table. For example, the CF 300 with three resolutions will use motor speed values entered in A through C when different resolutions are selected from the Main Menu. If you press <T>...
  • Page 38 5.1.5 Splice Counts (5) The Splice Counts option provides a method to list and modify line splice settings. The counts are usually set interactively through choice 8, "Merge & Splice Adjustment," on the Diagnostic Tests menu ( see 5.1.8 ) . When you press <5>, a display similar to Figure 5-12 will appear.
  • Page 39 This page intentionally left blank.

  • Page 45 This page intentionally left blank.
  • Page 46 For testing magnification, this option scans precisely drawn lines on a test chart and calculates the distance between them as perceived by the scanner. This value is then compared to the actual known value. Each CCD camera contains an array of 5312 pixels. When operating within specification, each camera should detect at least 5100 pixels.
  • Page 47 Procedure for Adjusting Camera Magnification: The first four steps of this procedure -- as well as the required equipment, tools, and materials - - are the same as for adjusting the focus of the camera. NOTE: In practice, both the focus and magnification of a given camera should be set before moving on to the next camera because of the need for precise placement of the Standard Test Document.
  • Page 48 NOTE: On CF 300/44 models, the multiple should be 60, rather than fifty. If you have this model, please use the following table to find the values.

  • Page 52 5.1.8 MERGE AND SPLICE ADJUSTMENT (8) This feature lets you precisely adjust the effective camera position to eliminate discontinuities across camera boundaries. Merging is adjustment along the scan line. Splicing is adjustment perpendicular to the scan line. ______________________________________________________________________ NOTE: Focus, magnification, merge, and splice functions are intertwined. If you adjust one, you must test and, if necessary, adjust the other functions.
  • Page 53 • Delay counts*: This field shows the splice values between each camera in the scanner. Place the standard test document, illustrated in figure 5-18, in the scanner to demonstrate the camera merge and splice.
  • Page 54 • F (fast) Allows you to speed up document travel to get to a specific place on the document. It toggles between “fast” and the scanning speed previously set. • X (exit) Press <X> to exit the Merge and Splice Adjustment menu and return to the Diagnostic Test Menu.
  • Page 55 This page intentionally left blank.
  • Page 56 If one camera encounters data before adjacent cameras do, that means it is tilted too far towards the front of the scanner. If it encounters data after its neighboring cameras, it is tilted too far back.
  • Page 57 The system makes merge adjustment electronically and has a design overlap of 64 to 128 pixels depending on the model of a scanner. To adjust merging, you can delete up to 256 pixels from each camera’s data stream. Each merge adjustment is independent so that adjusting the merge between one pair of cameras does not affect the merge between any other pair of cameras.
  • Page 58 A : RUN AUTOSIZE SEQUENCE Figure 5-24 Set Autosize Parameters Menu Press <A> to run the auto sizing sequence. Feed in a document, then wait for the scanner to analyze it and display its width on the display terminal. • If the scanner is missing document edges and returning document width values that are two narrow, one or both of the autosizing parameters may need to be decreased slightly.
  • Page 59 Non-volatile RAM (NVRAM) on the CALS Board. If you press <N>, the current values will be retained until you change them or the scanner is turned off. In either case, the operative values will be displayed as shown in figure 5-25.
  • Page 60 Choice <4> starts the motor. The rollers should begin turning. The motor will not run if the scanner top cover is open. Choice <5> stops the motor . The rollers should stop. Choice <6> reverses the motor direction. If the motor is on, direction will reverse immediately.
  • Page 61 If you enter <7>, messages will come up showing which sensors are on (detecting something in their path). The sensors are identified as: A (before first roller) ; B (between first roller and scan window) ; and C (right after scan window). When this test is selected, a message similar to the one shown in figure 5-27 will appear.
  • Page 62 This should be a dark blue or black A size document. Align it to the rightmost edge of the active scan area marked by a black line on the scanner top plate. Page Offset determination will now proceed automatically. The determined offsets will appear dynamically in the table as they are calculated.
  • Page 63 This page intentionally left blank.
  • Page 64 Figure 5-30 Camera System Diagnostics Menu 5.1.14.1 E: Exposure Memory Exposure in the CF scanner is similar to shutter speed in a conventional camera. The higher the number (the slower shutter speed), the longer the camera is collecting data. This memory stores data telling the camera when to start collecting data.
  • Page 65 If you enter <C> for “Load Exposure for One Camera”, the prompt “Camera Number”will appear. Enter the number of a camera (such as 0,5, or 6) in your scanner. The next prompt is “Exposure Time (Pixels)”. Enter the count (in 200 nanosecond units) that represents the time it takes the camera to collect light.
  • Page 66 On the X-axis is the pixel number and on the Y-axis is the light response of the pixel (pixel value). The scanner will then begin automatically calibrating all the cameras, one by one. Messages will appear on the screen telling you which camera is being calibrated. The number you see on the left hand side under the camera number is the exposure time which starts with the number entered at the first prompt.
  • Page 67 5.1.14.3 G : Gain Memory Gain control allows light response equalization for each CCD photosite in the scanner. This is required because the amount of light transmitted through the lens is greatest in the center and tapers off towards the edges. Also, the response of individual photosites varies somewhat due to limitations in the manufacturing process.
  • Page 68 5.1.14.5 D : Display Calibration Memory If you enter <D> and a <CR> for “Display”, the contents of the Calibration Memory will be displayed, starting from address 0000.

  • Page 74: Resolution Control

    “Divisor” is the ratio of maximum resolution to scanning resolution. For example, a CF1000 scanner has a maximum resolution of 1000 pixels/inch. If scanning resolution is 500 pixels/per inch, the divisor is (1000.0)/(500.0) = 2.000. Calculate the required divisor values in this way before setting new resolutions.
  • Page 75 The prompt, “Pixels/Inch:”, will appear. Enter the number of pixels resolved per inch in decimal followed by a <CR>. At this point, the prompt “Display String:” will appear. Enter a four-character reference that is significant to your operators, such as “LASR” for laser printer output or “FULL” for full resolution or “500”...

This command is used in the manufacturing process when creating a new scanner. It should be used in the field only when the NVRAM contents have been destroyed by a hardware failure.
  • Page 79 This page intentionally left blank.
  • Page 80 Parameter ______________ The scanner computes a sum of the pixels in the selected neighborhoods ( foreground pixels are given value 1 and background pixels are given value 0 ) and compares it against a threshold parameter. This comparison determines whether a pixel is removed or filled in. The strength of the filter is determined by the threshold value.
  • Page 81 Commands : <P> Choose Parameter Set The prompt “ Parameter Set ( A,B,C,D ) : “ will appear. When you enter a letter, the corresponding set will be displayed. <S> Set Parameter Sets one of the parameters within the currently selected set.
