10 3.2 Problems with the scanner installation Problem Error message during Scanner Calibration Cannot scan to a cloud service Possible Causes and Remedies This message may appear when running the Calibration wizard. 1. The most common cause is a dirty or smudged glass plate. Clean the scanning area, reboot the scanner and then complete the calibration steps as described in the section Full Calibration in this guide. 2. If the problem persists after cleaning the scanning area - the problem could be caused by a loose object in the optical path. Remove any torn pieces of paper or other loose objects from the scanning area. Even the smallest loose objects will disturb the scanner adjustment function. Contact your technical service provider if the problem persists. You get a message on the scanner screen: Welcome to Contex LINK, <cloud service name> is not enabled 1. Ensure that you have installed the Contex LINK client software on your PC, and that you have setup the parameters for the specific cloud service. 2. If you have made the settings, test your login credentials to the cloud service from your PC. 3. Repeat the cloud service setup in Contex LINK. Can t find myself as a user on the scanner Ensure that you have the latest version of the Contex LINK software on your PC. If not, update Contex LINK and repeat above steps. You scroll through the available users on the scanner screen and cannot find yourself as a user. Try the following steps: 1. Ensure that you have installed the Contex LINK client software on your PC, and that you have setup the user parameters correctly. 2. Restart the scanner to let it redetect all users on the LAN. If the above fails, update the Contex LINK software on your PC and repeat above steps. Page 10

11 3.3 Problems operating the scanner Problem I can t find my scan files after scanning Possible Causes and Remedies You selected scan to PC or scan to a cloud service but you cannot locate your scan file. 1.

12 Problem Scanning: The colors in my scan are not correct in relation to the original document Copying: The colors in my printed output were not copied correctly in relation to the original document Possible Causes and Remedies Please carry out a calibration of the scanner. Calibration adjusts the color settings. 1. Thoroughly clean the scanning area. See Cleaning the scan area for instructions. 2. Run the calibration wizard and follow the steps described in the section Scanner Calibration in this guide. 3. Be sure to choose Full Calibration. 1. Make sure that the Media setting matches the media loaded in the printer. If they are wrong, correct to the right media. 2. If you have used the correct Media setting in the Copy settings, you should recreate a new media profile: a) Thoroughly clean the scanning area. b) Run the calibration wizard and steps as described in the section Full Calibration in this guide. Be sure to choose full calibration. Now create a new Media profile: Entire image is not scanned c) Select -> Printer d) Select Media Profile to start the media profile wizard to create a new media profile. Follow the instructions on your screen. Make sure that you are loading the original correctly: 1. Be sure to align the center of the original with the scanner center arrow mark. 2. Load with the printed side face up. Page 12

13 Problem Large empty areas on both sides of the image One or more thin vertical lines (in the direction of paper feeding) show up in the scanned image, but not in the original document. Possible Causes and Remedies Go to the Area option in your scan settings before pressing the green go button. The All setting means that the scanner will disregard the original s size and capture the whole scanner width which will add white space on both sides of the document. Select Auto if you only want to scan the width of the loaded document. This is often caused by an unclean glass plate. Even a single spec of dirt in the wrong spot on the glass plate can cause a streak along your entire scan. To remedy: 1. Clean your glass plate and rollers as described in this users guide under Cleaning. 2. Most of the dirt on the glass plate comes from the documents that are passed against it. Wipe the document clean with a dry lint-free cloth before feeding the document into the scanner. 3. If the problem persists after cleaning, calibrate the scanner. The scanner may have memorized dirt specs and you will need to recalibrate after removing the dirt. 4. If the problem persists after cleaning and calibration Check the glass plate for scratches. A damaged glass plate should be replaced. Obtain a new glass plate from your service provider. Follow the steps in the user s guide to replace the glass plate with a new one. 5. A damaged calibration sheet can also cause streaks. Obtain a new sheet and recalibrate the scanner Page 13

14 3.4 Problems with the scan result Problem Whole image not scanned One or more thin vertical lines show up in the scanned image, but not in the original drawing. Possible Causes and Remedies 1. Check in your scanning application that your size settings are either for Auto detection or correspond to the size of the whole original. 2. Check that you are loading the original correctly from the scanner s right side. This is often caused by an unclean glass plate. Even a single spec of dirt in the wrong spot on the glass plate can apply a streak along your entire scan. To remedy: 1. Clean your glass plate as described in this users guide. 2. Most dirt on the glass plate is introduced by the documents. Wipe clean the document with a dry lint-free cloth before feeding the document into the scanner. 3. If the problem persists after cleaning, calibrate the scanner. The scanner may have memorized dirt specs and you need to recalibrate after dirt-removal. 4. If the problem persists after cleaning and calibration Check the glass plate for scratches. A damaged glass plate should be replaced. Contact your service provider for information. 5. A damaged calibration sheet can also cause streaks. Obtain a new sheet and recalibrate the scanner. Page 14

15 3.5 Troubleshooting Sequence This is a suggested Troubleshooting Sequence and will work in most cases. There are always some grey zones, especially if the problem is related to image quality. Page 15

16 3.6 Image Quality Problems Banding Problems. Bad/no grey balance calibration (CIS module to module match). Running WIDEsystem calibration should resolve this problem in most cases Crumpled Paper or folds Scanning originals that have folds or are crumpled on CIS scanners is often confused as a defect in the scanner, where it is actually a limitation of the technology used. Due to the very short distance from the sensor to the surface of the original, referred to as the Focal Length, if the document does not stay in contact with the glass plate then it is very likely to be out of focus. Page 16

17 3.6.3 Dust Problems. There are image quality problems that are not related to HW errors. These could be due to insufficient cleaning, bad calibration or limitations in the CIS technology. Streaks running in the scan direction could be caused by dust on the surface of the CIS module. Streaks that run in scan direction, that are color independent or a lighter shade of the color, are often related to the calibration. Check the calibration sheet for scratches, clean the glass plate and check the surface of the CIS for any dust before running the WIDEsystem calibration Stitching Problems. Typically, the scanner simply needs to be calibrated, either because the parameter block has been erased, the scanner has never been calibrated or the scanner has been moved around. If re-calibrating the scanner does not correct the stitching problem then check to be sure the document is lying flat against the glass. Stitching problem between 2 CIS modules. Page 17

116 7.4 CIS Focus Adjustment Make sure the latest version of WIDEsystem is installed onto a laptop for portability while working under the scanner. 1. To access the focus screws, you will need to be able to get underneath the scanner. It must be level, and in the operating position, so you must devise your own method of working underneath the scanner, making sure it is secure and stable, and not going to cause injury in anyway. 2. The image on the Focus Wizard when you run wide system, shows the order to adjust the focus. Remembering that the second screw is closest to the rear of the scanner. Page 116

117 3. The focus screws are difficult to see through the cut-outs, so a torch is recommended. One of the screws is located behind the spring, but still accessible if the screwdriver moves the spring aside. 4. For the initial adjustment, we must find the MAX value, or best focus. As the target is supposed to be 100% against the glass surface, we have to adjust the best possible focus to be exactly on the glass top surface. Page 117

118 5. As the height position of the MAX focus point is not very precise, due to the flat focus curve, we go back (80%) to where the focus, or MTF* curve, has a steeper angle. 6. From this point, we go forward a distance of 150o turn of the screw, this brings the theoretical peak focus a little above the glass surface. This means we can get as much of the flat curve focus to be above the glass surface as possible. Page 118

119 7. Open the top plate, and remove the hold down plate. 8. Place the calibration target centrally face down on the glass, with the arrow towards the measurement label. Page 119

120 9. Place the hold down plate on the top, making sure not to move the target, and that the target and plate are flat on the glass. 10. With the scanner raised off the surface, remove the plastic covers from the alignment cut outs. Page 120

121 11. Open wide system, and click the icon in the top corner. Click service, and enter the password xetnoc. 12. Open the focus adjustment wizard. Page 121

122 13. Starting with CIS A-1, locate the adjustment screw, using a torch if necessary. 14. Turn the T9 screwdriver until the 'Max' value and the Now! value are the same, or as close as possible. Page 122

123 15. Then move onto the next step, and reduce that value down to 80%, following the direction that is indicated on the wizard. 16. Then the 3rd step of returning the screw back by 150 degrees, as indicated on the wizard. Page 123

124 17. Any small amounts of red should be solved by adjusting the other end of the CIS. If not, go back and repeat the alignment again. 18. Repeat this process for the other end of the CIS. Page 124

125 19. The wizard will do a final check at the end. If any are still out, as shown for CIS-C. Then start again and make adjustments. 20. Refit all the plastic covers. Page 125

126 21. Refit the Hold Down Plate back into the Lid. 22. Move the scanner back to its operating location when this process is complete. 23. Run a Full Calibration. Page 126

127 7.5 Full Calibration 1. Before calibrating, make sure the Glass Plate is clean. 2. Correctly insert the calibration target onto the scanner with the targets arrow pointing towards the left. Page 127

128 1. On the scanner touchscreen, use your finger to move the icon to the Setup icon. 2. Using your finger, move the icon to the Setup icon, and then choose Scanner. Page 128

129 3. Click Calibration. 4. Click Full Calibration. The Calibration will take about 27 minutes. Remove the target when completed. Page 129

130 8 Scanner Terms Activation Code: Is when the product specific License code has been paired with a Scanner serial no. Adaptive Thresholding: Advanced 2-D Adaptive Thresholding estimates the background grey level in a window area around each pixel. The difference between the actual pixel value and the background is then compared to the adaptive settings to determine if a pixel is thresholded as a black or a white pixel. Additive Colors: The additive primary colors are red, green and blue. These additive primaries represent the three main components of white light. Used individually or together, these three colors of light can be mixed to create nearly all colors. When these three primary colors are mixed in equal parts they produce white. Additive color is used in scanners and computer displays. ADL+ Error Diffusion Half-toning: Image Processing that supports visibility of greytones in printed output by adding toned shades of grey in regions between black and white. Carried out as a segment of Dual 2D-Adaptive enhancement processing in copy modes. ALE - Accuracy Lens Enhancement: Accuracy Lens Enhancement (ALE) is an electronic correction of spherical errors in CCD based camera- scanning systems.when looking at pixels across the range of a camera, the pixels tend to be more elliptical at the outside edges of the lens and more round in the middle of the lens. This anomaly is known as a spherical lens error and can introduce inaccuracies in the scanning system that can vary quite substantially between different points along the scan line. Most manufactures typically state a +-0.1% accuracy of the scanner between the two outermost end-points of the scan line. However, when measuring between two points that do not fall across the entire scan line, it is not unusual to see variations of up to % or even higher. This is naturally unacceptable in demanding environments and markets such as GIS, which need a stable and well-defined maximum error of 0.1% or less. ALE solves this problem by a process to electronically correct the spherical errors in the scanner and maintain a stable maximum error across any two points of less than 0.05% ± 1 pixel. ATAC: Automatic Thickness Adjustment Control - A special technology that allows the scanner pressure platen to be raised to accommodate thick originals and then lowered - both actions performed by pressing a key from the operators panel. Sensors in the platen detect when perfect pressure is applied to the the original and automatically stop the downwards motion of the platen so it rests on the original with an optimal grip. Bitmap: An image format made from a matrix of individual pixels (.bmp). Page 130

131 Bitmapped Image: A bitmapped image is a computer file representing a line-art image that was scanned with a scanner. Refers to the pattern (map) of bits that are either black or white. Black Level: The Black Level is a setting in scan programs used to change dark greytone colors to true black. For example, if one is copying a brochure with a mixture of text and pictures, the text will often be digitized to a color that we may see as black but really is a dark greytone. When the printer digests this greytone data, it will print the original s text with a halftone pattern, meaning scattered dots instead of solid black. By increasing the Black Level value, one can get the text to be copied in real black and it will therefore appear clearer. Black Point Adjustment: An adjustment made that will determine the amount of shadow detail in an image. It is considered proper to set the black point so that the darkest part of an image will only just have zero detail. Blueprint: A process of photographic printing used mainly for copying architectural and mechanical drawings; produces blue lines on a white/bluish background. Blur: The averaging of pixel elements. Brightness Adjustment: An adjustment on a scanner that allows the user to compensate for a light or dark original. Calibration: Adjusting a device so that it performs in accordance with an established standard. Scanner calibration is minimizing color deviation between scanned ANSI IT8 reference color patches and the known color reference values. Generally, Calibration is the process of setting a device to known color conditions - stabilizing the device to a known and quantifiable state. Calibration is commonly done with devices that change color frequently, such as monitors (phosphors lose brightness over time), scanners (light changes) and printers (proofers and other digital printing devices can change output when colorant or paper stock is changed). CALS: Computer-aided Acquisition and Logistics Support (CALS) standard, a U.S. Defence Department and industry initiative that addresses the design, manufacture, and support issues of generation, access, management, and use of technical data in digital form. CCD: Charge Coupled Device, CCD is the image sensor in the scanner that converts light to voltages. These voltages are converted by the scanner into the image. CCITT Group3: Standard run-length compression format used with FAX transmission. It utilizes modified Huffman coding to further compress the run-length numbers. Most scanner file formats are dialects of this format. Page 131

132 CCITT Group4: Two-dimensional compression format, giving very compact image files. Standardized by CALS (MIL 28002) and ISO- ODA for Drawing Archival and Interchange. CIE LAB: A device-independent color space specified by CIE, used in modern color management software to facilitate conversion of data from a scanner to a display, or from a display to an output device. CIE: Centre Internationale d Eclairage (CIE) is an international organization that establishes methods for measuring color. These color standards for colormetric measurements are internationally accepted specifications that define color values mathematically. The first color space model, the CIE xyz, was developed in CIE defines color as a combination of three axes: x, y,and z. The two color spaces released in 1978 are CIE Lab and CIE Luv. The goal was to provide an accurate and uniform reference of visual perception. CMYK: The subtractive printing colors. Cyan, Magenta, Yellow, Black. Color Balance: The visual effect of an image when the amount of each color and the overall amount of color are balanced. Color bit depth: The simplest pixel has two options: black or white. (A pixel with two choices is known as a 1-bit image, or two raised to the power of one). Adding more bit information increases the number of color options. The number of potential color options for a pixel is called color bit depth. For example a 4-bit pixel would have 16 color options, and an 8-bit pixel would have 256 color options, while a 24-bit pixel would have 16,777,216 color options. Color Cast: An image is said to have a color cast if its colors are not true. A color cast will usually be described by stating the particular color predominant in the image, e.g., the grass appears to have a red color cast. Color Correction: To improve the color rendition. Correcting for, and eliminating an unwanted color cast. Color Management System: Color Management System (CMS) software increases the accuracy of color interchange between scanners, displays and printers based on profiles for each device. The CMS is a layer of software resident on the computer that negotiates color reproduction between the application and color devices. The CMS performs the color transformations necessary to exchange accurate color between diverse devices. The Color manager needs access to characterization data for the device. The format and content of such device profiles is standardized by the International Color Consortium (ICC.) Page 132

133 Color Separation: Process of separating colors, in an image, into primary color components for printing. Converting an RGB color image into CMYK color image. Color separation is a technical function during which critical settings such as GCR, black ink limit and total ink limit are applied to the image. Color Space: A color space is a particular language used to describe color. Examples of color spaces are: RGB, CMYK, HSV, CIE LAB. Contrast: The difference between the lightest and darkest significant areas in a picture. A picture with high contrast has nearly white areas and nearly black areas with sharp changes in brightness between them. The picture seems dominated by stark light and dark tones. Density units: Photographers and printers measure transmission in base-10 logarithmic density units, where transmission of unity corresponds to a density of 0, transmission of 0.1 corresponds to a density of 1, transmission of 0.01 corresponds to a density of 2, and so on. Density: The light stopping ability of a film. Density is inversely proportional to the amount of light reflected or transmitted by an image. Device Dependent Color Space: For example RGB. A device dependent color space, e.g., the same scan file will appear different when viewed on different computer displays. For example CIE LAB. A device independent color space is one in which color values are absolute, e.g., defined by CIE standard. CIE LAB is the central color space in color management systems (CMS) and is used to translate between different device dependent color spaces such as scanner RGB and display RGB. Device Profile: A file used as part of a Color Management System (CMS). A device profile contains information about the characteristics of a scanner, computer display or printer. The format for device profiles (Win95, Colorsync. etc.) is standardized by ICC (International Color Consortium). DIP: Digital Image Processor. Hardware embedded function that does image enhancement in real-time while scanning. Dither: To use patterns of different colored pixels to create blended colors; or, to use dots of different sizes to simulate greyscale images. (see below). Page 133

134 Dithering: A printing or display device may have only a small number of greyscale or color values for each device pixel. However, if the viewer is sufficiently distant from the printed page or display, the value of neighboring pixels can be set so that the viewer s eye integrates several pixels to achieve an apparent improvement in the number of levels or colors that can be reproduced. Dots Per Inch (dpi): A measure of dots in a square inch where the individual element is a round dot on the printed page. DPI: Dots Per Inch, equivalent to Pixels Per Inch. An expression of resolution of a scanned image. DSP: Digital Signal Processor, does image enhancement in real-time while scanning. Dual 2D-Adaptive Enhancement: Enhancement processing on the foreground and background separately. Processing is performed on-the-fly. The separate enhancement processes are simultaneously performed on different drawing aspects. Dynamic Range: A measurement of scanner quality; the density difference between highlights and shadows. Edit: Modify an entry using standard Windows text-editing techniques. Emulsion: The light sensitive silver, coated on the clear acetate film base, that forms the photograph when a picture is taken and the film is developed. Equalizing: Distributing all color or tone equally along a density range. File Format (image): The format in which a scanned picture is saved. Many programs can insert or import a picture from a file, if it is saved in a file format that the program supports. Common file formats include TIFF (Tagged Image File Format), BMP (Windows bitmap), JPEG (Joint Photograph Expert Group), and FPX (FlashPix format). Flip Horizontal: To flip the picture left/right. Foreground: Foreground when scanning raster data (black and white, or monochrome data) refers to the pixels that represent data of interest (background refers to everything else). Typically, lines and shapes are represented by black pixels (foreground) and empty space is represented by white pixels (background). When scanning greyscale data, background means the grey level of a region of pixels that surrounds some desired foreground data. Page 134

135 Gamma Adjustment: An adjustment that makes the tone distribution lighter or darker in an image. Gamut Transformation: Color Management System function, where out-of-gamut colors are converted to colors within the gamut of the targeted device, e.g., a printer. Gamut: The color range scanable, printable or displayable by a device; e.g., if some of the displayable colors are outside of the gamut of the printer they cannot be printed. GCR: Grey component replacement. A color separation setting used on color photographs where cyan, magenta and yellow inks are replaced by black ink (in a balance that would yield a grey value). The advantages are a reduction in overall ink usage and some increase in image detail. Greyscale: A term for a black and white photographic image or a scanner setting. Refers to the range of 256 greytones that make up the image. Half-toning: The processes of offset printing and laser printing are intrinsically bi-level. However, these devices can reproduce a range of tone levels by halftoning; e.g., an array of widely spaced dots produces the perception of light grey, and an array of tightly spaced dots produces dark grey. Halftone dots are usually placed in a regular grid. In color printing it is conventional to use cyan, magenta, yellow and black grids that have exactly the same dot pitch but different carefullychosen screen angles. Hardware id: Is a unique ID no for the scanner, based on the scanners serial no and MAC address. Highlights: The lightest part of a picture reproduced as white on the screen or when printed. Histogram: A bar graph representing the statistical distribution of Greytones or colors in an image. Each column represents the number of pixels at that grey level or color. HLS: A color space with the three variables of Hue, Lightness, Saturation. See HSV. Page 135
