Scanning Problems I am suddenly getting black lines in place of text when I scan a document. Can you help?

    cmdina1,



    Thank you for your quick response. the lines are horizontal and appear on the screen after I have scanned a document. There is some text, but it is "iterrupted" by the horizontal lines. The printer/copier works fine.



    I did some playing around and discovered that when I save the scan as a file OTHER THAN .pdf, It looks fine. I have not tried printing the .pdf files since they appear illegible on the screen.



    Thanks -

I need some more information are the lines horizontal or vertical? Does it print fine from the computer? Does this problem only happen when you scan an item in and then print it or copying an item then print it? Also when you get this output do you have some of the text and lines or just lines?

    It sounds like you need to upgrade your version of adobe. It is not a printer problem or a scanner problem. Let me know what ver of adobe you are using by going to the help on the program and then about . This will give you the version ex. Adober reader ver 8.1.0

I am scanning a photo. I have translucent lines running horizontal through the picture before i print it.


Documents scanned/copied from the document feeder pass over a thin glass area where scanning occurs. Clean this area if sent faxes, copies or scans have black or white vertical lines.
  1. Lift the document cover to expose the platen glass.

  2. Wipe the ADF scan area (C) with a clean, soft, lint-free cloth moistened with water.

  3. Then wipe with a clean, soft, dry, lint-free cloth making sure there are no residues left, especially on the platen glass.

  4. Close the document cover and make a copy of a text document to confirm the black line has disappeared.

I am trying to scan a document and it is not working, I have a hp photosmart c4280 printer. How do I install a usb cord


hi
Place the document or image into the scanner for scanning. A scanner with a paper feeder will only receive flat papers and photographs, but a flatbed scanner opens to accommodate books, fabrics and leaves along with flat papers. There is even a attachment for feeding photo slides into flatbed scanners.
  • Step 2 Start the scanning softwaremag-glass_10x10.gif. If the scanner does not engage the software automatically, press the "start" or "scan" button, or click the scanner icon on the computer screen to initialize the software.
  • Step 3 Activate the scan. Click the "file" menu and select "acquire," "import," or another practical choice that applies.
  • Step 4 Preview the item to be scanned. Most scanners have a preview option. This will show the scan area inside dotted lines. The lines can be moved with the mouse to relocate, enlarge or crop the scanning area.
  • Step 5 Set the resolution for images by number of dots per inch (dpi). For computer screen viewing, 100 dpi should suffice. Use 200 to 300 dpi for items to be printed.
  • Step 6 Use the appropriate setting for scanning black and white text. If the scanner does not show a preset for text, use "line art" or "black and white" at 300 dpi. Then use the optical character recognition (OCR) program to convert the image of the text into a file for word processi

    I'm having trouble scanning B&W documents with my Epson V300. The edges of the letters in the text are jagged and hard to read and there is what appears to be a crease or fold in the document when the...


    You have two options for scanning text. You may explore both of them and see which is better for you. Either way, you will have to make friends with manually changing the scanning settings, because simple presets often are not suited for every case.

    First is to use Grayscale mode, and a minimum resolution of 200dpi. This should give you satisfactory text quality. If you want to print the text afterwards, 300dpi would be even better. You may want to increase contrast, to get the letters more defined and eliminate most of the background toning.

    Second is to use Black and White (monochrome) mode, but in this case you need to set the resolution higher, preferrably to 600dpi. Also in this case you will have to play with the Black/White threshold in order to eliminate background "dirt" appearing as black artefacts.

    If you scan the documents in order to process them with OCR software, usually the OCR application will give you suggestions on how to set the scanning parameters to obtain good results.

    How to scan picture to upload on computer


    First, ensure you are connecting the scanner to your computer. I'm assuming USB connection, and that you're using an operating system supported by this device.

    Next, install the drivers and software for this device. Those should have come with an installation disc, but if you don't have that disc, you can get them from the PIXMA MP830 support site, here:
    http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=123&modelid=12804

    To scan a single document, place the document:

      1. Alternatively, on the Windows taskbar, click 'Start', point to '(All) Programs', 'Canon', then 'MP Navigator 2.2'.

    Canon D860 - I get a solid black line when I use paper feeder.


    I'm pretty sure you might have solved this problem already, but this might help others.

    Make sure that the platen glass is clean near the right side of the machine, where the document is scanned when going through the document scanner. Remember, when placing a document on the glass to copy it that way, you would place it on the glass on the left side of the machine. When scanning through the ADF, the scanning unit itself moves to the right side of glass and scans the document as it moves through.

    We had the same issue and found out that there was a little spec of dirt on the glass. After cleaning it, the problem was solved.

    We have a canon MP610 printer scanner combo, I work in a dentist office and am trying to scan a x-ray. When I do it is'nt picking up the detail very well at all. I think I need to adjust the settings but I...


    the only way to get a little more detail out of this printer with x-rays is to INCREASE the DPI resolution. there are no other adjustments that are abailable.
    The Scan Settings dialog box opens when you click Specify... on the Scan/Import Documents or images screen.
    The Scan Settings dialog box allows you to specify advanced settings for scanning.

    Document Type
    Select the type of document to be scanned. To scan photographs, select either Color Photo or Black and White Photo. To scan text documents, select either Color Document, Black and White Document, or Text(OCR). To scan magazines, select Magazine(Color).
    Document Size
    Select the size of document to be scanned.
    Auto Detect: Detects document size automatically.
    Auto Detect(Multiple Documents): Select this when scanning multiple documents at one time.
    Select Stitch-assist to scan the left and right halves of a document separately and combine them back into one image.
    Reference See the section below for details.
    Scanning images Larger than the Platen (Stitch Assist)
    When you select Custom, a dialog box in which you can specify the document size opens. Select a Unit, then enter the Width and Height and click OK.

    Important When you select Auto Detect the position or size of the image may not be scanned correctly depending on the document. In such a case, specify the document size, such as A4 or Letter according to the document to be scanned, and align a corner of the document with the corner at the arrow of the platen.
    When you select Auto Detect(Multiple Documents) allow 3/8 inches (1 cm) or more space between the edges of the platen and the document.
    If not, some images may not be scanned at the correct positions and sizes.
    You cannot select Auto Detect(Multiple Documents) or Auto Detect when Document Type is Text(OCR).
    Scanning Resolution<<<<-------------------------------------------------------------<<<<<<<<<<
    Select the resolution at which to scan documents. The following scanning resolution can be specified:
    Text(OCR): 300dpi, 400dpi
    Others: 75dpi, 100dpi, 150dpi, 200dpi, 300dpi, 400dpi, 600dpi
    The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less detail. At high resolution, scanning takes longer and file size becomes larger than usual. See the section below for details on resolution.
    this should answer your question , feel free to post here agian if you need more help.
