Why do scanned documents appear unclear in PDF format?


Perhaps you're scanning at too low resolution? If you want images to be clear at normal size, scan at 300 pixels per inch. Your scanner may be scanning at fax resolution, 100 by 200 pixels per inch.

I HAVE A BLACK LINE ON ALL MY SCANNED COPIES , EVEN ON PLAIN COPIERPAPER. PLEASE ADVISE


There are two possibilities: 1) The scanner sensor has a dead pixel, or 2) There is a particle covering a pixel of the linear scanning sensor array.

If you are up to it, open the scanner carefully and clean all the optics while you are at it. So the back of the glass cover, the mirrors (carefully!) and then the sensor. You may want to use a duster spray can (I think Office Max or Depot carry those) and dust of the sensor and the mirrors instead of using a soft cloth. If the scanner uses first surface mirrors, then one can very easily ruin the mirror coatings and it will be full of scratches from the dust particles when you wipe them! If they use regular mirrors (where the reflective coating is behind the glass) then it is safe to use a cloth.

If that does not get rid of the black line, then you have a dead pixel in your scanner sensor and you need to buy a new one.

There may be a way to tell whether it is a dead pixel or a dirt particle on the sensor. If you open your scanned image (or plain white paper image), magnify the image and see if the line is exactly one pixel wide - that would point to a dead pixel. If it is more than one pixel wide and the scanner did not do an interpolation then it is a dirty sensor. To make sure, scan with the maximum intrinsic resolution (chek the scanner's manual for that), so you don't interpolate between pixels. I am still not sure if that also applies to color scanners, they have a color filter over the linear detector array. It may depend on how the pixels for the color coding are arranged. But then I would expect an 'off-color' line, not a black line. If it is a black line and if it is more than one pixel wide, I am sure that a dust particle is the reason for it.

Good luck, Stephan

UNABLE TO MAKE CORRECTIONS TO DOCUMENT


Scanners put a graphic image on your computer that is a "picture" as far as the computer is concerned and therefore, you cannot edit text because it is seen as pixels and not characters. In order to make a scanned document editable, you'll need to use the OCR function in your software (Optical Character Recognition). This is assuming your printer came with OCR software, if not, you'll need to purchase an OCR software package in order to convert images into editable documents. You should be able to find such packages for less than $50.00. Check your documentation (and help files) and look for OCR in the index or search the help files for OCR to see if such software came with your printer software package.

I scanned a document, but when I go to attach the file, it stays in attaching files forever??


Greg, Do you mean that when you want to send it by email it keeps attaching the file forever? If yes then check the size of the scanned document. What happens is that the moment you attach a document to an email Windows start sending it to the email server and that takes time as uploading is slower than downloading. And if the file a large one as scanned documents can be, then it will take that much longer. Try a smaller document first. Size wise small document. If that works fine then you can try larger documents. yes it may be time consuming but there is no price for mental satisfaction. To reduce the size of the scanned document, reduce the pixels in settings of the scanner. or reduce the page size. You will find the document reduced many times over.

Need to get scanned photos to between 300 and 600 dpi


What I saw first off is that although the resolution indicates 96 DPI, the file size itself between the 2 examples are drastically different. You are putting raster images into MS Word for publication work, and that is a NO NO. Word was not created for any kind of high resolution printing. It's a glorified text editor that people seem to think is an option for printing. YOU WILL NEVER GET 300 or 600 DPI images out of Word. Ever.
To create your project for printing, you need to use software more suited for the task. InDesign and Quark are examples, but they are very expensive. In my opinion, Publisher would be better for this kind of project and I hate myself for saying that.
Talk to your Printer, find out his specifications for Applications and Linescreen for Printing. The minimum requirement is 280 DPI, but if the image is placed at 100%, 600 DPI is overkill.
Oh, and try to never scan a scan... you are looking for trouble... a little thing called a Moiré pattern comes into play, and it will make you images print NASTY!
I could go on about your post all day long, but if there is anything else I didn't explain, please post again.

A scanned document is an image file. As for an image doesn't allow tekst editing like an application such as Word does, you'll need OCR software.(Optical Character Recognition). This software is intelligent enought to read character instead of pixels.

Here's an overview of OCR Software:
