If you have your scanner set to "text/photo", or anything other than just 'text", the visual quality will come out lite in appearance.

Hope this helps. :)

I have used last 4 year canon 2900B printer. How to set 300 dpi printing resoluation


Canon PIXMA Manuals MG2900 series Resolution
Resolution The data in the image you have scanned is a collection of dots carrying information about brightness and color. The density of these dots is called "resolution", and resolution will determine the amount of detail your image contains. The unit of resolution is dots per inch (dpi). Dpi is the number of dots per inch (2.5 cm). The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less detail.

How to Set the Resolution You can set the resolution in Resolution on the (Scanning from a Computer) tab of the Settings dialog.
Appropriate Resolution Settings Set the resolution according to the use of the scanned image.
Item Type Use Color Mode Appropriate Resolution Color photo Copying
(Printing) Color 300 dpi Creating a postcard Color 300 dpi Saving to a computer Color 300 dpi Using on a website or attaching to e-mail Color 150 dpi Black and white photo Saving to a computer Grayscale 300 dpi Using on a website or attaching to e-mail Grayscale 150 dpi Text document (document or magazine) Copying Color, Grayscale, or Black and White 300 dpi Attaching to e-mail Color, Grayscale, or Black and White 150 dpi Scanning text using OCR Color or Grayscale 300 dpi Important
  • If you double the resolution, the data size of the scanned image quadruples. If the file is too large, the processing speed will slow down significantly, and you will experience inconvenience such as lack of memory. Set the minimum required resolution according to the use of the image.
Note
  • When you will be printing the scanned image by enlarging it, scan by setting a higher resolution than the recommended one above.

When scanning with the native scanning software, the scanner runs very fast but file size is huge. When I use Adobe 9 to scan, my files size is much smaller but the scanner pauses after each page. I need...


I would expect the problem with the Capture perfect fike size is down to the compression chosen for the output file. Ideally black and white inahes should be Group 4 TIFFs and Colour or Greyscale should be JPEG. Alternatively you may want to check the scanner is set to 'scan ahead' in the twain settings in Acrobat. If it is set to anything else the scanner will slow down to allow the PC to process every image. With 'Scan Ahead' turned on the scanners memeory buffer the PC speed a little giving you faster scanning.

How can I scan a document then print it with larger print?


You can scan a document or photo or negative film etc.. using a scanner, there a many types of scanners which you can choose as per your requirement. There are dedicated scanners, all in one integrated scanners, or two in one like that.. but if you need it for your professional use or daily use, it's better to get a dedicated scanner not "all in one" since with all in one if the copier fails or fax fails, the scanner will also fail because they are related and built-in integrated.
The process of scanning a document is as follows;
  • > Place the document on the scanner's flatbed.
  • > Press scan button or scan using the integrated software from the computer.
  • > Customize the scan settings/quality.
  • > Save the scanned documents.
Printing a document to a larger size is different, you can use photo editors like photoshop, paint.net etc..where you can changed the resolution as well as the size of the image. It's best to change the size or resolution before you give the print command. Or you can also change the print size with the paper size or print size.
If you still need more help, please let me know with more details. I am ready to assist you.

Good luck.

Thanks for using FixYa.

Xerox Documate 152 - Scan quality is now V.BAD!


I would go to Xerox.com and look up their knowledge base. Here is a copy of data from their site related to this problem:

Symptom: Scanned images have poor image quality, are fuzzy, unclear, or hard to read.
Cause: There are several things that can lead to poor image quality including the scan settings, dirt on the scanner, and driver problems. Solution: Note: If you scan as a PDF file and your scans look fuzzy when viewed in PaperPort, try right clicking on the file and selecting "Open" to open them in Adobe Reader. If they display fine in Adobe Reader then there is nothing wrong with the scans, it is simply that they are not being displayed well in PaperPort.

The following solutions can help resolve poor scan quality.

Solution 1 - Adjust the scan settings

Try increasing the resolution of your scan. 300 dpi to 400 dpi should be clear for most images
  • If you are scanning in Black and White, try Grayscale or Color. Some images will not display correctly in Black and White
  • You can also try adjusting the brightness and contrast
  • Note: For information on adjusting your scan settings, refer to the user guide for your scanner
Solution 2 - Clean and Calibrate the scanner

Note: Calibration only applies to sheetfed scanners.

Use the link below for instructions on cleaning and calibrating (if applicable) your scanner:
Solution 3 - Reinstall the scanner driver Select a link below for instructions on reinstalling your scanner driver:

Fi-5750C Fujitsu scanner can't change grayscale default setting


Photoshop is not an "advanced" scanning program. To get some "production" and value out of this expensive scanner you need a professional scanning program which also may control the settings of the scanner. Use PixEdit which utilizes the built-in jpeg compression in the scanner. Did a test scanning 10 pages A4 duplex fullcolor. Adobe Acrobat Pro used 4 minutes. PixEdit used 20 seconds. Guess Photoshop (in your version) would also scan uncompressed and not use this good scanner optimal.

Scanned documents are very light


I have found that when scanning b/w documents, its helpful to start with a black and white copy, not a grayscale, pen written, or printed form a printer in grayscale mode copy, but a true black and white on the copier or fax copy. The scanner doesnt read shades of black so well and when scanning multiple page documents, my pixma tends to scan in lightly. I havent found a piece of software to do just this, batch darken what has been scanned (at least not for free). Copying before scanning is the work around. Hope this helps everyone who's had this problem. It also doesnt hurt to darken what your scanning down a notch when copying

Gray backround


Does your scanner software give the option to choose different modes...grayscale, color, black & white?? This sounds like it's scanning in grayscale....if you can change it to black & white, the background should remain white.

Scanning speed problem


The scanners rated speed is for black and white all error correction turned off. As soon as you start doing 24bit colour or grayscale or up the dpi the scanner will start scanning more slowly. I personally get abpout 60ppm with my error correction on black and white 200dpi. (300 dpi scans just as fast although 400dpi will slow down).
