Pls check your color Scan settings. Generally there will be some color difference between the original and scanned Image because, the original is 'reflected light' whereas, the scanned image is a 'source light' on the monitor. The monitor setting can also affect the color output. S. Mohan

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.

Scanner image is askew


Base on your explainination it seems like, this is because of your setting in MP Navigator, the image may not be scanned properly. In such a case, it is necessary to match the settings in MP Navigator to the document. please do the following. 1) Match the type of the document on the platen glass to the document type set in MP Navigator. For example, when scanning a color photo, select Color Photo in Document Type of MP Navigator. 2) Match the size of the document on the platen glass to the document size in MP Navigator. For example, when the document size is A4, select A4 in Document Size of MP Navigator. (Memo) Auto Detect is set in Document Size as the default.

How to have white background on small documents


All areas outside of the document will be black only. I don't know how you were getting white background.
If you want white background around your scanned image, a) stick the check (in this example) onto a white paper and scan the whole sheet. Ensure double detection is off. b) You can also do this in software, by cropping a larger area outside the scanned image.

There are many options to view the scanned image like Actual size or Fit or Fit vertically or Fit width. The same image will appear different in each case.

Have long experince with PixEdit program using Kodaks. PixEdit usually comes around it after a firmware upgrade on the scanner. Not sure about this specific model but at least OK on other models of Kodak.

Scanned Items or Copies all print in Solid Black


I assume that you mean color images are being produced in black and white. If that's the case, there's a document on the HP web site that shows you what to look for and provides solutions:

Color Image Prints in Black and White

Good luck.

Scanned image only prints in black and white


it's tricky / annoying:

you have a preview ...
you have some of the (3) images checked
but also you have some of these images selected (blue outline)

now:
when you select (I don't mean the checking) an image you'll have to set the scanning params
again - or check them ...

if you select an image, and then set the params (like "color"), your scanned image will be in color

....
also resolution is the same way ..
especially after crating preview .. it'll be set to 300 Dpi
so after seecting one for scanning - check the resolution too :)
