Need a sharper scan. What's the difference between resolution (DPI) and compression? Need to send a 9-page document with color pix and B&W copy that's clear but doesn't take 20 minutes to download. Can you help me a little? (I've got a windows PC and an Epson CX6000.)

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.

alot of the time if you scan something it will streach the image because of the scanner resolution. check you setting on the printer. you might need to change the settings to stop it from doing that to make he image more clear. if that doesn't work than also some printers are just like that when you scan something. it will also make one page turn into two pages. that may just be the way the printer is.

change print grey scale to 2 color.

1. Turn on your all-in-one printer and computer. Check the connections between the two machines.

2. Lift the printer's document lid. Examine the scanning surface and the underside of the lid for dust and fingerprints.

3. Put the document you wish to scan face-down on the glass. Use the alignment markers to help you square up the object. These are usually found on the left-hand edge of the scanning area.

4.Close the printer's document lid slowly so the document does not shift position.

5. Select a scan resolution. The higher the dpi (dots per inch) count, the sharper and more detailed the image.

6. Push the scan button. You may have to do this on the printer itself or on your computer.

7. Check the preview of your scan on your computer. Depending on your all-in-one printer and software, you may have to prompt your computer to display the preview for you.

8. Edit the image as it appears on your computer if you want to make changes. Your scanning software might let you enlarge, resize or otherwise manipulate the final product.

9. Accept the scan and save. Return the original document to a safe location.

Adjusting the Scan Contrast or the Image Quality (Fax Resolution)
Adjusting the Scan Contrast

Resolution and color depth are the 2 main factors that determine the size.
Scan in black & white, and reduce the resolution to 150 dpi, that should give you very small PDFs.

I scan text pages at 30kb with my HP 5610 in PDF.

No, it's an ink jet printer
