Recommended Resolutions to Suit Your Purpose

Resolution indicates the number of pixels (smallest area of an image) for each inch (25.4 mm), and is measured in
dpi (dots per inch). The advantage of increasing the resolution is that the details in the image become fine.
However, it can also have the following disadvantages.
❏ The file size becomes large
(When you double the resolution, the file size becomes about four times larger.)
❏ Scanning, saving, and reading the image takes a long time
❏ Sending and receiving emails or faxes takes a long time
❏ The image becomes too large to fit the display or print on the paper
See the table and set the appropriate resolution for the purpose of your scanned image.

Scanning Originals to a Computer

There are two methods of scanning originals to a computer; scanning using the printer's control panel, and
scanning from the computer.
A file format that allows you to compress the data to be saved. If the compression ratio
is high, the image quality declines, and you cannot convert the image back to the
original quality.
This is the standard image format for digital cameras. This format is suitable for images
that have many colors.
A general file format that can be used across different operating systems and provides
the same level of screen display and print result.
Also, you can save the multiple pages as a one file.
You can view PDF files using dedicated PDF reading software or in Web browsers.
