Selecting The Right Resolution; Using The Scanner In Other Applications - Sharp UX-4000M - UX 4000 B/W Laser Printer Service Manual

Selecting the Right Resolution

The higher the resolution, the more detail a scanned image will have. However, you
should always keep in mind the use to which the image will be put. An image that is
scanned at maximum resolution when there is no real need to do so simply takes up
valuable disk space. Your hard disk can quickly become filled with needlessly large
high-resolution images, which take much longer to print.
In general, photographic images, particularly landscapes, can be scanned at lower
resolution, because even the large pixels of a low-resolution scan are not very
noticeable. Such images also tend to be very large when scanned at high resolution.
On the other hand, text, logos, diagrams and line art originals should be scanned at the
highest possible resolution. With these kinds of images, jagged edges are much more
visible.

Using the Scanner in Other Applications

You can use the unit to scan in any application that is TWAIN compatible. TWAIN is a
cross-platform interface that allows scanners to be controlled from within compatible
applications. You can scan images directly into many of your favorite graphics and
image manipulation software, such as Adobe
how to use the TWAIN driver with these applications, refer to their user's manuals.
