The EPSON Perfection 1200S’s maximum hardware resolution of 1200

×

2400 dpi is

achieved through EPSON’s advanced Micro Step Drive technology. This technology

enables the EPSON Perfection 1200S to achieve a maximum sub-scan or vertical

resolution of 1200 dpi or 2400 dpi using “half-stepping” of the scanning carriage to

double the optical resolution.

Scaling (Resizing) Images

If you plan to enlarge your image, it is better to enlarge it when you’re scanning rather

than in your application. Each time you modify an image, you lose some quality.
Keep in mind when you enlarge a small photo, such as a 35 mm slide or wallet-size

photo, you’ll need to scan at a high enough resolution to retain your image quality,

but not so high that your file size is too large to be efficient.
You must manually adjust the resolution (dpi) to maintain the same image quality

when you resize your image. For example, if you have a 300 dpi 2

4 (a factor of 200%), increase the Scale setting to 200%

and change the resolution to 600 dpi.

One-Touch Scanning

Your EPSON Perfection 1200S features a one-touch scanning button. With

one-touch scanning, you can just load a document in the scanner, press the scanner’s

]Start button, and then PageManager opens EPSON TWAIN automatically. To use

this option, you must first install Presto! PageManager (or another application that

supports linking to scanner events with the Start button on Windows 98) and enable

the scanner monitor utility. For details on how to set up one-touch scanning, see

“Using the Start Button” on page 29.
