Reproducing Images

This machine provides two methods for reproducing images.
The Dither (Error Diffusion) method uses small dots (600 dots per inch) to reproduce
the image. This method is appropriate for text originals.
The Screen method also provides two methods, Line Screen and Dot Screen. The
Line Screen uses many halftone lines, like scanning lines of a television, while Dot
Screen uses small dots to reproduce the image. The Screen methods provide fine
quality in reproducing the gradation in scanned photographic images, however, text
originals may not be reproduced clearly by using the same method as photo
originals.
