Reference
The five screens are provided with five screen types for each as mentioned above, and a specific type can
be selected for each screen. The screen type is predetermined by the administrator. If setting change is de-
sired, consult your administrator. For details, see Section 9 of the User's Guide - Main Body.
How to reproduce copy images
The line screen uses many halftone lines, like scanning lines of a television, and provides fine quality in re-
producing the gradation in images. However, text originals may not be reproduced clearly in this method,
being processed in the same way as photo originals.
The dot screen uses dots to reproduce an image.
The Stochastic is an error diffusion method that uses aperiodic small dots to reproduce copy images. This
method is suitable for reproducing text originals sharply.
