Image resolution
This printer can print out images in the image resolution of 600 × 600 dpi and also in the Fast1200 mode that provides
the image resolution with finer density. The Fast1200 mode outputs the further microscopic dots and improves the
resolution, and furthermore it is possible to express the halftone in addition to depicture the monochrome images by
controlling the irradiation time of laser light.

Principle
Smoothing (KIR)
The printer applies the KIR (Kyocera Image Refinement) to the smoothing processing, which is the exclusive image
processing technology developed by Kyocera Mita Corporation. This function corrects the jaggy part of image (jagged
lines) on slant lines or curves, which is easy to notice, to the smooth line by embedding small dots.
A
: The electric potential of
dot is attracted and these
corrective dots are positioned
on the image due to the
effect by the peripheral black
dots.
