 Explanation
Variation in density may appear on images depending on date and time when copying or printing is
performed or the type of a job. To maintain image quality at a certain level, the types or the intervals
among image quality controls must be adjusted.
There are two image quality control modes; the Short Mode which is only for adjusting density on solid
images in a short time, and the Full Mode which is for adjusting density on the wide areas from Low/
Middle density to solid images.
 Procedures
The service technician must perform the adjustment in accordance with the procedures below.
(1) The types or the intervals in image quality controls must be adjusted by setting the most appropriate
value for [08] code in accordance with the status of use or stability level required by a user. See the
table below for an overview of image quality controls.
Overview of image quality controls:
* 1. The correction accuracy is high but it takes approx. 90 seconds (equal to the time taken by
existing models). This control is performed with a simple calibration operated from the control
panel.
* 2. The control with the simple correction takes approx. 15 seconds, but its correction accuracy is
not as high as the one in the Full Mode.
