1. General Adjustments – Copying, Printing and e-Filing (Output from Box)
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 halftones 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.
