Adjusting Gradation

Gradation Adjustment
When the color gradation of the printed image is incorrect, you can easily adjust it.
Through this gradation adjustment, the image quality of this machine can be
consistently maintained.
Gradation adjustment is divided into two types, resolution preferred and gradation
preferred.
To adjust the gradation of the High Resolution-conscious part like text, select
resolution preferred . To adjust the smoothness of gradation for graphics and photo
images, select gradation preferred.
When adjusting gradation, print the gradation adjustment chart and compare it with
“Color sample for halftone reproduction tuning” included with the printer to get the
value for [Lighter/Darker] settings, and set this value for the printer.
You can specify low density (Low)/middle density
(Mid)/high density (High) for C (cyan), M (magenta), Y (yellow), K (black).
To reset the value in [Lighter/Darker] to the default value after gradation adjustment,
set all values to [0]. If all values are set to [0], gradation adjustment is disabled.
●
If color gradation is often out even after gradation adjustment, contact our Customer Support
Center or your dealers.
●
Resetting values in [Lighter/Darker] to the default value (all [0]) does not mean that the image
quality returns to the quality that you could get first at installation time. Using the printer for a long
period, the image quality has differed from that at installation time under influence of aging,
change in the environment, and amount printed.
