1.2 To Adjust the Density on a Solid Colored Image
If the density is decreased
If the density is increased
The solid colored area becomes lighter.
The solid colored area becomes darker.
Explanation
The density of a certain color can be made darker or lighter in accordance with the type of paper or the content of
an original.
When the toner amount on solid areas must be adjusted as requested by a user, an image quality target value or
developer bias must be adjusted.
The correction amount needed varies depending on the status of use of the consumables such as the developer
material or the drums, or the status of the installation site.
Since a constant value will be applied regardless of the influences of the above status in the developer bias
adjustment, perform image quality adjustment while changing the target value as much as possible.
Procedures
* The service technician must perform the adjustment in accordance with the procedures below.
(1) Select [05 ADJUSTMENT MODE]. Adjust the density of the copied or printed solid image.
• Use steps (a) to (b) to perform the adjustment.
