associated with development.

- if the density of all colors is low (too light), suspect a fault in the laser exposure system and the transfer block.
b. While Line
If a white line is found in a specific color, suspect a fault in the development system of that particular color.
c. Uneven Density at the Front/Rear
If uneven density is found in a specific color, suspect a fault in the development system of that particular color. If it
is found in all colors, suspect a fault in the drum unit, ITB unit, and laser exposure system.
