Performing procedure "(e) Adjust maximum image density" increases the consumption of toner, and it tends to decrease the fusing of toner. Perform this procedure as a temporary solution, and restore the original set value after this printing job.
For details about replacing the parts, see Replacement Guide.
After performing the solution, it is recommended to perform the color calibration of the external controller.
