In the [Main Unit: Image Quality] group on the [Adjustment Settings for Operators] menu, select 0212: [Productivity Priority Mode], and then change the setting from [Normal] to [Productivity Priority].
In [Normal] Productivity Priority Mode, fusing may be poor when switching from thinner paper to thicker paper due to the fusing temperature being too low for the thicker paper. Conversely, when switching from thicker paper to thinner paper, glossy streaks or other issues may result due to the fusing temperature being too high for the thinner paper.
If Productivity Priority Mode is set to [Fusing Priority], a longer waiting time will be required because it takes longer to adjust the fusing temperature when switching between different paper brands, thicknesses, sizes, and other properties. This will reduce productivity.
