Image Quality Adjustment

Use this function to clean the machine's fusing unit when dots or other dirt appear on the printed side of the paper. When this function is executed, "V" printed paper is output and the fusing unit is cleaned.

Adjust black text and the width of black lines. After using this function to perform adjustment, perform [System Settings] - [Common Functions] - [Auto Gray Calibration (for Copy)], [Auto Gray Calibration (for Print)].

If the dark streak reduction is enabled, select any of the following options.
Treat Thin Dark Streaks: Use this setting to make thin dark streaks less apparent. (Low level)
Normal: Use this setting to make dark streaks less apparent. (Medium level)
Treat Up to Thick Dark Streaks: Use this setting to make thick dark streaks less apparent. (High level)

You can easily perform copy quality adjustment in the default state.
You can change the default setting ([2]) to [1 (Smooth)] or [3 (Sharp)].

Factory default settings:

2

You can adjust the gradation, and density of copies.
The density is divided into 3 ranges and you can adjust the level.

Performs automatic grayscale correction.
For copying, adjust with [Auto Gray Calibration (for Copy)]. For printing, adjust with [Auto Gray Calibration (for Print)]. You can use [Copy Calibration by Screen] and [Printer Calibration by Screen] to perform even higher precision adjustment of each mode.
The machine prints a test patch, the test patch is scanned, and the grayscale is automatically corrected.
After the [Execute] key is tapped and a test patch is printed, a message appears prompting you to begin automatic calibration.
Follow the instructions in the message to perform gray adjustment.

If uneven density occurs in a copy and others, use this function to smooth the density.
The uneven density is automatically corrected by scanning a test patch that you print.
After the [Execute] key is tapped and a test patch is printed, a message appears prompting you to begin automatic calibration. Follow the instructions in the message to perform density smoothing.
If there are no problems after adjustment, perform "Auto Gray Calibration (for Copy)" and "Auto Gray Calibration (for Print)".
To return the adjusted values to their factory default state, tap [Return Density Smoothing Adjustment Value to Defaults]. If you tapped [Return to the Defaults], perform adjustment of the density that you want to readjust (medium density in the default mode).
