Perform calibration if colors change or color mismatch occurs and you cannot print the correct colors (the colors you specified)

When all the printout results appear reddish or bluish, or the color balance is not appropriate, you can correct the colors by adjusting each toner density of C (Cyan), M (Magenta), Y (Yellow), and K (Black).

If the printed paper has smudge marks, clean the inside of the printer.

Print quality deterioration can be prevented by cleaning the inside of the printer.

Periodically clean the outer surfaces and ventilation slots of the printer to maintain the optimal printing quality.
