# Cleaning and Maintaining the Printer

#### Adjusting the Color or Color Mismatch (Calibration)
| Perform calibration if colors change or color mismatch occurs and you cannot print the correct colors (the colors you specified)
#### If You Want to Adjust Color Balance
| 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).
#### Cleaning the Inside of the Printer
| 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.
#### Cleaning the Outside of the Printer
| Periodically clean the outer surfaces and ventilation slots of the printer to maintain the optimal printing quality.
