A user discovers that color laser prints are printing slightly off-color. Which of the following should help restore the appropriate colors?

While paper type and finish can influence how toner adheres and reflects light, switching paper does not address the underlying toner density imbalance or color profile drift that causes off-color output.

The fuser applies heat and pressure to bond toner to the paper - replacing it corrects issues like smearing or poor adhesion, not color accuracy or tonal imbalance.

The duplexer is the mechanism for printing on both sides of a page - it has no role in color mixing, toner density, or color profile management.

Color laser printers use four toner cartridges (CMYK) whose relative densities and alignment must be precisely balanced to produce accurate colors. Calibration runs an internal diagnostic that measures toner output and adjusts density curves and color registration, restoring accurate color reproduction without replacing any hardware components.
