Frequent calibration may affect the lifetime of toner cartridges. When the remaining amount of toner in cartridges is low, performing calibration may result in a disruption of color balance. If this occurs after calibration, it is recommended that you replace any toner cartridges that are low. Checking the Amount of Remaining Toner

The machine performs automatic adjustment (automatic calibration) in accordance with changes in the usage condition or environmental conditions. You can make a setting so that calibration is automatically performed immediately after the machine is turned ON or you can set the calibration frequency. First Calibration Calibration Freq.

## Correcting Print Color Mismatch

Print color mismatch refers to a shift in the positions of colors that may occur when printing one image with multiple toner cartridges. Color mismatch can cause printouts to appear blurry. When color mismatch occurs, use the following procedure to perform a calibration to correct the problem.

## Correcting Hues

Hue refers to the density of a color such as red, yellow, green, blue, or purple. When hues in the printed image are different from those in the original, or when some colors are darker or the overall density of the print is thinner than in the original, use the following operation to perform a calibration.
