Color Adjustments The following color settings can be configured. SYSTEM SETTINGS OPERATION PANEL (ADMINISTRATOR) Initial Color Balance Setting Color balance values obtained using "Color Balance" in the special modes can be stored in a job program (1 to 48), and those values can be retrieved and stored as the initial color balance setting*. Use this feature when you want to repeatedly use a color balance setting for a favorite color or for correction when a change occurs in the color balance. * Preset values displayed when you select "Color Balance" in the special modes. Return to the Factory Default Setting This returns the stored color balance values to the factory default values (all color balance values are "0" for the 8 levels of each color). Auto Color Calibration This is used to perform automatic color correction when the color copy output appears to contain the incorrect colors throughout the document. The machine prints a test patch, the test patch is scanned, and the color is automatically corrected. Make sure to load 8-1/2" x 11" or A4 white plain paper in the machine. After the [Execute] key is selected and a test patch is printed, a message appears prompting you to begin automatic calibration. Place the test patch on the document glass as shown below (so that the thin line at the edge of the page is to the left). Thin line mark Align the middle of the test patch with the tip of the mark. Lay copy paper (about five sheets) that is the same size as the test patch on top of the placed test patch, gently close the automatic document feeder, and select the [Execute] key. • Before executing Auto Color Calibration, check to see if the registration adjustment is correct. If the registration adjustment is not correct, perform "Registration Adjustment" (page 6-27). • If the color is still off after performing Auto Color Calibration, repeating Auto Color Calibration once again may improve the color. 6-31 Contents
