The chart attached “<Chart of Panel & Key Operation    - Visual Calibration - >” illustrates the flow of VisualCal. As

you can see, the operation has some flexibility such as enabling bypassing of Color Test Printing. You can also see,

at the end of the operation, you can make the selections effective or abort all selections or return to the default

settings.

- If you select other languages than English in front panel language menu, the language used in the printouts

change accordingly. For Graybalance selection, Italian and Spanish version of a printout has a translation problem.

In Italian, Yellow and Green is not translated in the front panel and shown as “Y” and “G” whereas shown as “G” and

“V” in the printout.

In Spanish, Blue is shown as “N” in front panel whereas shown as “A” in the printout. Because the order shown in the

front panel and the printout is the same, select the value on the front panel considering the order.

- The color output might become a little darker after calibration.

- Though GrayBalacne page can be skipped in Operation, GrayBalance setting should not be skipped.

- You can check whether visual calibration is performed or not by looking at configuration page.

The printer’s color adjustment feature provides additional creative control over printer’s color production. The color

adjustment screens, accessible via the front panel, allow you to override the printer’s current toner density and

brightness settings. Using the color adjustment controls, you can also increase or decrease the

brightness of an image, or you can increase or decrease the density of each the following colors: red, yellow, green,

cyan, blue or magenta. For example, you may choose to make the blues in an image look surreal

by increasing the density of the blue and the cyan in the image, and increasing the brightness setting.

- You can check how color adjustment is performed or not by looking at configuration page.

- You can adjust only one color at a time.

- If you increase Brightness value, the output become brighter while increasing Brightness value in Printer Driver

makes the output darker.

- Changes made using Color Adjustment are retained until the printer is recalibrated. Or reset the adjusted colors to

the last calibration made using the Reset All to 0 option in the Adjust Color screen; or recalibrate

the printer using VisualCal.
