Correcting the Gradation
When printing or making a copy without special settings, you can adjust images properly if the gradation, density, or color of the printed paper is different from that of original documents.
There are the following three types of gradation correction.
Important:
- Load the test chart properly. If the test print is not scanned properly, correction cannot be performed properly.
- Check the temperature of the installation site. If the room temperature is low, correction may not be performed properly.
Note:
Count for the test chart
It is counted as color printing.
