Procedures
* The procedure to use varies, depending on whether to adjust the copy image quality in the Black mode or the
Full color mode. Refer to the procedure corresponding to the user’s particular request.
* Refer to the procedure to adjust the copy image quality in the Full color mode with the Printed image mode selected,
in order to adjust the copy image quality in the Black mode with the Photo mode selected. The value adjusted is
shared in the Black mode with the Photo mode selected and in the Full color mode with the Printed image mode
selected. Therefore, adjusting the copy image quality in either of the modes affects that in the other mode.
