Important • Because the Tray 5 (Bypass) is used for calibration, load plain paper in the Tray 5 (Bypass).
Any other types of paper are not available. For more information, refer to "Paper Size/Type"
(P.277).
Note • It is recommended that you perform adjustments for all the screen types. After one screen
type is adjusted, specify another screen type and repeat the adjustment procedure.
• If color gradation is not compensated despite the periodic calibration, contact our Customer
Support Center.
• Calibration does not execute when [Text] or [Map] is selected for [Original Type] in the
[Image Quality] tab for copying. Before calibration, make sure that [Copy Defaults] in the
System Administration mode is set as follows: Lighten/Darken: Normal, Color Shift: Normal,
Saturation: Normal, Color Balance: 0. After finishing the calibration, change the settings of
[Copy Defaults] if necessary. For information about the [Copy Defaults], refer to "Copy
Defaults" (P.293).
