Visual Correction
Visually measure a test page you have output to perform correction using the density adjustment values you determine. Use this procedure when you do not have a densitometer or when correction is not effective.
Use the control panel to perform Visual correction. You cannot perform Visual correction using Remote UI from a computer.

Scanner Correction
You can perform density correction by scanning a test page that you have output. This saves the labor of performing density measurements and entering density values.
Use the control panel to perform Scanner correction. You cannot perform Scanner correction using Remote UI from a computer.

On the control panel, press [Menu] in the [Home] screen. [Home] Screen
Check that the size and type of paper displayed on the screen is loaded in the machine, and press [Start].

Place the test page on the platen glass.
Place the test page sheet in the machine in a manner that its side on which the four color stripes are printed faces down and the cyan stripe faces toward the back side of the machine.
7
Close the feeder or the platen cover and press [Start Scanning].
The test page is scanned and density correction is performed.
If the [Could not perform correction.] message is displayed
Did you load the paper displayed in step 5 into the paper source?
Did you place the adjustment image with the print side face down, with the black stripe toward the back side of the machine?
Is the amount remaining in toner cartridge required for correction sufficient? If the amount remaining in a toner cartridge is low, it is recommended that you replace toner cartridges. Checking the Remaining Amount of Consumables
