About the Auto Color Diagnosis Function
This section explains the Auto Color Diagnosis function, which is one of the functions of the Auto Color
Diagnosis Unit.
This function uses the in-line sensor to scan the printed colors while a continuous print run is in progress,
and suppresses color deviation without stopping the machine.

Tone Correction
Monitoring and Adjusting Colors Automatically
To suppress color deviation during a continuous print run, the machine compares the recently
printed colors to the colors initially printed at the beginning of the print run, and adjusts the colors
automatically.
• You cannot enable or disable the Auto Color Diagnosis function individually for each print
job.
• You need a sufficient number of measurement points in the image to be printed for the function
to be effective.
Generating and Registering Paper Properties
To adjust colors correctly, generate paper properties for each paper type. When generated, this
information is stored in the machine's data storage. The machine reads the properties of the paper
used for printing from the storage and adjusts colors according to the information.
Supported Paper
The paper supported by the Auto Color Diagnosis function is as follows:

Paper attributes Requirements
Paper size 210 mm (8.3inches) or more vertically × 279–700 mm (11–27.6inches)
horizontally; or 279 mm (11inches) or more vertically × 210–700 mm (8.3–
27.6inches) horizontally (including custom and banner paper)
Paper weight Paper weight "1" or greater
Paper type Plain paper, recycled paper, high gloss paper, gloss paper, matte paper, or
synthetic paper
Paper color White
• You cannot use the Auto Color Diagnosis function when printing on a sheet of paper that has been
manually selected instead of selected from the media catalog.

Generating Paper Properties (When Using
Fiery)
To use the Auto Color Diagnosis function, print the color chart and generate paper properties for each
paper type. When generated, this information is stored in the machine's data storage and used for
adjusting colors when printing is performed.
To adjust colors properly, perform calibration before generating paper properties.
• Colors are adjusted using the Auto Color Diagnosis function when printing is performed on the
paper for which paper properties are generated.
• Up to 9 sheets of paper are required to generate paper properties.
• Generate this information again after:
• Changing the data registered in the master library (custom paper) via the machine's control
panel
• Changing the printing speed in the paper settings
• Replacing the Line Sensor
• Changing the maximum density (D-MAX) while performing calibration
• Changing the color profile registered in the paper catalog
• For details about the paper catalog, see the "Utilities" manual for the Fiery controller in use.
Using the "ACD Property" Screen
The "ACD Property" screen displays a list of paper types that can be used on the machine. In the screen,
you can generate paper properties, check the generation status, and specify the accuracy setting of the
information.
Viewing the generation status of paper properties
1. Click [Launch ACD] in the "WebTools" screen.
2. Log in with a user name and password.
When a large number of items is registered in the paper catalog, it may take a few minutes to
display the "ACD Property" screen.
The security warning screen may be displayed in your web browser when you access the
"WebTools" or [Launch ACD] screen.

When the warning screen is displayed, ignore it and continue browsing the web page.
3. Check the generation status of paper properties in the "ACD Property" screen.
In the screen, you can view the information below. To check whether the Auto Color Diagnosis
function is enabled, check the [ACD status] field.
Display item Description
Name Registered paper name
Weight (gsm) Paper weight
Paper size Paper size (standard/inch/mm)
Tray Number of the tray where the paper is currently loaded
ACD status Disabled Paper properties are not generated.
Enabled Paper properties are generated.
Not Applicable Because the Auto Color Diagnosis
function does not support paper types,
paper properties cannot be generated.
ACD last updated The last registration time of paper properties
Specifying generation accuracies for paper properties
You can specify generation accuracies for paper properties from High Accuracy or Standard. You
cannot modify this information after it is generated. Specify settings before generating the information.

1. Click [Settings] in the top right corner of the "ACD Property" screen.
EDD651
2. Select the accuracy (High accuracy/Standard) of paper properties, and then click [OK].
The number of color charts to be printed is 5 for "Standard" and 9 for "High accuracy".
Generating Paper Properties
To generate paper properties, select the paper in the "ACD Property" screen.
• Specify the generation accuracy by following the procedure described in page 7 "Specifying
generation accuracies for paper properties" before generating paper properties.
• After changing the color profile registered in the paper catalog, generate the color properties
again. If you use the machine without generating the color properties, Auto Color Diagnosis may
fail or the hue of the printed image may vary excessively.
1. Load sheets of paper in the tray, and select the tray from the media catalog using the
machine's control panel.
When generating paper properties, depending on the precision of the selected paper properties,
the machine prints color charts on 5 sheets of paper (for "Standard") or on 9 sheets (for "High
accuracy"). Load paper for printing charts in the paper tray.
For details about how to select the tray from the media catalog, see "Specifying a Custom Paper"
Preparation.
2. Perform calibration.
