About the Auto Color Diagnosis Function

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.

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.
