Use the Optimize print quality wizard
Introduction
The off-line screen of the printer operator panel contains the Optimize print 
quality wizard that helps you to correct the problems with the output quality. 
The wizard performs the following actions:
■Calibration
■Recover a nozzle failure
■Align the printheads for the selected media type.
Define the settings for automatic calibration, nozzle failure detection, and 
printhead alignment in the Océ Settings Editor. See the on-line help within the 
Océ Settings Editor application. You can start the calibration, nozzle failure 
detection and printhead alignment from the printer operator panel.
During the Optimize print quality wizard, the system performs an alignment. 
The alignment requires the use of media. Make sure at least one roll of media 
is loaded before you enter the Optimize print quality wizard.
When to do
Before you start the Optimize print quality wizard, first check the following:
■Did you use the correct media type?
■Did you use the correct print mode?
Only start the wizard when you are sure that you used the correct media type 
and the correct print mode and if the output quality is still not satisfactory.

Calibrate the scanner
Introduction
To maintain a consistent quality of the output, the Océ TCS400 scanner 
operator panel has a calibration wizard. 
When to do
Use the scanner calibration wizard to get consistent output of high quality.
Between 2 scanner calibrations, the automatic scanner adjustment stabilizes 
the output quality. The automatic scanner adjustment keeps the scanner 
independent of changes in the environment.
Use the scanner calibration wizard to start a scanner calibration when the scan 
quality decreases.
Use the scanner calibration wizard when the following error message appears 
on the screen.
■Unable to align the cameras. Please calibrate the scanner.
Before you begin
■Turn on the scanner at least one hour before you do the scanner calibration
The scanner needs one hour to warm-up for optimal calibration.
■Clean the glass plate of the scanner
(see ‘Clean the scan area’ on page197)
■Clean the white platen of the scanner
(see ‘Clean the scan area’ on page197)
■Clean the calibration sheet
■The scanner operator panel must display Ready.
■Make sure the IT8 file matches the scanner calibration sheet.
(see ‘Update the IT8 file for scanner calibration’ on page149)
Required tool
The scanner calibration sheet inside the front compartment.
