Clear All Bad Jets
When you select Clear All Bad Jets, the control panel displays the following prompt:
Are you sure you want to clear ALL reported bad jets?
● Press Cancel to cancel this function, or
● Press Proceed. The control panel displays this message:
Do you want to clear the hard bad jets?
● Press No to clear the soft bad jets only, or
● Press Yes to clear both the hard and soft jets.
The control panel displays this message:
All reported bad jets have been cleared.
▲ Press Proceed (►).
When you have finished mapping jets, the following summary appears on the control panel:
x soft jets currently reported bad. x hard jets currently reported bad. x new soft bad jets reported.
x new hard bad jets reported. x previous soft bad jets cleared. x previous hard bad jets cleared.
where x is the number of jets.
Default Registration Data
This option enables you to reset bidi registration, head-to-head registration, or jet mapping data, or
any combination of them. After running this option, the deleted calibration values must be
reestablished by running the calibrations.
Unfixed Jets Report
The Unfixed Jets Report displays a table showing, for each print mode, which colors are printing with
non-working inkjets that are not being automatically replaced with working jets by AutoJet mapping
(“unfixed” inkjets). For each combination of ink color and print mode, “No” means there are no unfixed
jets, “Yes” means there are unfixed jets.
Linearization
As the density of an image varies from highlights to shadows, or from lighter tints to darker tints, the
printer should accurately reproduce these areas in a predictable, or linear, fashion. The process of
linearization (or color calibration) involves printing and reading color test patches, and calibrating the
printer to ensure that the expected and printed densities will match. This in turn will ensure optimal
color matching.
Color calibration is a feature of the RIP connected to the printer. Refer to the documentation that
accompanies the RIP for further information.
