When to calibrate
When to run Calibration Function
When loading a new media (but not
when loading a new roll or sheet of the
same media) Linearization (see RIP documentation
for instructions). Linearization of colors for accurate color
matching.
Horizontal Banding Media Feed Calibrates the media advance.
Poor output quality (apparent
misregistration of colors, banding) Auto Calibrations Calibrates the position of ink droplets in
relationship to each other and corrects
for individual jets not operating properly.
You can also run the Manual
Calibrations if necessary.
When printheads have been moved or
replaced (by an authorized service
provider) Auto Bidirectional or Manual
Bidirectional, and Head-to-Head Head calibrations. Run Manual when
calibrating transparent or other media
that the onboard digital image sensor
cannot calibrate.
If Auto Calibrations do not improve print
quality, or if printing on transparent or
other media that cannot be detected by
the printer Manual Calibrations Aligns printheads, allows you to map
out specific inkjets. Not normally
needed except when printing on
“invisible” media.
AutoJet
AutoJet detects individual inkjets that are misfiring or not firing at all. During subsequent printing, the
printer compensates for these jets by using other jets in their place, ensuring maximum print quality
without reducing print speed.
You can also identify and map missing jets manually from the Manual Calibrations menu (see Manual
Jet Mapping on page 50 ). You may want to manually map weak or misdirected jets that AutoJet
does not detect and substitute.
Jet replacement is not available in Express mode.
To run AutoJet:
● Select AutoJet Calibration from the Auto Calibrations menu (see Auto calibrations on page 46 ),
or
TIP: AutoJet does not work with transparent media, nor with many translucent media. In this case,
run Manual Jet Mapping, or map jets on opaque media before loading transparent/translucent media
for printing.
1. Press Calibrate from the Printing page, then press Auto Calibrations > AutoJet Calibration in
the menu.
2. The printer prints the AutoJet test pattern.
3. The printer reads the AutoJet test pattern and maps any missing jets to available working jets.
