The control panel shows the progress of this operation as the percentage completed.
4. The printer prints an AutoJet report.
NOTE: The AutoJet calibration requires that the printheads are in correct alignment. If AutoJet
maps out a large number of jets even though there are no obvious jetting problems, the printhead Y
calibration (a factory calibration) may need to be performed again. In this case, contact HP or your
authorized service provider.
Auto calibrations
The printer’s piezo printheads are aligned by the installer. Head and bidirectional calibrations should
be necessary only rarely (for example, when the heads have been moved within the carriage or
replaced).
1. Press Calibrate from the Printing page, then press Auto Calibrations in the menu.
2. Select one of the Auto Calibrations.
● AutoBiDi (bidirectional) Calibration — ensures that every working jet fires at precisely the
same location (regardless of the carriage direction of travel).
● Auto Head X (head-to-head) Calibration — ensures that the printheads are in alignment
relative to each other.
● AutoJet Calibration — locates and substitutes missing jets for working jets (see AutoJet
on page 45 ).
● Full AutoSet — runs all three calibrations in sequence. The printer prints a test pattern then
reads it and makes the necessary adjustments or jet substitutions. After completing the
calibrations, a report is printed that shows:
◦ Calibration results — a summary such as SUCCESSFUL CALIBRATION or an error
message
◦ Header showing the date and time, software version, and printer type
◦ Calibration detail — the calibration data for each head. The AutoJet detail reports how
many jets were mapped out by AutoJet, how many are permanently mapped out by
the operator, and whether the head is usable (from a jetout standpoint) in the various
print modes. The higher quality modes use jet replacement, so they can print
successfully with a greater number of jets out than Billboard mode.
● AutoSet Summary — when enabled, a table of the results of the Full AutoSet calibration is
printed after the AutoSet test patterns. When you enable the AutoSet Summary, you can
show or hide the detailed calibration data.
Manual calibrations
When you run the calibrations from this menu, you evaluate the calibration test patterns visually and
enter the calibration values via the control panel.
▲ Press Calibrate from the Printing page, then press Manual Calibrations in the menu.
The Manual Calibration menu consists of these options:
● Media Feed Calibration — calibrates the media advance accuracy for band-free printing.
Visual and (for rigid media only) camera-assisted calibrations are available.
● Manual BiDi Registration — the manual version of AutoBiDi Calibration.
