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
