4-6 Auto Calibrations
Auto Calibrations The printer’s piezo printheads are aligned at the factory. Head
and bidirectional calibrations should be necessary only rarely
(for example, when the heads have been moved within the car-
riage or replaced).
1. Press the Calibrate key from the Front Page screen, 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).
AutoH2H (head-to-head) Calibration ensures
that the printheads are in alignment relative to each
other.
AutoJet Calibration — locates and substitutes miss-
ing jets for working jets. This is the same calibration
performed as when you press the AutoJet button on
the Front Page screen (see “AutoJet” on page 4-3).
Full AutoSet — runs all three calibrations in
sequence. The printer prints a test pattern then reads
it and makes The necessary adjustments or jet substi-
tutions. After completing the calibration(s), a report is
printed that shows:
Calibration results — a summary such as SUC-
CESSFUL CALIBRATION or an error message
Header showing the date and time, software ver-
sion, 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 per-
manently mapped out by the operator, and whether
the head is usable (from a jetout standpoint) in the
various print modes. The higher quality modes
(Production and High Quality) use jet replace-
ment, so they can print successfully with a greater
number of jets out than can Billboard mode.
