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 carriage 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 missing 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 substitutions. After completing the calibration(s), 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 (Production and High Quality) use jet replacement, so they can print successfully with a greater number of jets out than can Billboard mode. 4-6 Auto Calibrations

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.
