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).
The automatic calibrations apply X offsets (in the direction of carriage motion) to individual jets. The
manual calibrations apply X offsets to the entire printhead. Because of this, the automatic calibrations
are much more precise and yield better print quality than the manual calibrations.
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
●
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 (Production and High Quality) use jet replacement, so
they can print successfully with a greater number of jets out than can 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.
