Auto Calibrations

4-6
The printer's piezo printheads are aligned at the factory and
should only occasionally require you to run an automatic bidi-
rectional or head-to-head calibration.
1. On the Front Page screen, press the  (Menu) key to enter
the menu system.
2. Press the  (Menu In) key display the Calibrate Printer
menu.
3. Highlight Auto Calibrations and press the  (Menu In) key.
4. 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 per-
formed 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.
