Auto Calibrations

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.

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 a pixel at precisely the same loca- tion (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 AutoJet and Auto BiDi Calibration in sequence. The minimum media width allowed for AutoSet is 18 inches (46 cm).

When you select a calibration, the control panel prompts whether you want to perform a Purge-n-Wipe before con- tinuing.

◆Press ! to initiate a Purge-n-Wipe. The printheads are purged, then wiped.
