Calibration

The printer has many advanced features to help you produce the best printed output with the least effort.

◆Micro-QuadTMprintheads — sixteen 600 dpi, 25 picoliter piezoelectric printheads (four per color).

◆AutoCleanTM service station — a motorized service station that wipes the printheads with cleaning solvent automati- cally to keep all jets firing properly.

◆Purge-n-WipeTM— combines an air pressure purge with a cleaning solvent wipe of the printheads to recover clogged jets.

◆AutoRecover — performs a Purge-n-Wipe at the start of a print job (before printing) if a Purge-n-Wipe has not been performed for a specified amount of time.

◆Automated printhead maintenance — to keep individual inkjets from drying out, the printer periodically “spits” a small amount of ink and performs a Purge-n-Wipe cycle.

◆Capping station — manually-operated capping station pre- vents drying out of printheads when idle. The printer senses the position of the capping pad to prevent carriage move- ment while capped, or to prevent the carriage from moving to the capping station if the pad is raised.

◆Off-Head System (OHS) — 3 liter bulk ink boxes with profil- ers supply the printheads. The printer displays an alert when an ink box should be replaced.

◆Onboard vacuum/pressure (VP) system — provides vac- uum to maintain negative printhead pressure, and air pres- sure to purge the printheads or ink tubes without removing them from the printer.

◆AutoSetTM calibration — uses a high-resolution digital imag- ing sensor to automatically align printheads bidirectionally for precise positioning of ink jet pixels, and runs AutoJet.

◆AutoJetTM calibration— compensates for lost or misfiring jets by locating them and using substitute jets without slowing printing speed.

◆AutoTuneTM scheduling — runs Purge-n-Wipe and/or Auto- Jet at user-defined intervals, for highest quality during unat- tended printing. Optionally, if unsubstituted non-working jets are found, printing stops until the problem is corrected.
