Special features Printheads ● Printheads - variable drop size, piezoelectric printheads. Ink system ● Off-Head System (OHS) - Bulk ink boxes with integrated filters. No-drip quick connectors simplify ink box replacement. ● Onboard vacuum system - Provides vacuum to maintain negative printhead pressure. ● Patented automated printhead service station - Fully maintains the health of the printheads while idle or in service, without operator intervention. ● HP White Ink Homogenizer - Part of the optional white ink upgrade accessory kit, keeps white pigments dispersed for optimal print quality. The white ink upgrade option and white ink cartridge are required to print with white ink. See Order accessories on page 73 and Order ink supplies on page 24 for ordering information. Media handling ● Automatic head height - Printer automatically sets the correct head height above sheet-fed media. ● Automatic media width sensing - Automatically detects the width and position of sheet-fed media, for precise image placement (for detectable media, otherwise the manual method can be used). ● Built-in static charge abatement - Ionizer bars help dissipate static electric charge from synthetic media. ● Rigid media tables feature a flip-up top for space-saving storage: it flips up for use, and down for storage. ● Optional extension tables can be added to the ends of the standard tables to handle longer sheets of media. See Order accessories on page 73 for ordering information. ● Optional roll-fed media supply and takeup system with table-top roll holder is available for handling roll-fed media. See Order accessories on page 73 for ordering information. Calibration The printer uses a high-resolution digital imaging sensor (camera) and embedded software to align the printheads, and to detect and replace missing jets. Manual and automatic calibrations are available. ● AutoSet calibration - Automatically aligns printheads bidirectionally for precise positioning of inkjet pixels, and runs AutoJet. ● AutoJet calibration- Compensates for most lost or misfiring jets by locating them and using substitute jets without slowing printing speed.
