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.
●
Patent-pending 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 55 and Order ink supplies
on page 20 for ordering information.
Media handling
●
Automatic head height — printer automatically sets the correct head height above the height of
sheet-fed media.
●
Automatic media width sensing — automatically detects the width and position of sheet-fed
media, for precise image placement (for white or light-colored media that the printer can detect).
●
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.
●
Optional extension tables can be added to the ends of the standard tables to handle longer
sheets of media. See
Order accessories on page 55 for ordering information.
●
Optional roll-fed media supply and takeup system is available to handle roll-fed media. See
Order accessories on page 55 for ordering information.
Calibration
The printer uses a high-resolution digital imaging sensor (camera) and embedded software to align
the printheads, and 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.
