HP (Hewlett-Packard) 98SI Printer User Manual


 
Special Features 1-15
Special Features The printer has many advanced features to help you produce the
best printed output with the least effort.
Printheads Micro-Quad
TM
printheads — sixteen 600 dpi, 25 picoliter
piezoelectric printheads (four per color).
AutoClean
TM
service station — a motorized service station
that wipes the printheads with cleaning solvent automati-
cally to keep all jets firing properly.
Purge-n-Wipe
TM
— 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.
Ink System 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.
Calibration AutoSet
TM
calibration — uses a high-resolution digital imag-
ing sensor to automatically align printheads bidirectionally
for precise positioning of ink jet pixels, and runs AutoJet.
AutoJet
TM
calibration— compensates for lost or misfiring jets
by locating them and using substitute jets without slowing
printing speed.
AutoTune
TM
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.
