Index Description
1Encoder strip — allows precise positioning of the print-
head carriage across the length of the platen.
2 Main carriage drive belt — moves the carriage across
the length of the platen.
Transport chain (not shown) — supports the ink sup-
ply tubes that carry ink from the ink supplies to the
printheads, power, and electrical signal cables.
3Platen — supports the media under the printheads
during printing, warms the media in the print zone,
includes vacuum to hold the media against the platen.
4 Printhead carriage — carries the printheads, digital
imaging sensor, and photodiode across the length of
the platen.
Digital image sensor (on carriage, not shown) —
detects the location of printed pixels for precise align-
ment of the printheads, enables the automatic replace-
ment of poorly-printing ink jets with substitute jets.
Photodiode (on carriage, not shown) — enables the
creation of color transforms without an external spec-
trophotometer (requires print server support), and the
linearization of existing transforms.
5 Spittoons — located at both ends of the platen,
receives ink “spits” that keep the printheads at their
optimal performance.
6AutoClean
TM
Service station — catches purged ink
from the printheads, wipes the printheads with clean-
ing solvent. Wipers are automatically cleaned and
cleaning solvent applied before wiping. Ink is periodi-
cally spit when idle to keep the inkjets working.
7 Ready-for-Refill LEDs — an LED illuminates when its
corresponding profiler indicates that the ink box
should be replaced with a full one.
8 Control panel — displays messages and allows control
of certain printer operations. Includes a contrast adjust-
ment lever and audio feedback.
9Electronics module — contains the printer’s power
supply and control electronics.
10 Postheater — helps to dry the output prior to the
takeup. Incorporates turnbuckles that can be adjusted
to straighten the media path.
