Ink tubes
There are 6 ink tubes that deliver the inks to the printheads in the carriage and two additional tubes which
are used as a support structure. They are bundled together in a carrier and held on a shelf on the inside of the
top cover with clips.
Insulation sleeve
The ink tubes are protected from the high temperatures of the Dryer Assembly by a heat resistant insulation
sleeve, which protects the main body of the tubes that are static.
Upper and lower Ink Supply Station (ISS)
The Ink Supply Station (ISS) is divided into the upper and lower sections. They have six slots for holding the
ink cartridges. Each slot has a unique shape (or lock out) which matches with an equal shape at the end of the
applicable ink cartridge. this arrangement avoids the incorrect insertion of an ink cartridge, which would
cause major damage to the ink system.
There are two places for additional slots but these are covered over.
The upper and lower ISS both contain PCAs, although the top PCA contains more functionality, such as the
pressure sensor, see
Ink Supply Station (ISS) Electronics on page 9.
Non-return valves
The two non-return valves are only for the inks on the lower IDS. This is to ensure that when the pump stops
and the cartridges are nearly empty, that the ink does not flow back to the cartridge.
If a cartridge is nearly empty, with no pressure from the pump, the cartridge bag might increase, and air
might enter the printhead.
With a valve, the ink can go only from the cartridge to the printhead, and not the reverse.
Ink seals
Ink seals interface each ink cartridge with the air and ink tubes. They also contain leakage and end-of-ink
sensors.
