2.1.1.3 Cleaning Mechanism
This printer's cleaning mechanism has the same mechanical configuration as
that in the Stylus Pro 5500 and Stylus Pro 9000. (However, it differs in its
component parts. See below for details.) The major component parts are
described below.
o
Pump Assembly (Cleaner, head installation)
Suction of ink from the head nozzle through the cap is used to accomplish
cleaning. Through rotation of the pump wheel, and by pressing the ink
tubes connected to the cap, the internal pressure change accompanying
the change in the tubes' internal volume causes the ink to be sucked up.
o
Pump Drive Motor (Stepping Motor)
This is an exclusive motor that drives the pump assembly.
o
Cap Assembly (Independent type for the dark system head and the light
system head)
This protects the print head nozzles when they are not operating and seal
off the head nozzle surfaces during the cleaning operation. The cap
assembly in the Stylus Pro 9500 uses new tubes to reduce evaporation of
the moisture in the ink.
o
F Box R
This is a receptacle for the ink that is discharged during flushing, with the
ink being discharged to the waste ink tank. In order to carry out flushing on
the side opposite the HP side, the F box L and waste ink tank (L) are also
provided separately. As for flushing in the Stylus Pro 9500, in order to
prevent mist from forming on the head nozzle surface during flushing and
in order to prevent the mist from condensing on the flushing box discharge
outlet, a construction with a new part (bell eater) added has been adopted.
Each of the above units is mounted on the sub-frame and fastened to the main
frame. (However, the F box L is a separate unit.) The CR lock mechanism is
also mounted on this sub-frame.
