CARRIAGE UNIT CONFIGURATION
In this printer, a carriage holding and drive mechanism construction which
differs from previous models is used. The carriage configuration consists of the
following major parts.
o
Base Carriage
:1unit
o
Sub-carriage
:1unit
o
Print Heads
:2 units (Dark system, Light system heads)
o
Slide Eccentric Cam, Slide Gear
The mounting position of the base carriage is maintained at a constant
distance with respect to the paper surface at all times. Consequently, in order
to enable changes in the gap between the paper printing surface (platen
surface) and the head nozzle surface, a sub-carriage is mounted on the base
carriage to which the print heads are fastened.
The sub-carriage is mounted on the base carriage in a state where is can move
in the vertical direction with respect to the paper surface by means of the SLID
eccentric cam, which is driven via the SLID gear. Through this mechanism, the
construction is such that the print heads can move to the set gap position.
Vertical movement of the sub-carriage with respect to the paper surface is
possible only in the case that the carriage is in the home position (HP). At that
time, the SLID motor pinion gear (PG moving motor) and the SLID gear
mounted on the SLID eccentric cam shaft engage, and the SLID cam is driven
by the SLID motor’s rotation, causing the sub-carriage (including the print
heads) to be raised or lowered to the proper gap position.
The print heads used in this printer are the same as those used in the Stylus
Pro 5500 and Stylus Pro 9000, and the head mounting method on the sub-
carriage also has the same construction. Therefore, if the print heads are
removed or installed, or replaced, it is necessary that the respective
inclinations and of the dark system head/light system head in the horizontal
direction (carriage scanning direction) and the light system head nozzle height
with the dark system head nozzle position as the reference in the vertical
direction (paper transport direction) be set with the adjustment lever. For
details, see Chapter 5, “Adjustments.”
