Both the Carriage and Feeding assembly are driven by servomotors, which are controlled by their
respective Servo Driver can prove high precision motion as to enhance the printing quality.
4.4.1 X-axis Movement (Carriage Motion System)
X-axis movement System serves for carriage which will drive the print head moving. The Servo
Motor is responsible for the carriage movement from left and
right. The print head carriage is driven by the Servo Motor
through the timing belt attached to its gear pulley.
4.4.1.1 Servo Driver & Motor
This machine used ACS806 Servo drive and
motor as powerplant. The servo driver installed at the right
side behind the Beam, while the servo motor installed at
the right side of the beam. Servo driver is a transfer
station, which will get movement signal from USB Board
then control the motor working.
4.4.1.2 Raster Reader (116-0340-020) & Strip (141-0134-004)
Raster reader is a optical reader, raster strip is a rasterized transparent plastic. They
work together generate fire signal that will be send to Printing control Board. The raster reader
is fixed on the right side of the carriage, while the strip is installed along the beam.
Notice: The raster reader set-up must up to standard.
4.4.1.3 Limited Switch & Protection Rubber
There are three limit switches for used as electrical protector on this machine. Two of
which are installed at the left end of the beam at carriage home position. The left most serves as
limit switch for carriage left stroke and the inner side serves as the home position switch. The
third is installed at the right most end of the rail serves as the limit switch for carriage right
