Component
Switches the machine on/off.
Mounted at the left rear corner of the printer, the horizontal
motor alternately runs forward and reverse to drive the timing
belt that moves the carriage to the left and right during
printing. The operation of the motor is controlled by the
horizontal encoder strip stretched across the width of the
printer and threaded through the horizontal encoder sensor
on the right rear corner of the carriage unit. The sensor reads
this strip as the carriage moves from side to side and uses
these readings to control the operation of the motor.
A push switch mounted on the left post of the main machine
that detects when the pin on the left end of the front cover is
mounted correctly in its track.
The intuitive 10.1 inch operation panel eliminate all hardware
key from the panel.
