Electrical System |
| |
|
| The electrical system of the Printer
consists of six major blocks and their associated cabling:
|
| |
|
-Power Supply Unit:
Connected to the mains supply of whichever country this block provides
24V, 5V, 3.3V and -15V to the rest of the electrical system. It has
a soft power switching feature allowing the firmware to control when
power is removed from the system, and eliminates the need for high
tension cables to the front panel.
-Main Electronics: This block contains the I/O, central
processing units and controls most of the motors and sensors in the
printer. The motors and sensors themselves are located throughout
the printer and are connected to the main electronics via cables.
-Carriage: Connected to the Printheads, this block
supplies power to them, as well as monitoring and protecting them
from damage. It also has the ability to control warming and to perform
continuity checking, as well as controlling the Line Sensor. The Carriage
Encoder is also located in this block.
-Ink Supply Station: The Ink Supply Station is connected
to the Ink Cartridge supplies, and controls air pressure (pump, sensor
and valve), as well as monitoring ink levels and the supply latch
sensor.
-Service Station: Contains the electronics needed
to perform drop detection, a DC motor/encoder for capping, wiping
and spitting and a stepper motor for priming.
-Front Panel: is the user interface. It consists
of an LCD display, a key panel and four LEDs. |
