The printer system is made up of several sub-systems (see Figures 3-1 and 3-2):
•
Universal Power Supply
- The universal power supply has auto sensing/
switching for input voltage and intelligent shutdown capability. It ensures
proper parking of the cartridges in the maintenance station and proper
shutdown of the software. (It is the same supply used in the midrange
DM series mailing machines.)
•
System Controller
- The system controller is comprised of the overall op-
erating system in the firmware that controls the behavior of the system
and coordinates activities between the other sections.
•
User Interface
- The user interface is the LCD display, the buttons, and
the software to drive it within the firmware.
•
Feeder and Transport Motion Control
- The feeder and transport motion
control is responsible for feeding and positioning the envelope beneath
the printer for printing. All material motion is controlled by the transport
motor and firmware.
•
Head Motion Control (Head Management)
- The head motion is a combi-
nation of shuttle motion control and head management result in printing
1/2” swaths across the envelope as required. These work in conjunction
with the transport motion control for proper positioning of the printed mate-
rial on the envelope.
•
Communications
- The communications hardware and firmware are re-
sponsible for the interface to the host PC through which print streams are
received and passed to the system controller for parsing and rendering.
