Figure 3-2. The Control Unit
The control unit consists of the hydraulic and electronic
compartments of the printer, as well as the keyboard
(Refer to Figure 3-2).
The hydraulics compartment is located behind the front
door of the control unit (refer to Figure 3-2). This is where
ink and makeup fluid are stored, monitored, and
maintained to ensure proper fluid viscosity. This is also
where pressure is applied to the ink to ensure proper
velocity of the ink drops at the printhead.
Caution: The hydraulics compartment is also
commonly referred to as the "fluid pan".
Refer to Hydraulic Components on page 3-7 for
information on the main components found in the
hydraulics compartment.
