3.2.2 Lift Mechanism Assembly
The lift mechanism assembly raises and lowers the fabric roll and plenum chamber assembly dur-
ing the cleaning sweep. Two pneumatically powered lift actuators (one per end) lift and lower the
lifting plate and the assembly mounted on it.
The lift actuators can be optionally fitted with limit sensors (up and down limit) which can signal to
the printer software when a lift/lower activation fails (ie. the actuator is stuck).
NOTE
The limit sensors are not an option on the Long Board (620mm) USC.
In the event that one of the lift actuators gets stuck (either up or down), the left-hand actuator
bracket can pivot and the right-hand actuator top plate has enlarged screw holes allowing the lifting
plate to be stuck at an angle without causing any damage.
The chamber base is supported above the lifting plate on a pair of linear bearings.
NOTE
The linear bearings are not fitted on the Long Board (620mm) USC.

3.2.3 Fabric Roll Assembly
The fabric roll assembly houses the fabric roll, the used fabric take-up roller, fabric drive motor and
fabric usage sensor.
The fabric roll is loaded onto the assembly, the fabric roll tube is pushed onto the sprung plunger
(left-hand end) then onto the brake actuator (right-hand). The fabric runs over the fabric sensor
spindle, turning the vane wheel through the fork opto sensor allowing the printer software to track
fabric usage, over the top of the plenum chamber and then threaded onto the used fabric take-up
roller.
The brake is pneumatically activated, the brake sections move outwards to grip the inner of the fab-
ric roll tube, preventing fabric slippage during cleaning sweeps.
