10.1.4 Screen Alignment

The screen alignment consists of the following sub-assemblies:

●

3x screen actuators (Xf, Xr, Y)

●

2x chase clamps

●

4x chase roller counter plates

●

Chase clamp air regulator

●

Dual stepper drive cards (X1 & X3)

Screen actuator

Replaced as complete assembly.

Chase Clamps

1. View on front Left or rear right printhead

2. Roller counter plate

3. View on roller bearing assembly

4. Roller bearing assembly

5. Locking nut

6. Chase clamp

The chase clamps consist of a pneumatic cylinder sitting on a plate with a rubber seal underneath.

●

Once the frame has been fixed in position the chase will clamp the screen in place.

●

There should be a force of 12kg.

●

There is a pneumatic regulator on the rear of the machine to adjust the force.
