and Mains Air
Regulator Setting
1. Set the mains air regulator (black pointer) to 0.3MPa (3 bar) by turning the
regulator control valve, clockwise to increase the pressure and anti-clock-
wise to decrease it.
2. Turn the cover on the pressure sensor and gauge anti-clockwise and
remove.
3. Set the pressure sensor (green pointer) by using a screwdriver to turn the
brass set screw slowly until the tricoloured beacon changes from green to
red, clockwise to decrease the pressure and anti-clockwise to increase it.
When the tricoloured beacon just changes to red, the pressure sensor is
correctly set at 0.3MPa (3 bar).
4. Replace the cover on the pressure sensor and gauge and turn clockwise to
lock.

Chase Clamp
Regulator Setting
The chase clamp regulator is located at the rear of the left hand print head,
overview diagram in the Screen Alignment Module refers.
There are two procedures for setting the chase clamp regulator depending on
whether a digital or spring balance type forcemeter is used. Select the appro-
priate procedure below:
Digital Forcemeter 1. Remove/open the rear printhead cover.
2. Open the front printhead cover.
3. Set the chase clamp regulator to 0.2MPa (2 bar) by turning the regulator
control valve, clockwise to increase the pressure and anti-clockwise to
decrease it.
4. From the rear of the printer, place the forcemeter up against the rear of the
chase.
5. Noting the reading, gradually push the forcemeter until the chase starts to
slip within the chase clamps. The reading should be between 12.2kg and
13.0kg.
6. Adjust the chase clamp regulator to achieve this value.
7. Refit/close the rear printhead cover.
Spring Balance
Forcemeter
1. Select Open Cover Commands.
2. Select Carriage To Rear.
3. Select Unload Screen.
4. Open the front printhead cover.
5. Remove the stencil from the printer.
6. Fit an empty stencil frame into the chase.
7. Attach a cable tie to the front of the empty stencil frame.
8. Close the front printhead cover.
9. Press the System button.
