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.

Board Clamp
Regulator Setting
The board clamp regulator is located under the front cover, secured to the front
of the right hand printhead, as shown in the graphic below.
Setting the board clamps regulator is detailed in the following procedure:
1. Select Open Cover Commands.
2. Open the front printhead cover.
3. Select Toggle Board Clamps.
4. The board clamp regulator should read 0.5MPa (5 bar).
5. If the pressure regulator indicator gauge does not read 0.5MPa (5 bar) it
requires adjustment. To adjust the pressure regulator, loosen the locknut at
the base of the pressure adjustment screw and adjust the pressure to
0.5MPa (5 bar) by turning the adjustment screw clockwise to increase the
pressure or anti-clockwise to decrease it.
6. Select Toggle Board Clamps repeatedly and check for smooth operation
of the board clamps.
7. Ensure that the regulator maintains a reading of 0.5MPa (5 bar).
8. Lock the regulator adjustment screw in position by tightening the locknut.
9. Close the front printhead cover.
10. Press the System button.
