3. Attach a dial indicator to the head bracket.
4. Attached the head to the toggle head assembly.
5. Move the dial indicator to the back left (BL) corner over the marked loca-
tion.
6. Raise the Z Stage until it contacts the dial indicator. Continue to raise the
Z stage approximately two additional revolutions of the dial indicator.
Wedge a screw driver or similar object between the underside of the
table and the bottom of the chamber to prevent the Z stage from moving
downward.
7. Zero the dial indicator (this is the reference position and will always be
zero).
8. Next move the XY table until the dial indicator is over the front left (FL)
corner mark Figure 401 Measure and record the difference (e.g. the dial
indicator reads 0.004 in.)
9. Move the XY table until the dial indicator is over the front right (FR) cor-
ner mark Figure 401 Measure and record the difference (e.g. the dial
indicator reads +0.010 in.).
10. Move XY table until the dial indicator is over the back right (BR) corner
mark Figure 401 Measure and record the difference (e.g. the dial indi-
cator reads +0.008 in).
11. Enter the values that are written down into the XY level worksheet. Use
the 8x6 worksheet for HP Designjet 3D, see Figure 402. Use the 8x8
worksheet for HP Designjet Color 3D, see Figure 403.
