Inkjet printer with substrate height position control

A substrate holder assembly, comprising:

• a base plate coupled to a support block;
• a contact member coupled to the base plate, the contact member comprising a manipulator with a vacuum surface, a fulcrum, and a plurality of braces coupling the fulcrum to the manipulator, wherein the manipulator and the fulcrum are substantially parallel members;
• a first linear actuator coupled to the base plate and to the contact member to move the manipulator in a first direction and rotate the contact member about an axis that extends in a second direction perpendicular to the first direction, wherein the manipulator and the fulcrum each extend in the second direction;
• a second linear actuator to move the contact member in a third direction substantially perpendicular to the first and second directions;
• and
• a flex member pair coupled to the support block and the contact member, the flex member pair comprising a first flex member and a second flex member, each of the first and second flex members having a flex direction aligned with the first direction.
