The printhead pressure system is the mechanism which drives the two squeegees independently down onto the screen and applies the pressure necessary to print.
- m6 ?$ S7 N JThe pressure being applied during print is monitored by the pressure amplifier,and if necessary, corrections to pressure is made as part of a closed loop process. The load cell and pressure amplifier give a change in output voltage proportional to the pressure applied by the squeegees.
* f" R/ l: J7 a9 e/ i+ eThe pre-load set screw and main compression spring are used to calibrate the load cell/squeegee pressure.
