Abstract

In this paper, the mechatronic design of an active printhead alignment mechanism for multi-printhead inkjet printers is presented. Theposition of each printhead can be independently controlled for the purpose of printhead alignment, by which print quality is improvedwithout tightening the manufacturing tolerances. The design of a short stroke movable printhead mechanism with an actuator is discussed,aiming at a positioning accuracy within 10 lm. A dynamic finite element model is developed to determine the eigenfrequencies,mode shapes and transfer functions of the printhead guidance mechanism. The principle is validated in closed loop by various tests with arealized prototype. The experimental results show that static as well as dynamic alignment errors are compensated for within the requirementwhereas the manufacturing tolerances can even be lowered.
