Positioning system

Abstract

A positioning system includes adjustment means for accurately positioning a positioning device relative to a frame. The adjustment means makes a sliding contact with a dedicated lever which makes contact with the frame. The contact surfaces of the dedicated lever are specially shaped in order to obtain a linear behavior of the positioning system. Within a working distance D an equal movement of the adjustment means over a distance Δx is converted into a corresponding movement of the positioning device relative to the frame over a distance Δy. The ratio Δx/Δy is substantially constant for movements within the working distance D. When using the positioning system in a printing system, it is possible to measure the position error of printheads having arrays of printing elements only once and adjust the positioning devices carrying the printheads only once to align the printing elements to each other and to the printing direction of the printer.
