Abstract:

For applications using multiple print heads, print head alignment is often achieved through a laborious iterative process of print testing and adjustment.

In order to streamline this process, we have enabled an off-line pre-print alignment method. Relying on quantitative analysis rather than educated guesswork, this procedure enables quick and reliable alignment of the print head in the assembly.

This method uses a precision fixture to hold the print head, while a semi-automated image capture and analysis package provides immediate feedback to the alignment technician as to the direction and magnitude of the necessary alignment changes.

The technique described in this paper has benefits both in the manufacturing environment and in field support.

This paper will discuss the details comprising this novel alignment process including the interaction between the user and the system.
