This article will run you through the process of aligning your printer.
Due to manufacturing tolerances each Argentum will have a slightly different alignment value. The alignment consists of a Vertical offset and Horizontal components. The Vertical offset is the distance between the two ink cartridges in the printers y axis. The Vertical offset is the distance between the two ink cartridges in the printers x axis.
The alignment menu can be found in the ARC software under Utilities > Processing Options. This is what it looks like:
Misalignment can be seen
The fastest way we've found to determine the optimal values for Horizontal_offset and Vertical_offset is to print an image, look at the alignment, change the offset in the appropriate direction and print the image again. When you're happy with the alignment you can stop.
