Abstract
A component, such as an ink cartridge, is provided with magnetic members. A corresponding component in the printer system, such as a carriage, is also provided with magnetic members so that magnetic attraction between the two components provides or enhances the connecting force between those components. The magnetic members on one component (such as the ink cartridge) are arranged in a particular pattern that indicates a print characteristic of the cartridge. The print characteristic may relate to the color of the ink in the cartridge that is used. A corresponding pattern is provided in the carriage. The pattern is such that magnetic force will attract the cartridge when positioned in the correct mating location in the carriage. This magnetic attraction is provided as tactile feedback to the user in the course of seating the cartridge in the correct location. The mating locations of the carriage are provided with various patterns of magnetic member arranged to provide a magnetic repulsion when one attempts to place a cartridge into the incorrect location on the carriage.
