The invention disclosure presented here describes a method for measuring the mass of two
different Ink/Agent Supplies, or any other supply depending the application, using the displacement of
their combined center of masses. This is done using only two separated force sensors, such as load
cells, allocated at the sides of the two supplies.
With this invention the number of force sensors is reduced from typically four per Supply to just
one, which simplifies design, reduces cost and improves reliability.
