Abstract
The invention describes a facility to provide an indication of level in a container of conductive liquid used in an inkjet printer. The facility comprises an array of nested capacitive sensor pads, the outputs of which can be processed to provide a continuous indication of level. The outputs can also be processed to provide an indication of whether the container is mis-aligned on the printer.
