ABSTRACT:
An ink filter (15) is provided in an ink supply conduit (12). First and second electrodes (21), (22) are disposed in the conduit (12) upstream and downstream of the filter (15) respectively. A sensor means (23), (24), (27), (28), (32) measures an electrical parameter such as the electrical resistance, capacitance or the like between the electrodes (21), (22) which varies as a function of the degree of clogging of the filter (15). An indicator (34) such as a light or lights (36), analog meter (33) or the like indicates the magnitude of the electrical parameter and thereby whether the filter (15) is clogged or unclogged.
