  • Patent number: 9333753
    Abstract: A cap 13, 15, for the print face 9 of a drop-on-demand ink jet printer moves between a closed position, in which it covers the print nozzles on the print face 9, and an open position in which the print nozzles are uncovered, without requiring movement of the print face 9. In the open position, the cap is recessed relative to the front surface 21 of the printhead. For at least part of the movement of the cap, it is further forward than the print face 9, so that it does not slide across and damage the print nozzles. The drop-on-demand ink jet printer may be used to print onto objects 3 conveyed past it, for example on a packing line. The cap 13, 15, does not obstruct the path of the objects 3 even if they pass very close (e.g. 0.5 mm) to the print face 9 because its uncapped position is further back than the front surface 21 of the printhead.

  • Patent number: 9327514
    Abstract: A common air chamber is connected to an air layer of a pressurizing tank and to an air layer of a negative-pressure tank. A pressurizing-side communication valve opens/closes an air channel in an air conduit between the pressurizing tank and the common air chamber. A negative-pressure side communication valve opens/closes an air channel in an air conduit between the negative-pressure tank and the common air chamber. A negative-pressure tank atmospheric air opening valve switches the negative-pressure tank between a state shut off from the atmospheric air and a state open thereto. The pressurizing-side communication valve and the negative-pressure tank atmospheric air opening valve are of a normally-open type closed when electrified and open when not. The negative-pressure side communication valve is of a normally-closed type open when electrified and closed when not. While not electrified, a nozzle pressure of an inkjet head becomes a meniscus breakage pressure or less.
