SELF-CLEANING INK JET PRINTER AND PRINT HEAD WITH CLEANING FLUID FLOW SYSTEM |
摘要 |
According to one embodiment of the present invention, a print head comprises a print head body defining an interior chamber and an orifice plate. The orifice plate has an outer surface and further defines a cleaning fluid orifice through the orifice plate for conducting a flow of a cleaning fluid through the cleaning fluid orifice and onto an outer surface of said orifice plate. The orifice plate also defines a drain orifice for conducting a flow of cleaning fluid from the surface to the interior chamber. A supply of pressurized cleaning fluid is disposed in said cavity and connected to the cleaning fluid passageway. During cleaning operations, the fluid flow system defines a flow of a cleaning fluid from the passageway and onto said outer surface. The drain orifice receives cleaning fluid from the outer surface and channels the cleaning fluid into the fluid return.
