主权项

1. A cleaning-in-place system for inkjet printing heads comprising:
a. a mask having an upper surface and a lower surface, the mask defining:
i. a cleaning window;ii. a printing slit; andiii. a purge well recessed into the upper surface of the mask; b. a print head having a distal end, a proximal end, a longitudinal axis, and a transverse axis, the distal end having lower surface defining at least one orifice; c. a three (3) dimension alignment assembly, operably coupled to the print head and the mask; and d. a bracket, operably coupled to the alignment assembly, wherein the mask is configured to selectably align the cleaning window, the printing slit, or the purge well with the printing head's at least one orifice.
