Embodiment Construction

[0030] The invention has been described with reference to the drawings, in which like elements are designated by like reference numerals. The relationship and function of the various elements of the invention will be better understood from the following detailed description. However, the embodiments of the present invention as described below are just examples, and the present invention is not limited to the embodiments shown in the drawings.

[0031] The present disclosure provides a capping system for an inkjet printer. In particular, it provides a capping system for a thermal inkjet printer that covers an array of nozzles to prevent the nozzles from drying out when the printer is not printing. The capping system provides a floating cover that provides a rigid surface to contact and seal the nozzle array when the printer is not printing.

[0032] exist figure 1 A first embodiment of the capping device 10 is shown in . The capping device 10 includes a receptacle or base 2...

Abstract

A capping device for an ink jet print head includes a base configured to receive an ink jet print head and a cap assembly attached to the base. The cap assembly is configured for sliding movement with respect to the base to provide a closed position of the cap assembly when the print head is not printing and an open position to allow for the ejection of ink from nozzles when the print head is printing. The cap assembly includes a cover support and a cover attached to the cover support in a generally planar relationship thereto. The cover is adapted to provide additional movement with respect to the cover support in a direction different from the sliding direction. The cover includes a rigid mating surface configured to engage a surface of the print head adjacent the nozzles.

Description

technical field [0001] The present disclosure relates to capping devices for inkjet printers. Background technique [0002] Thermal inkjet printers are commonly used to print on stationary substrates such as paper as well as objects such as cartons / cartons and other types of primary and secondary packaging that can be moved past a print head. A common problem with thermal inkjet printers is that when the printhead is not in use, the ink tends to dry out and clog the printhead's nozzles. A common solution to prevent this type of nozzle clogging is to use some type of capping device to seal the area around the nozzle. Existing devices often use non-contact, molded or machined pockets on the nozzle orifice. In these designs, the sump around the nozzle orifice needs to remain saturated / saturated with the fluid to stay dry, and any deviation from planarity between the cap and the sump allows air to enter the sump, which causes the fluid to change. dry out and lose printability...
