Inkjet printhead protection apparatus
Some embodiments of a protector apparatus for protecting a printhead having a nozzle plate include a protection layer, a spacer layer, a flexible magnetic layer having a first surface and a second surface opposing the first surface, and a handle connected to one end of the flexible magnetic layer. The spacer layer is sandwiched between the protection layer and the first surface of the flexible magnetic layer. The handle is connected to the second surface of the flexible magnetic layer. The protector apparatus can be magnetically attached to the printhead in such a manner that the first protection layer covers the nozzle plate.
1. A protector apparatus for protecting a printhead having a nozzle plate, the protector apparatus comprising:
a protection layer;
a spacer layer;
a flexible magnetic layer having a first surface and a second surface opposing the first surface; and
a handle connected to one end of the flexible magnetic layer,
wherein the spacer layer is sandwiched between the protection layer and the first surface of the flexible magnetic layer such that the spacer layer is interposed between the protection layer and the first surface of the flexible magnetic layer,
wherein the handle is connected to the second surface of the flexible magnetic layer, and
wherein the protector apparatus can be magnetically attached to the printhead in such a manner that the first protection layer covers the nozzle plate.
2. The protector apparatus of claim 1 , wherein the protection layer is a plastic foil.
3. The protector apparatus of claim 1 , wherein the handle has a flexible body.
4. The protector apparatus of claim 1 , wherein the handle is composed of plastic or fabric.
5. The protector apparatus of claim 1 , wherein the spacer layer is composed of an adhesive that bonds the protection layer to the flexible magnetic layer.
6. The protector apparatus of claim 1 , wherein the spacer layer is composed of a low-durometer material.
7. The protector apparatus of claim 1 , wherein the flexible magnetic layer includes one or more flexible magnets.
8. The protector apparatus of claim 1 , wherein the flexible magnetic layer includes a plurality of rigid magnets with flexible joints therebetween that allow the flexible magnetic layer to bend at the flexible joints.
9. A protector apparatus for protecting a printhead having a nozzle plate, the protector apparatus comprising:
a flexible magnetic layer having a first side, a second side opposing the first side, and a perimeter, wherein the flexible magnetic layer has a platform that lies along the perimeter of the first side to define a depression in a central portion of the first side;
a protection layer, wherein the protection layer is positioned on the platform; and
a handle connected to one end of the protector apparatus,
wherein the platform and the cavity are sized such that, when the platform contacts a printhead, a nozzle plate of the printhead does not contact the platform.
10. The protector apparatus of claim 9 , further comprising:
a spacer layer that is sandwiched between the protection layer and the flexible magnetic layer.
11. The protector apparatus of claim 9 , wherein the handle is connected to the second side of the flexible magnetic layer.
