Abstract

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.
