Abstract
A wiper for a maintenance station of an imaging device includes a foundational body and a flexible blade. The body rigidly attaches to the maintenance station. The blade attaches to the body. The blade scrapes fluid and debris from a printhead during use. The blade comprises a flexible material having terminal sections intervened by a central section. Each terminal section connects to the body with a thicker expanse of flexible material, whereas the central section connects to the body with a thinner expanse. The connection provides the terminal sections with a higher wiping force and a shorter effective beam length for wiping an encapsulant of the printhead and gives while the central section a lower wiping force and a longer effective beam length for wiping a nozzle plate of the printhead. The embodiments note curved surfaces with variable radiuses where the expanses of flexible material connect to the body.
