Abstract
A method for wiping a printhead of an inkjet printing mechanism is provided. The printhead surface defines a printhead plane. In the method, firstly a wiper is moved substantially parallel to the printhead plane for wiping a first portion of the printhead surface. After the first portion of printhead surface is wiped, the wiper is moved away from the printhead plane for wiping a second portion of the printhead surface.
Claims10
A method for wiping a printhead having a surface of an inkjet printing mechanism, wherein the printhead surface defines a printhead plane, the method comprising:
- moving a wiper substantially parallel to the printhead plane for wiping a first portion of the printhead surface;
- and
- after wiping the first portion of the printhead surface, moving the wiper at a degree to the printhead plane for wiping a second portion of the printhead surface.
A method for wiping a printhead having a surface of an inkjet printing mechanism, wherein the printhead surface defines a printhead plane, the method comprising:
- moving a wiper substantially parallel to the printhead plane for exerting a first amount of wiping force on the printhead to wipe a first portion of the printhead surface;
- and
- after wiping the first portion of the printhead surface, moving the wiper away from the printhead plane for exerting a reduced amount of wiping force on the printhead to wipe a second portion of the printhead surface.
A wiper assembly for wiping a printhead having a surface in an inkjet printing mechanism having a chassis, with the printhead on a carriage supported by the chassis for moving to a wiping position, and with the printhead surface defining a printhead plane, the assembly comprising:
- a frame which defines a first and second guide tracks connected thereto, wherein the first track extends substantially parallel to the printhead plane, and wherein the second track extends away from the printhead plane;
- a platform movable along the tracks;
- and
- a wiper mounted on the platform for wiping the printhead when the printhead is in the wiping position.
An inkjet printing mechanism, comprising:
- a chassis;
- a printhead having a surface on a carriage supported by the chassis for moving to a wiping position, the printhead surface defining a printhead plane;
- and
- a wiper assembly including
- a frame which defines a first and a second guide tracks connected thereto, wherein the first track extends substantially parallel to the printhead plane, and wherein the second track extends away from the printhead plane;
- a platform movable along the tracks;
- and
- a wiper mounted on the platform for wiping the printhead when the printhead is in the wiping position.
A method for wiping a printhead having a surface of an inkjet printing mechanism, wherein the printhead surface defines a printhead plane, the method comprising:
- moving a wiper in a first direction substantially parallel to the printhead plane for wiping a first portion of the printhead surface;
- and
- after wiping the first portion of the printhead surface, moving the wiper in the first direction while simultaneously rotating the wiper in a second direction about an axis for wiping a second portion of the printhead surface.
