Abstract
In an LEP printer having a wiper blade for wiping a photo imaging plate, the photo imaging plate may include a PIP foil with a trailing edge having a zone of a roughening pattern which includes notches that are inclined with respect to a contact line of the wiper blade. The zone of roughening pattern is confined between two opposite margins lacking any roughening.
Claims19
A method comprising:
- providing a wiper blade in a liquid electro-photographic (LEP) printer;
- and
- arranging a photo imaging plate that is to be wiped by the wiper blade in the LEP printer, the photo imaging plate comprising a photo imaging plate foil that includes a photoconductive material and a trailing edge portion having a zone of a roughening pattern which includes notches created by heating the zone to a specified temperature during a process in which the notches are being formed, each of the notches having a length that extends across a width of the photo imaging plate foil, where the length of each of the notches is inclined at an angle with respect to a contact line of the wiper blade, the angle greater than zero degrees and smaller than 10 degrees, and the zone of roughening pattern confined between two opposite margins lacking any roughening.
A method for forming a photo imaging plate foil of a photo imaging plate of a liquid electro-photographic (LEP) printer, the method comprising:
- forming on a trailing edge portion of the photo imaging plate foil a zone of a roughening pattern which includes notches each having a length that extends across a width of the photo imaging plate foil that comprises a photoconductive material, where the length of each of the notches is inclined at an angle with respect to a contact line of a wiper blade, the angle greater than zero degrees and smaller than 10 degrees, and the zone of roughening pattern confined between two opposite margins lacking any roughening;
- and
- heating, to a specified temperature, the zone of roughening pattern in the photo imaging plate foil during a process in which the notches are being formed.
A photo imaging plate for use in a liquid electro-photographic (LEP) printer having a wiper blade, comprising:
- a photo imaging plate foil including a photo conductor and a trailing edge portion having a zone of a roughening pattern which includes notches created by heating the zone to a specified temperature during forming of the notches, each of the notches having a length that extends across a width of the photo imaging plate foil, where the length of each of the notches is inclined at an angle with respect to a contact line of the wiper blade that is for contacting and wiping a surface of the photo imaging plate, the angle greater than zero degrees and smaller than 10 degrees, and the zone of roughening pattern is confined between two opposite margins lacking any roughening.
