LEP printer, a photo imaging plate for such printer and a method for wiping such photo imaging plate

摘要

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.

主权项

1. 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.
