  • Maintaining layer of cleaning solution on photoconductive surface via wiper with purposefully rounded edge
    Patent number: 11067939
    Abstract: A cleaning solution is used to at least substantially remove colorant from the photoconductive drum as the photoconductive drum rotates. A wiper wipes the cleaning solution from the photoconductive drum while purposefully maintaining a layer of the cleaning solution on the drum. The wiper has an edge that is purposefully rounded.
    Type: Grant

  • Method and apparatus for reducing contamination in liquid electrophotographic printing
    Patent number: 10908520
    Abstract: In an example of a method for reducing contamination, a purified imaging oil is formed by filtering an imaging oil through an imaging oil filter, and then filtering the imaging oil through a polar absorbent filter. A surface of an amorphous silicon photoconductor of a liquid electrophotographic printing apparatus is maintained by periodically applying the purified imaging oil to the amorphous silicon photoconductor.
