Abstract

An apparatus and method for cleaning liquid developer from reusable surfaces used for carrying latent electro~ static images is described~ Dual elements comprising a wiper blade and a rotatable absorbent roller or belt in contact with either a reusable photoconductor or a reusable interposition surface remove residual liquid developer and solid matter including lint, dust and paper fibers from the surface so that the surface can be reused without inter~ ference from streaks or residual layers of developer remaining from previous cycles. Means are provided for

CLEANING OF INKED SURFACES (Cont~d)

removing accumulated developer from the absorbent roller or
belt.

As illustrated in Figure 1, reusable cylindrical photocon~
ductor surface 1 having liquid developer 6 thereon is first

contacted with wiper blade 2 leaving residual liquid devel~
oper 7 on surface 1. Rotatable roll of absorbent material
13 in contact with surface 1 downstream from wiper blade 2
removes residual liquid developer 7 from surface 1. In
Figure 2, there is shown a similar cleaning station wherein
liquid developer 6 is cleaned from reusable interposition
web or surface 10 comprising, e.g., a polyester film or a
polyvinylfluoride film. Preferred wiper blades are resilient

and can be rubber or polyurethan...
