US 10,877,402 B2 · Print agent application assemblies

Abstract

In an example, a print agent application assembly includes a print agent transfer roller to receive print agent and transfer a portion of the print agent to a photoconductive surface and a print agent regulator roller to regulate a film thickness of print agent on the print agent transfer roller. The print agent regulator roller may include a nip forming region and a first mounting region. The print agent application assembly may further include a first resilient component which spans a diametrical width of the print agent regulator roller and acts on the print agent regulator roller outside the nip forming region to impart a lateral force to the first mounting region, the lateral force urging the print agent regulator roller towards the print agent transfer roller.

Dependent claims

A print agent application assembly comprising:

a print agent transfer roller to receive print agent and transfer a portion of the print agent to a photoconductive surface;
a print agent regulator roller to regulate a film thickness of print agent on the print agent transfer roller, the print agent regulator roller comprising a nip forming region and a first mounting region including an axle region at which an axle of the print agent regulator roller is exposed;
and
a first resilient component, which spans a diametrical width of the print agent regulator roller and acts on the print agent regulator roller outside the nip forming region and outside the axle region of the first mounting region to impart a lateral force to the first mounting region outside the axle region, the lateral force urging the print agent regulator roller towards the print agent transfer roller.

A method comprising:

mounting a print agent transfer roller in a print agent application assembly housing;
mounting a print agent regulator roller in the print agent application assembly housing so as to form a nip in a nip forming region thereof interior to a first mounting region including an axle region at which an axle of the print agent regulator roller is exposed;
and
attaching a first resilient component to the print agent application assembly housing between a first mounting point on a first side of the print agent regulator roller and a second mounting point on a second side of the print agent regulator roller so as to span a diametrical width of the print agent regulator roller and to urge the print agent regulator roller toward the print agent transfer roller by applying pressure thereto outside the nip forming region and outside the axle region of the first mounting region.
