International Classification:

G03G 15/10

US Classification:

399237

Abstract:

In one embodiment, an image developer includes a developer roller rotatable along a photoconductor for presenting a layer of ink to the photoconductor and a cleaner for cleaning ink from the developer roller. The cleaner includes a first cleaning roller rotatable along the developer roller for removing ink from the developer roller and a second cleaning roller rotatable against the first cleaning roller for mechanically removing ink from the first cleaning roller. In one embodiment, the second cleaning roller deforms against the first cleaning roller such that the cross-sectional length of contact between the first and second cleaning rollers is in the range of 20% to 38% of the circumference of the first cleaning roller. In one embodiment, the second cleaning roller has a density in the range of 90 kg/mto 150 kg/m.

Assignee:

Hewlett-Packard Development Company, L.P. - Spring TX

International Classification:

G03G 15/08

Abstract:

In one example in accordance with the present disclosure, a developer unit seal is described. The seal includes a first sealing member to contact an end cap of the developer unit. The first sealing member has ports to align with rollers that are to protrude into the end cap. The seal includes a second sealing member to contact the first sealing member. The second sealing member has ports to align with the rollers. Channels are disposed between the first sealing member and the second sealing member to direct print fluid to each of the ports.

International Classification:

G03G 15/10
G03G 15/16
G03G 15/20

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.
