摘要： A developer unit usable with a liquid electrophotographic printing apparatus having a photosensitive drum includes a developer roller configured to receive ink, and to selectively engage and rotatably transfer the ink to the photosensitive drum, the developer roller configured to switch between a contact mode when the developer roller is rotating and a non-contact mode when the developer roller is not rotating, a squeegee roller selectively in contact with the developer roller, the squeegee roller configured to at least condense the received ink on the developer roller in the contact mode, and configured to be apart from the developer roller in the non-contact mode, and a cleaner roller selectively in contact with the developer roller, the cleaner roller configured to remove remaining ink from the developer roller not transferred to the photosensitive drum in the contact mode, and to be apart from the developer roller in the non-contact mode, wherein at least one of the squeegee roller, the cleaner roller and the developer roller are configured to move between the contact mode and the non-contact mode in response to a rotational state of the developer roller.

摘要： A sealing device usable with an ink developer unit including a plurality of rollers and a plurality of end cap members includes a first replaceable compliant sealing member and a latch member. The first replaceable compliant sealing member has a plurality of replaceable seal exterior surfaces to form a seal between a first set of rollers of the plurality of rollers and one of the end cap members. The latch member has a closed state to maintain a sealing force on the first replaceable compliant sealing member and an open state to remove the sealing force on the first replaceable complaint sealing member.

摘要翻译： 可用于包括多个辊和多个端盖构件的油墨显影单元的密封装置包括第一可替换的柔性密封构件和闩锁构件。 第一可替换的柔性密封构件具有多个可更换的密封外表面，以在多个辊的第一组辊和一个端盖构件之间形成密封。 闩锁构件具有闭合状态，以保持第一可更换顺应性密封构件上的密封力，并且打开状态以去除第一可更换投诉密封构件上的密封力。
