摘要： An imaging apparatus is provided including a frame having a portion upon which a printhead is adapted to be mounted. The printhead may include a housing including a main body, at least one flexible mounting beam extending from the main body, and at least one structural member coupled to the at least one flexible mounting beam. The printhead may also include a skew correction mechanism mounted to the printhead housing. The skew correction mechanism may include an adjustment member capable of engaging at least one surface on the printhead housing so as to adjust the position of the printhead housing relative to the frame portion.

摘要： A laser scanning unit is provided comprising: a housing; a scanning device; a first pre-scan assembly generating a first light beam and directing the first light beam toward the scanning device; a second pre-scan assembly generating a second light beam and directing the second light beam toward the scanning device; a first post-scan assembly receiving the first light beam reflected from the scanning device and causing a first portion of the first light beam to scan along a first scan path; and a second post-scan assembly receiving the second light beam reflected from the scanning device and causing a first portion of the second light beam to scan along a second scan path. The first post-scan assembly further reflects a second portion of the first light beam in a direction away from the first scan path. A shield is associated with the housing for blocking the second portion of the first light beam reflected by the first post-scan assembly during at least a portion of the scan of the first portion of the first light beam along the first scan path so as to prevent the second portion of the first light beam from entering the second post-scan assembly.
摘要翻译：提供了一种激光扫描单元，包括：壳体; 扫描装置; 产生第一光束并将第一光束引向扫描装置的第一预扫描组件; 产生第二光束并将第二光束引向扫描装置的第二预扫描组件; 第一后扫描组件，其接收从所述扫描装置反射的所述第一光束，并使所述第一光束的第一部分沿着第一扫描路径扫描; 以及第二后扫描组件，其接收从所述扫描装置反射的所述第二光束，并使所述第二光束的第一部分沿着第二扫描路径扫描。第一后扫描组件进一步沿远离第一扫描路径的方向反射第一光束的第二部分。屏蔽件与壳体相关联，用于在沿第一扫描路径的第一光束的第一部分的扫描的至少一部分期间阻挡由第一后扫描组件反射的第一光束的第二部分，从而防止第一光束的第二部分进入第二后扫描组件。
