    Abstract: A media transport system provides full vacuum under media as the media traverses an entire print path of an ink jet printer while simultaneously providing for a no-vacuum inter-copy gap that moves along with the media past print heads of the ink jet printer. This is accomplished with a dual vacuum inner/outer vacuum drum system that includes a first drum that has a matrix of holes that allows for full coverage of vacuum with a second underlying drum that is shifted to align a second set of holes to match the sheet pitch. By shifting the second drum in relation to the first drum, a combination set of holes is aligned to provide full vacuum across the media while a column of holes is blocked to provide a non-vacuum inter-copy gap.

    Abstract translation: 当介质穿过喷墨打印机的整个打印路径时，介质传送系统在介质下提供完全真空，同时提供与介质一起沿着喷墨打印机的打印头移动的无真空复印间隙。 这是通过双重真空内/外真空鼓系统实现的，该双真空内/外真空鼓系统包括具有孔矩阵的第一鼓，所述第一鼓允许用第二下面的鼓全面覆盖真空，该第二底鼓被移动以对准第二组孔以匹配片 沥青。 通过相对于第一滚筒移动第二滚筒，对齐一组组合的孔，以便跨过介质提供全真空，同时一列孔被阻挡以提供非真空的间隙间隙。

    Abstract: A self-adjusting clamp mechanism prevents sheets from migrating back during the compiling of sheets in a stacker. The mechanism consists of a spring-loaded ball bearing in a converging track placed just before a registration wall. The sheets would be scuffed under the ball bearing and against the registration wall. The track converges away from the registration wall such that: it allows sheets to enter freely against the registration wall; exerts little resistance for side tamping; and prevents the sheets from moving away from the registration wall as the ball bearing is driven tighter into the converging track.

    Abstract translation: 自动调整夹紧机构可以防止纸张在堆叠器中的纸张编制过程中向后移动。 该机构由刚刚在配准壁之前的会聚轨道中的弹簧加载的球轴承组成。 这些片材将被磨损在球轴承下方并抵靠在对准壁上。 轨道远离注册墙，从而允许纸张自由地抵靠对准墙; 对侧面夯实施加很小的阻力; 并且当滚珠轴承被更紧密地进入会聚轨道时，防止纸张离开配准壁。
