    • A bidirectional printer interface comprises a print monitoring controller provided for a host unit for controlling a printer connected to the host unit to monitor a print state; an analyzer provided for the printer for analyzing environment data for setting a print environment and print data; a storage provided the printer for analyzing storing the print data analyzed by the analyzer; wherein the analyzer compares data in relation to a print environment included in the print data with the environment data stored in the storage to determine the presence of the difference therebetween, and if the difference between the data is detected, the analyzer transmits the content of the difference between the data to the host unit and wherein the printer monitoring controller notifies the user of the content of the difference between the data transmitted from the analyzer.
    • 双向打印机接口包括:打印监视控制器,用于主机单元,用于控制连接到主机单元的打印机以监视打印状态; 为打印机提供分析器,用于分析用于设置打印环境和打印数据的环境数据; 存储器提供用于分析存储由分析器分析的打印数据的打印机; 其中所述分析器将与打印数据中包括的打印环境相关的数据与存储在存储器中的环境数据进行比较,以确定其间存在差异,并且如果检测到数据之间的差异,则分析仪发送 数据与主机单元之间的差异,并且其中打印机监控控制器向用户通知从分析器发送的数据之间的差异。

    • An image forming apparatus has a photosensitive member for carrying an image, an exposure device for exposing the photosensitive member to form a latent image on the same, a development device for developing the latent image on the photosensitive member with a toner to form a toner image, a transfer member carrier for supporting and conveying a transfer member to a transfer position on the phtosensitive member, a first conveyance mechanism for conveying the transfer member to the transfer carrier member, and a second conveyance mechanism for conveying the transfer member to the first conveyance mechanism. A cancellation mechanism is provided to cancel a transfer member conveying force of the first conveyance mechanism after a leading end of the transfer member conveyed by the first conveyance mechanism has been supported on the transfer member carrier. A trailing end of the transfer member passes through a nip of the second conveyance mechanism during a period of time when the transfer member conveying force of the first conveyance mechanism is canceled by the cancellation mechanism and when the exposure device is not operating. In this arrangement, vibration generated when the transfer member is conveyed to the transfer member carrier by the first and second conveyance mechanisms is prevented from affecting the latent image formation made by the exposure device.
    • 图像形成装置具有用于承载图像的感光构件,用于曝光感光构件以在其上形成潜像的曝光装置,用于利用调色剂使感光构件上的潜像显影以形成调色剂图像的显影装置 ,用于将转印构件支撑并传送到感光构件上的转印位置的转印构件载体,用于将转印构件输送到转印承载构件的第一输送机构和用于将转印构件输送到第一输送器的第二输送机构 机制。 提供一种取消机构,用于在由第一输送机构输送的转印部件的前端已经被支撑在转印部件载体上之后取消第一输送机构的转印部件的输送力。 转印部件的后端在第一输送机构的转印部件输送力被取消机构取消并且曝光装置不工作的期间通过第二输送机构的辊隙。 在这种布置中,防止了通过第一和第二传送机构将传送部件传送到传送部件载体时产生的振动影响由曝光装置形成的潜像形成。
