    Abstract: According to one example, there is provided a system for compensating for changes in printhead-to-printhead spacing in a printing system having multiple printheads mountable on a printhead support. The system comprises a measurement system to determine a change in printhead-to-printhead spacing between different ones of mounted printheads, and a processor to determine compensation to be applied to the printing system to compensate for the determined change in printhead-to-printhead spacing.

    Abstract translation: 根据一个示例，提供了一种用于补偿具有可安装在打印头支撑件上的多个打印头的打印系统中的打印头对打印头间隔的变化的系统。 该系统包括测量系统，用于确定不同安装的打印头之间的打印头对打印头间距的变化，以及处理器，用于确定要应用于打印系统的补偿以补偿确定的打印头到打印头间距的变化 。

    Abstract: A printing apparatus is disclosed. The printing apparatus comprises a rotating housing comprising a wall with an inner side defining a chamber and an outer side. The wall has a bore communicating the inner side and the outer side, and the chamber is to receive a fluid container. The printing apparatus also comprises a fix frame holding the rotating housing. The printing apparatus further comprises an optical sensor comprising an emitter to issue a detecting optical signal through the bore and a receiver to receive a detected optical signal associated to the detecting optical signal. The detected signal is sent to a controller to determine whether the fluid container is present in the rotating housing.

    Abstract: Devices and methods for calibrating communication lines are disclosed. A clock sets a frequency of transmission through a communication line. A delay compensator, comprising multi-tap delay lines introduces delays in a transmitted message to compensate for skew in the communication line. An error comparator, coupled to the delay compensator, identifies errors in the messages transmitted through the multi-tap delay lines above an error margin. A delay selector, coupled to the error comparator and to the delay compensator, selects taps of the multi-tap delay lines of the delay compensator. Taps of the multi-tap delay lines where no errors are identified for the selected clock frequency are stored in a memory.
