Abstract: Certain examples relate to mixing and/or supply cartridges for printing apparatus. One example implementation includes a reservoir to receive printing material from a printing apparatus and to return the received printing material to the printing apparatus. A storage medium stores a reservoir printing material level parameter indicative of the amount of printing material in the reservoir; a recirculation cycle counter indicative of the number of recirculation events experienced by the cartridge; a maximum recirculation cycle parameter indicative of the maximum number of recirculation events that may be experienced by the cartridge.

Abstract: A control system for controlling actuators comprises a central processor, a plurality of actuators, and a plurality of servo systems for controlling the respective actuators. Each servo system is operable, independently of the central processor, to control a controlled parameter (Y) in accordance with a reference value (R). The servo systems and the central processor communicate via a non-deterministic communications system. The central processor and the servo systems provide, to the central processor via the non-deterministic communications system, offset signals representing offsets (R−Y) measured by the servo systems between reference R and actual Y values of the controlled parameter. The central processor compares the offsets (R−Y) measured by the respective servo systems one with another.
Abstract translation: 用于控制致动器的控制系统包括中央处理器，多个致动器以及用于控制各个致动器的多个伺服系统。 每个伺服系统可独立于中央处理器操作，以根据参考值（R）控制受控参数（Y）。 伺服系统和中央处理器通过非确定性通信系统进行通信。 中央处理器和伺服系统通过非确定性通信系统向中央处理器提供偏移信号，表示伺服系统在参考R和受控参数的实际Y值之间测量的偏移（R-Y）。 中央处理器将由相应的伺服系统测量的偏移（R-Y）与另一个相比较。

Abstract: Certain examples relate to controlling recirculation processes in a printing apparatus. An example printing material cartridge includes a reservoir storing printing material to supply a printing apparatus; memory; and instructions for controlling a recirculation process in the printing apparatus, the instructions stored in the memory, the recirculation process to cause the printing material to move between the reservoir and a second printing material cartridge, the second printing material cartridge separately replaceable from the printing material cartridge in the printing apparatus.

Abstract: Operating a fluid delivering system in a printer, wherein the fluid delivering system comprises a fluid supply including a fluid bag which contains a fluid to be delivered to a fluid delivering tube connected to a printhead, and a closed pressurizing volume which surrounds the fluid bag to expel fluid from the fluid bag to the fluid delivering tube when applying pressure from a pressurizing system to the pressurizing volume, wherein pressure in the pressurizing system relative to atmosphere is measured by a first sensor, and wherein a second sensor provides an output signal which indicates a pressure difference between the pressurizing system and the fluid delivering tube, comprising disconnecting the pressurizing volume of the fluid supply from the pressurizing system, providing a connection of the pressurizing volume to atmosphere to transmit atmospheric pressure to the fluid, generating pressure in the pressurizing system, performing measurements of the pressure in the pressurizing system relative to atmosphere by the first sensor, and calibrating the second sensor by the measurements of the first sensor.
