Abstract: A recording system includes a first recording unit, including a recording module having a recording head and a cleaning unit which cleans the recording head, a conveying section which conveys a recording medium, and at least a second recording unit provided at a downstream side in a conveying direction of the recording medium, wherein the first recording unit records a first image portion and the second recording unit records a second image portion.

Abstract: In a printing system including a plurality of inkjet printing units and an ink tank commonly used thereby, wherein the ink tank is capable of notifying an amount of ink consumed thereby and has a memory for storing information relating to the ink consumption amount in a updatable manner, the memory access by the printing units is properly arbitrated. The printing system is provided with a storage section for storing the ink consumption amount notified from the respective printing units, a process section for reading the information from the memory and carrying out the calculation together with the stored ink consumption amount, a process section for updating the content in the memory based on the calculated value, and a process section for suspending the calculation relating to the amount of ink consumption in one printing unit, when the calculation is being carried out about any other printing units.

Abstract: An inkjet recording device according to the present invention performs preliminary ejection, not at an interval of fixed time but at a time detected by the inkjet recording device, to reduce the number of preliminary ejection for high-quality image recording or to reduce the number of preliminary ejection and the required time for higher throughput and faster image recording. A setting data count unit 1009 counts the number of occurrences of consecutive count patterns predetermined for each nozzle block according to the count patterns that are set in a preliminary ejection setting unit 1008 and the analysis result of the command analysis unit 1003. A preliminary ejection control unit checks, for each block, if the count value has reached a predetermined value and, if the count value has reached the predetermined value in at least one block, starts preliminary ejection for the recording head.

Abstract: The invention provides a recording system including a first recording unit including recording modules, each having a recording head and cleaning means which cleans the recording head, in plural units along a direction of width of a recording medium, conveying means which conveys the recording medium, and at least a second recording unit provided at a downstream side in a conveying direction of the recording medium, wherein the first recording unit records a first image portion and the second recording unit records a second image portion.

Abstract: An inkjet recording device according to the present invention performs preliminary ejection, not at an interval of fixed time but at a time detected by the inkjet recording device, to reduce the number of preliminary ejection for high-quality image recording or to reduce the number of preliminary ejection and the required time for higher throughput and faster image recording. To do so, with a sequence of nozzles of a recording head divided into plurality of nozzle blocks each composed of a plurality of nozzles, a command analysis unit 1003 analyzes recording data. A setting data count unit 1009 counts the number of occurrences of consecutive count patterns predetermined for each nozzle block according to the count patterns that are set in a preliminary ejection setting unit 1008 and the analysis result of the command analysis unit 1003.
