摘要： A method and a device for detecting ink leakage during a printing process are used in an inkjet printing machine including a workflow system on a computer for print job control, an ink supply unit including an ink reservoir with an ink level sensor, a control unit running software for controlling the ink supply and print heads capable of creating ink drops of different sizes. A theoretical amount of ink to be consumed is calculated based on prepress printing data by adding drop volumes using the workflow system. The theoretical amount to be consumed is transmitted to the ink supply control software using the workflow system. An actual amount of ink having been consumed is detected by the ink level sensor. The theoretical ink consumption amount and the actual ink consumption amount are compared and a leakage alert is displayed if the actual amount is greater than the theoretical amount.

摘要： An inkjet recording apparatus includes an ink tank, a recording head, an ink sensor, a monitor, an operation panel, and a controller configured to control operation thereof. The controller receives a completion signal indicating completion of ink injection, and receives a first signal or a second signal from the ink sensor based on whether a predetermined amount of ink is sensed in the ink chamber. Based on the completion signal and receipt of the first signal, inquiry information is displayed on the monitor regarding whether ink injection into the ink chamber is completed. Based on the completion signal and receipt of the second signal, a notification is displayed on the monitor that is based on the ink sensor not sensing the predetermined amount of ink.

摘要： A liquid consumption device includes a replaceable liquid container, a sensor, a fault finding section, an estimation section and a determination section. The sensor detects whether or not liquid has reached a predetermined amount. The fault finding section finds whether there is a fault in the sensor. The estimation section calculates an estimated value of a consumption amount of the liquid. The determination section carries out determination based on the estimated value of the liquid container and a threshold value which is specified based on threshold value information when a fault in the sensor has been found. The determination section carries out the determination based on the sensor when a fault in the sensor has not been found and to calculate the threshold value information based on the estimation value when the sensor detects that the liquid has reached the predetermined amount.

摘要： A drop in the throughput of continuous printing operations caused by refilling a subtank with ink is suppressed. The control unit of an inkjet printer 1 fills subtanks 11a-11d with ink whenever ink consumption exceeds a reference volume q during continuous printing. Ink is suctioned by producing negative pressure in subtanks 11a-11d during the ink refill operation while ink continues being supplied to the inkjet head 7 from pressure adjustment chambers 13a-13d disposed between subtanks 11a-11d and inkjet head 7. Ink ejection from the inkjet head 7 can therefore continue even during the ink refill operation. By setting the volume of the pressure adjustment chambers 13a-13d greater than at least the amount of ink that is ejected during the ink refill operation, there is no need to interrupt printing in order to replenish the ink supply.
