Abstract: The present inventions allow the detection of ink in the printing head by significantly simplified their configurations and on which various printing systems can be widely applied. There are a heater (101) for supplying an energy to ejecting ink, a driver (102) for driving heater (101), and a detection electrode (118) capable of detecting a voltage variation between the heater (101) and the driver (102) to be occurred depending on the driving of the heater (101). Furthermore, an insulating film (410) that covers the surface of the detection electrode (118) prevents a chemical or physical change from the detection electrode (118). Furthermore, a reference element group or a reference unit that produces a signal as a reference of the detection signal avoids the influence of noise. Furthermore, an energy-generating element (101) and another signal source (101) improve the accuracy of ink-detection. A drive pulse which is insufficient to ejecting ink may be supplied to the heater (101) to improve the accuracy of ink-detection.

Abstract: PROBLEM TO BE SOLVED: To detect the non-ejection state of a nozzle efficiently and certainly in a short time, and to cut back wasteful ink consumption amount in the case a nozzle is in the non-ejection state. SOLUTION: In the case the non-ejection state of a nozzle is detected, after executing a recovery process, detecting operation of the non-ejection state is executed again only for the nozzle with the non-ejection state detected.

Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recording device to suppress cockling of a recording medium and floating of a paper sheet through simple constitution and obtain an excellent recording image. SOLUTION: An ink jet recording device effects recording by discharging ink liquid drops from an ink jet recording head 1 toward a recording medium 8 to effect recording. A paper press plate 18 to form an uneven surface shape in the recording medium 8 in a direction crossing the conveying direction of the recording medium in a recording region and a platen 15 are disposed. Further, the stiffness strength of the recording medium 8 is detected by a contact part 32 and the press plate 18 is controlled by a contact control part 33.
