    Abstract: A drive circuit of a recording head having a recording element is provided. The drive circuit supplies a load element for recording operation of the recording element with an output signal of electric power according to operation of the load element. The drive circuit includes a voltage amplifier that amplifies a voltage of an analog drive waveform signal for operation of the recording element to generate a drive voltage signal. The voltage amplifier includes amplifiers. Among the amplifiers, at least one of subsequent-stage amplifiers which are a second and subsequent amplifiers from an upstream side includes a signal feedback unit that returns a signal to be output to an input side of the subsequent-stage amplifiers.

    Abstract: Provided is an information processing apparatus capable of preventing erroneous detection of an abnormality even in a case where a region other than an inspection target region appears in an image of an object or even in a case where the appearance of the object may partially vary because of the nature of the object. An information processing apparatus includes: a generating section that acquires an image and generates a reconstructed image based on the image; an identification section that identifies an inspection target region in the image based on the image; and a calculation section that calculates a difference in the inspection target region between the image and the reconstructed image.

    CPC classification number: G03G15/205

    Abstract: An image forming apparatus including: an image former that forms an image on a recording material; includes a fixer that has a first fixing member having an elastic layer, a second fixing member that forms a fixing nip with the first fixing member, and an external heater that heats the first fixing member from outside, and fixes the image on the recording material by heating and pressing the conveyed recording material at the fixing nip; and a hardware processor that executes a thermal expansion mode, in which in the thermal expansion mode, the hardware processor causes the external heater to heat the first fixing member to a temperature higher than a temperature during normal printing.

    Abstract: An inkjet recording device including: inkjet head having a pressure chamber; a first pressure source to adjust ink energy per unit volume to generate “energy per unit volume” P1(Pa) relative to static ink at an atmospheric pressure at a nozzle opening height; a second pressure source to adjust ink energy per unit volume to generate “energy per unit volume” P2(Pa) relative to static ink; and a hardware processor. The first pressure source, pressure chamber, and second pressure source are connected in this order by a flow path. Assuming that a pressure loss occurring from the first pressure source to the nozzle due to circulation flow rate is ΔPa, a proportionality constant of a differential pressure (P1−P2) and ΔPa is “a”, and an appropriate pressure in vicinity of the nozzle opening is Pn, the hardware processor controls pressure to establish P2={Pn−(1−a)P1}/a.
