Abstract:
A drying apparatus which dries a medium on which an image is formed with ink while conveying the medium includes a conveyance part, a heating part, a measurement part and a controller. The conveyance part conveys the medium in a predetermined conveyance direction. The heating part supplies energy to the image on the sheet conveyed in the conveyance part and dries the image. The measurement part measures a value accompanied with moisture contained in the medium. The controller estimates an amount of moisture contained in the medium based on the value measured by the measurement part, and controls at least one of the conveyance part and the heating part so as to change an amount of the energy supplied to the image based on the estimated amount of moisture.

The control device causes the display device, upon deciding that the color of received light accords with an allocated color, with respect to all of the plurality of light receivers, to display a first message, and causes the display device, upon deciding that the color of received light discords with the allocated color, with respect to at least one of the plurality of light receivers, to display a second message.
Abstract:
A fullness detection device includes a waste toner collecting portion, a waste toner container configured to store the collected waste toner, the waste toner container has translucency, a detecting portion including a light emitting portion and a light receiving portion disposed to sandwich the waste toner container, the light receiving portion receiving the light from the light emitting portion, and a determining portion configured to determine whether or not the waste toner container is full based on whether or not an output value of the light receiving portion is higher than a predetermined threshold value. The light emitting portion increases light intensity step by step and emits light at a level of smallest light intensity among light intensity levels at which it is determined that the waste toner container is not full.
Abstract:
An electronic apparatus includes a drive unit having a drive roller, a driving motor, and a limited-life component, a sound collecting device that collects sound from the limited-life component, and outputs sound data, a storage device storing in advance a sound pressure level corresponding to a specific frequency of the limited-life component, with respect to each of different lengths of the remaining service life, and a controller that analyzes frequency of the sound data at predetermined time points; acquires the sound pressure level corresponding to the specific frequency of the limited-life component, on a basis of a result of the frequency analysis; compares the acquired sound pressure level with the sound pressure level of each of the lengths of the remaining service life; predicts the remaining service life of the limited-life component, on a basis of comparison result; and displays the predicted remaining service life on a display device.
Abstract:
An image forming apparatus includes an image forming section, a content fraction calculating section, and an information storage section. The content fraction calculating section calculates a content fraction of each of a plurality of toners contained in the image forming section that have been supplied from different toner cartridges to one another. The information storage section stores therein, for each of the toners, a control value that is used to control a component of the image forming section. The image forming section forms an image based on respective content fractions of the toners and respective control values for the toners.
Abstract:
In an image reading device, a movable part provided below a document platen in a housing is moved in a sub scanning direction. A reflection control part extending along a movement range of the movable part is fixed to the housing near the movable part. The reflection control part has first reflection parts having a relatively large reflectance and second reflection parts having a relatively small reflectance arranged along the movement range. A detection light irradiation part provided in the movable part irradiates the reflection control part with detection light. A detection light reception part receives the detection light reflected by the reflection control part. A signal generating part generates a binary signal corresponding to the detection light received by the detection light reception part. A movement deciding part decides movement state of the movable part according to the binary signal generated by the signal generating part.
Abstract:
An image forming apparatus includes an image forming device, a transport belt, an optical sensor, an ultrasonic sensor, and a controller. The transport belt transports the recording sheet. The optical sensor emits light to the transport belt, and receives the light reflected by the transport belt. The ultrasonic sensor transmits ultrasonic wave to the transport belt, and receives the ultrasonic wave transmitted through the transport belt. The controller decides whether an output from each of the optical sensor and the ultrasonic sensor represents a normal value or an abnormal value, and executes predetermined control, depending on a combination of decision results about the respective outputs from the optical sensor and the ultrasonic sensor.
Abstract:
A liquid leakage detection device includes a first absorption layer, a second absorption layer, and a pair of terminals. The first absorption layer absorbs liquid. The second absorption layer is stacked on the first absorption layer, and absorbs the liquid. The pair of terminals are in contact only with the second absorption layer.
Abstract:
An image reading device includes a light source, an imaging section, and a controller. The light source includes a plurality of light emitting elements. The light source irradiates light to an original document, while moving relative to the original document. The imaging section obtains scan data read from the original document by light irradiated to the original document from the light source. The controller controls the light source and the imaging section. The controller determines a read target region and a non-read target region in the original document, turns on a light emitting element out of the plurality of light emitting elements, which corresponds to the read target region, and turns off a light emitting element out of the plurality of light emitting elements, which corresponds to the non-read target region.
Abstract:
The forced light emission detection unit detects a forced laser beam emission state of an exposing unit when the exposing unit starts forming a latent image on a photosensitive drum. The toner transfer control unit performs the developing of the electrostatic latent image formed at a position before the electrostatic latent image on which the forced laser beam emission state is detected, and transfers the developed toner image to a sheet. The sheet re-conveyance unit makes the sheet being in a re-conveyance state using a duplex printing conveyance path. The toner re-transfer control unit reforms the electrostatic latent image formed after the position on which the force laser beam emission state is detected, performs the developing of the electrostatic latent image, and transfers the developed toner image to the sheet in the re-conveyance state.
