摘要： A remaining toner amount detecting apparatus detects a remaining toner amount in a toner bottle. The remaining toner amount detecting apparatus includes at least one pair of electrodes that are configured to face each other with the toner bottle interposed between the electrodes; a first estimator configured to estimate the remaining toner amount based on a capacitance between the electrodes of the at least one pair of electrodes; a second estimator configured to estimate the remaining toner amount by counting a number of pixels in a printed image; and an estimation selector configured to use either one of the first estimator or the second estimator to output the remaining toner amount, based on a temperature or a humidity inside an apparatus in which the toner bottle is mounted.

摘要： An inkjet recording apparatus includes a plurality of line heads disposed along a conveyance direction of a recording sheet and including a plurality of nozzles to discharge ink droplets, the plurality of nozzles disposed in a direction perpendicular to the conveyance direction of the recording sheet; a plurality of edge sensors corresponding to respective line heads, to detect a lateral edge of the recording sheet; a plurality of actuators corresponding to the respective line heads, to move to the respective line heads laterally in a sheet width direction; a head position adjustor to determine movement amounts of the respective line heads in accordance with outputs of the plurality of edge sensors; and a failure determiner to obtain outputs of the plurality of edge sensors simultaneously and identify a failure of the plurality of edge sensors based on a combination of the outputs from the plurality of edge sensors.
