An image forming apparatus includes a sensor that acquires first and second data groups of paper characteristics by measuring a recording medium; a processor that determines a parameter for controlling at least one of image formation and conveyance of a recording medium on a conveyance path based on the first and second data groups acquired by the sensor; an image former that forms an image on a recording medium conveyed on the conveyance path based on the parameter. The processor compares the first and second paper characteristic data groups, the first paper characteristic data group has been measured at a first time period and the second paper characteristic data group has been measured at a second time period nearer to a present time than the first time period, and the processor controls the image formation based on a the comparison result.

Sheet product dispensers and methods are provided. A sheet product dispenser includes a loading station for sheet material, a sheet feeding mechanism configured to feed the sheet material, a presentation station for presenting one or more discrete sheet products to an end user, a sensor downstream of the feeding mechanism and upstream of the presentation station configured to detect a presence of the discrete sheet products, and a controller configured to facilitate dispensing of the one or more discrete sheet products in response to a signal, and to determine and store data associated with the dispensing of the sheet products.

A medium processing apparatus includes a liquid applier, a medium processing device, circuitry, and a freezing detector. The liquid applier applies liquid to a part of a medium to perform a liquid application. The medium processing device performs desired processing on a bundle of media including the medium subjected to the liquid application. The circuitry controls the liquid application and the desired processing. The freezing detector notifies the circuitry of freezing information including a frozen state of the liquid. The circuitry selects, based on the freezing information, one of first processing that is the desired processing performed on the bundle of media including the medium subjected to the liquid application or second processing that is the desired processing performed on the bundle of media without subjecting the medium to the liquid application.
