A sheet processing apparatus laminates a partially joined two-ply sheet and a sheet medium inserted in the two-ply sheet. The sheet processing apparatus includes a heat presser, an information acquisition device, and control circuitry. The heat presser heats and presses the two-ply sheet and the sheet medium. The information acquisition device acquires information on the two-ply sheet and the sheet medium. The control circuitry sets a fixing temperature of the heat presser in accordance with the information of the two-ply sheet and the sheet medium acquired by the information acquisition device.

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.

A conveyance device includes a first temperature detector and a second temperature detector that detect a temperature of a heater. A recording medium detector detects a recording medium. The first temperature detector is separated from a center position of an elastic layer of a pressure rotator farther than the second temperature detector is in an orthogonal direction perpendicular to a recording medium conveyance direction. The first temperature detector is separated from the center position for a first length and disposed in a first span defined by the center position in the orthogonal direction. The recording medium detector is disposed in a second span opposite to the first span, separated from the center position for a second length smaller than the first length, and disposed in a minimum recording medium conveyance span where the recording medium having a minimum width in the orthogonal direction is conveyed.

An image forming apparatus comprises a plurality of sheet detection units, provided at different positions along a sheet width direction, configured to detect the sheet conveyed on a conveyance path. A controller determines, by using the plurality of sheet detection units, a presence or absence of a sheet being conveyed in each of a plurality of regions sectioned in the sheet width direction, and determines, based on input image data, a presence or absence of an image to be formed in each of the plurality of regions. The controller further determines, based on the above determination results, whether or not the image to be formed on the sheet being conveyed is to be formed with a deviation from the sheet, and controls an image forming operation in accordance with this determination result.

A monitoring system for pneumatic shafts and pneumatic shaft adapters. A sensor assembly is physically joined in operative engagement with the bladders of pneumatic shafts and adapters. Sensed data is wirelessly transmitted to a remote receiver for processing and display.

In a present vacuum treatment apparatus, a controller controls an auxiliary roller, a thermometer, a power source, and a temperature control mechanism, in which the controller detects a temperature of a base material wound and conveyed by a main roller, starts film deposition to form a film deposition material on the base material when the temperature of the base material is in a film deposition temperature range, adjusts, when the temperature of the base material is out of a threshold range after starting film deposition on the base material, the temperature of the main roller so that the temperature of the base material falls within the threshold range and adjusts an adhesion force between the main roller and the base material, and continues the film deposition of the film deposition material on the base material with the temperature of the base material in the film deposition temperature range.

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.
