Image forming apparatus
An image forming apparatus includes a development device, and a control unit that controls the development device. The development device includes a toner collection mechanism having a duct, a filter, and an exhaust fan. The duct is connected to a conveyance chamber of the development container and allows air in the conveyance chamber to flow through. The filter is disposed at a connecting part between the duct and the conveyance chamber, and collects toner flowing into the duct from the conveyance chamber. The exhaust fan makes the air in the conveyance chamber flow to the outside via the duct. The control unit changes rotational frequency or operation frequency of the exhaust fan based on current detected by a current detection unit at non-image forming time.
POWER SUPPLY APPARATUS AND IMAGE FORMING APPARATUS
The power supply apparatus includes a switching element connected to a primary winding of a transformer to which an input voltage is applied; a feedback unit configured to output a first feedback voltage according to an output voltage, the output voltage induced in a secondary winding of the transformer and output to a load; a current detection unit for detecting a current flowing to the switching element and output a second feedback voltage according to the current detected; a limiting unit for limiting the first feedback voltage so that the current flowing to the switching element is below a predetermined current value; an output unit for outputting a driving signal for the switching element based on the first feedback voltage limited by the limiting unit and on the second feedback voltage; and a control unit for controlling the switching element according to the driving signal output from the output unit.
Image forming apparatus
An image forming apparatus includes an image forming unit, an execution unit that executes dew condensation elimination operation for eliminating dew condensation in the image forming unit, a setting unit that sets a dew condensation prevention mode for executing the dew condensation elimination operation to an enabled state, a display unit, and a control unit that causes the display unit to display a warning screen and selects a type of image forming job to be restricted during execution of the dew condensation elimination operation in a case where the dew condensation prevention mode is set to an enabled state, wherein, in a case where an image forming job is received during execution of the dew condensation elimination operation, the control unit determines whether the received image forming job is executable based on the type of job selected.
Information processing apparatus, method for controlling information processing apparatus, and storage medium
An information processing apparatus configured to communicate with a connectable and removable nonvolatile storage device includes a display device, and a display control unit configured to control display processing that a storage device not specified as a backup destination for backing up data in the information processing apparatus is displayed on the display device as a removal instruction target, and a storage device specified as a backup destination is not displayed on the display device as a removal instruction target, wherein the display control unit is implemented by at least one processor.
IMAGE FORMING APPARATUS
An image forming apparatus includes an image forming unit, an execution unit that executes dew condensation elimination operation for eliminating dew condensation in the image forming unit, a setting unit that sets a dew condensation prevention mode for executing the dew condensation elimination operation to an enabled state, a display unit, and a control unit that causes the display unit to display a warning screen and selects a type of image forming job to be restricted during execution of the dew condensation elimination operation in a case where the dew condensation prevention mode is set to an enabled state, wherein, in a case where an image forming job is received during execution of the dew condensation elimination operation, the control unit determines whether the received image forming job is executable based on the type of job selected.
SHEET CHARACTERISTIC DETECTION APPARATUS, IMAGE FORMING SYSTEM, AND RECORDING MEDIUM
A sheet characteristic detection apparatus includes a first characteristic detector that is arranged on a conveyance path of a sheet and detects first characteristic information corresponding to a first characteristic of the sheet, and a second characteristic detector that is arranged on the conveyance path and detects second characteristic information corresponding to a second characteristic of the sheet, in which, on the basis of a detection result of any one of the first characteristic detector and the second characteristic detector, the other characteristic detector is controlled.
Image forming device configured to cut sheet- type medium and form image on cut medium
An image forming device comprises a media container accommodating a sheet-type medium, an image forming engine, a media conveyor configured to convey the sheet-type medium along a conveyance path from the media container to the image forming engine. The media conveyor has a plurality of conveying rollers including a first conveying roller arranged on an upstream side of the image forming engine and a second conveying roller arranged on a downstream side of the image forming engine. The image forming device further comprises a cutter arranged on an upstream side along the conveyance path with respect to the second conveying roller, and a controller. The controller is configured to control the media conveyor in such a manner that the cut sheet-type medium is conveyed and discharged toward outside after a power is on and before first execution of the image forming process.
