摘要： A solenoid device has a solenoid and a control portion. The solenoid has a body, a plunger, an attracting coil, a retaining coil, and a biasing member. The plunger is arranged selectively either in an attracted position, pulled into the body, or in a returning position, protruding out of the body. Fed with a voltage, the attracting coil generates an attracting force causing the plunger to move from returning position to attracted position. Fed with a voltage, the retaining coil generates a retaining force, weaker than the attracting force, causing the plunger to move to attracted position. The biasing member biases the plunger toward returning position. The control portion controls operation of the solenoid. When moving the plunger from returning position to attracted position, the control portion first starts applying the voltage to the retaining coil and then starts applying the voltage to the attracting coil.

摘要： A cleaning unit includes a pressing roller for pressing a web for removing ink adhering to a conveying surface of a resist roller that conveys a sheet on which the ink has been discharged, against the conveying surface. A cleaning liquid supply unit supplies a cleaning liquid to an unused portion of the web. A web drive mechanism supplies the unused portion of the web to the nip region between the pressing roller and the conveying surface. A controller supplies the unused portion to which the cleaning liquid has been supplied by the cleaning liquid supply unit to the nip region by using the web driving mechanism thereby removing the ink from the conveying surface, and subsequently supplies the unused portion to which the cleaning liquid has not been supplied to the nip region by the web driving mechanism thereby removing the cleaning liquid remaining on the conveying surface.

摘要： An image forming apparatus has a printing section, a cooling mechanism, a suction adjustment mechanism, and a controller. The printing section includes a fixing unit for heating a sheet having a toner image put on it, and discharges the sheet after fixing. The cooling mechanism includes a suction port, a blower motor for rotating a fan, and a blowing duct for blowing air onto the sheet. The suction adjustment mechanism moves a suction adjustor between an open position where the suction port is open and a shut position where the suction port is closed. The controller moves the suction adjustor the closer to the shut position the smaller the set thickness of the sheet.
