摘要： An image forming apparatus includes a main body, an image forming unit, a sheet tray disposed below the image forming unit, and a retransport assembly configured to transport a sheet along a retransport path including first, second, and third retransport path portions in a transport direction. The retransport assembly includes a portion of the sheet tray defining the first retransport path portion, a connecting unit and a retransport unit, which are disposed below the sheet tray. The connecting unit defines the second retransport path portion connected to an upstream end of the third retransport path portion in the transport direction. The retransport unit is movable between a stored position and a pulled-out position. The retransport unit at the stored position defines the first retransport path portion connected to an upstream end of the second retransport path portion in the transport direction.

摘要： There is provided a sheet conveyance apparatus including: a loader unit loading sheets, a feeding unit feeding the sheets from the loader unit, a separating unit separating and conveying the sheets one by one, a detecting unit detecting the sheets, and a controller. The controller is configured to: measure a time from instructing the feeding unit for operation of feeding one of the sheets to the detecting unit detecting that sheet, and determine that there is a decrease in a capability of the feeding unit or the separating unit in a case that the measured time does not fit into a time needed to convey the sheet from a position of starting a normal operation of feeding the sheet to the position of the detecting unit.

摘要： A sheet conveying device includes: a sheet cassette including a first housing, a pressing plate, a raising plate, a first resilient member, and a second resilient member; a second housing; a sheet-cassette accommodating portion; a first electrode; a second electrode; a sheet conveyor; a driver; a first output device that outputs a first signal and a second signal; a second output device that outputs a rotation pulse signal; and a controller that receives the first signal, the second signal, and the rotation pulse signal. The controller counts pulses of the rotation pulse signal received from the second output device, determines the number of pulses of the rotation pulse signal, and determines an amount of upward movement of the pressing plate based on the number of pulses of the rotation pulse signal.

摘要： An image forming apparatus, having a housing, a flapper swingable relatively to the housing between a first position and a second position; a pressure link swingable relatively to the housing and the flapper, a first contact surface arranged on the housing, a first urging member to urge the flapper to swing relatively to the pressure link toward the first contact surface, a second urging member to urge the pressure link to act on the flapper to tend toward staying in the first position, and a flapper switcher having a pressure applier movable between a pressing position and a separated position, is provided. The flapper is swingable relatively to the pressure link against an urging force from the first urging member, after the pressure applier presses the pressure link to move the flapper from the first position to the second position and when the flapper contacts the first contact surface.

摘要： An image forming apparatus includes an image forming unit, a retransport assembly, and a controller. The retransport assembly includes a first transport roller pair, a second transport roller pair, and a skew roller pair configured to alone transport, in a skewed manner, a sheet spaced from the first transport roller pair and the second transport roller pair, and a reference wall. The controller controls the retransport assembly and executes a waiting operation to cause the sheet to wait at the retransport assembly. The controller is configured to execute the waiting operation by stopping the skew roller pair and one of the first transport roller pair and the second transport roller pair in a state in which the sheet is nipped by the skew roller pair and the one of the first transport roller pair and the second transport roller pair.
