Abstract:
A sheet conveying apparatus which detects an end part position of a sheet in a sheet width direction orthogonal to a conveying direction of the sheet conveyed on a sheet conveying path, comprising a plurality of sensor portions; a holding portion which holds the plurality of sensor portions; a plurality of aperture stops which is disposed between the light emitting portion and the light receiving portions and which is provided on the holding portion; and a driving portion which causes a movement of the holding portion in the sheet width direction.
Abstract:
A transported material transporting device including: a power transmission switching mechanism configured to switch the transmission of the power between the intermediate gear and the cam drive gear between a transmitted state and a blocked state; a detection lever provided in the reversing path and configured to detect the presence or absence of the material to be transported which enters the reversing path; and a blocked-state locking mechanism configured to lock the blocked state of the power transmission switching mechanism when the discharging roller is in the released state, wherein the locked state of the blocked-state locking mechanism is released and the power transmission switching mechanism is switched from the blocked state to the transmitted state upon detection of the position of the trailing end of the material to be transported entering the reversing path by the detection lever.
Abstract:
An image forming apparatus includes a first and second ejection portions, a first and second conveying paths, a branch portion connecting the first conveying path with the second conveying path, a switching member movable between a first and second positions, a drive unit that moves the switching member from the first position to the second position or vice versa, a reference position setting unit setting the reference position of the switching member in an initial state, and a control unit controlling the drive unit such that the switching member in the initial state is positioned at the reference position set by the unit.
Abstract:
To effectively output a job in which a double-sided page and a single-sided page are mixed by using a double-sided conveying path and a single-sided conveying path or the single-sided conveying path, a method for controlling a printing apparatus comprises: specifying a print prediction time in a case where the job is executed by using a first printing process of printing the double-sided page and the single-sided page in the job by using the double-sided conveying path, and a print prediction time in a case where the job is executed by using a second printing process of printing the double-sided page and the single-sided page in the job by switching between the double-sided conveying path and the single-sided conveying path; and executing the job by using, from either the first printing process or the second printing process, the printing process for which the specified print prediction time is shorter.
Abstract:
An erasing device includes a line scanner on an upstream side in a recording medium conveying direction, includes a thermal head downstream in the recording medium conveying direction of the line scanner, and includes a platen in a position opposed to the thermal head as a heating device across a recording medium conveying path. The erasing device causes the heat generating elements of the thermal head in positions corresponding to color and density sensors in positions of an image detected by the line scanner to generate heat. The erasing device controls, according to detected colors or density, a quantity of heat to be generated.
Abstract:
An image forming apparatus includes an apparatus body, a conveyance unit withdrawably mounted on the apparatus body, and a driving mechanism disposed in the apparatus body. The conveyance unit has a power transmission member which transmits the driving force generated by the driving mechanism to the conveyance member. The power transmission member has a drive input section disposed on the outside of a housing for receiving the driving force. The driving mechanism is disposed on the apparatus body side, and has a drive output section engageable with the drive input section. The drive input section and the drive output section engage with each other in a mounted state that the conveyance unit is mounted on the apparatus body, and the engagement between the drive input section and the drive output section is released in a withdrawn state that the conveyance unit is withdrawn from the apparatus body.
Abstract:
In an image forming apparatus, when a first sheet discharger discharges a sheet bearing an image in a first direction from a proximal end to a distal end of the image forming apparatus, a post-processing device performs post-processing including at least one of stapling, punching, stamping, and sorting of the sheet discharged from the first sheet discharger. After a second sheet discharger discharges the processed sheet in a second direction opposite to the first direction in which the first sheet discharger discharges the sheet bearing the image, a sheet stacker stacks the sheet discharged from the second sheet discharger. A sheet conveyance path is provided between the first sheet discharger and the second sheet discharger. An opening is provided between the sheet stacker and an image reader so that the sheet discharged from the second sheet discharger can be retrieved from the sheet stacker in the second direction.
Abstract:
A reverse conveying apparatus which again conveys a sheet formed an image by an image forming portion to the image forming portion includes a plurality of roller grippers which supports a sheet formed an image, and a belt which moves the roller grippers to a receiving position where a sheet is received and a carry-out position where a supported sheet is conveyed out. When a sheet is conveyed out in the carry-out position, the sheet is conveyed out such that a rear end thereof when it is received at the receiving position is a leading end.
Abstract:
An image forming apparatus includes a sheet feed unit which feeds a sheet to an image forming unit forming an image on the sheet; a re-transport roller which reverses the sheet with a toner image fixed on the sheet and re-transports the sheet to the image forming unit; and a control unit which controls a sheet feed operation of the sheet feed unit for feeding the sheet, wherein, as the temperature of the re-transport roller sensed by the temperature sensing unit is lower, the control unit retards a timing to cause the sheet feed unit to start the sheet feed operation when a duplex image formation in which the image is formed on both sides of the sheet is performed after a one-side image formation is completed.
Abstract:
An image forming apparatus includes: a sheet feed unit that feeds a sheet to an image forming unit forming a toner image on the sheet; a fixing unit that fixes the toner image formed in the image forming unit to the sheet; and a control unit that controls the sheet feed unit, when starting duplex image formation for forming both sides of the sheet after an one-side image formation, the control unit retards a timing to cause the sheet feed unit to start the sheet feed operation as the number of sheet with an image formed on one side thereof in the one-side image formation is greater.
