An example a media sensor device may comprise a light source positioned on a first side of a media pathway, a light path to receive a light from the light source and direct the light through a plurality of openings from the first side of the media pathway to a second side of the media pathway, and a light sensor on the second side of the media pathway to detect print media within the light path based on an intensity of light received from the light source, wherein a heated enclosure aligns the light sensor with the light path.

A turnable sheet stopper blocks and passes a sheet conveyed on a sheet guide, and includes a proximal portion, a distal portion connected to the end of the proximal portion, and a folding mechanism that connects the distal portion to the proximal portion. The sheet stopper transitions between first and second positions. In the second position, the proximal and distal portions integrally turn to the downstream side in the sheet conveyance direction to allow the sheet to pass. The sheet stopper transitions from the second position to a third position when a user draws out the sheet from an upstream side. In the third position, the distal portion folds toward the upstream side to allow the sheet to be drawn out. During transition from the second position to the third position, the edge of the distal portion is located on or away from an outer surface of the sheet guide.

A conveyance apparatus includes a bearing rotator, an entrance rotator, an exit rotator, a first driver circuit, a downstream conveyor, a second driver circuit, and a recording medium detector. The entrance rotator receives a recording medium at a first position. The downstream conveyor receives the medium at a second position. As a process of removing the medium, the first driver circuit starts rotation operation after the second driver circuit starts driving the downstream conveyor and rotates the rotators for not less than a period of time for the medium to be conveyed from the first position to the second position. The second driver circuit continues driving the downstream conveyor for not less than a period of time for the medium to be conveyed from the second position to a position at which the medium is detected after the rotation operation of the first driver circuit is stopped.

A sheet accommodating apparatus includes an apparatus body, a first cassette to be drawn out in a draw-out direction with respect to the apparatus body, a second cassette disposed adjacent to the first cassette in a vertical direction, a holder member attached to the apparatus body, and a first light emitting member and a second light emitting member that are supported by the holder member. The first cassette includes a first accommodating container and a first cover. The second cassette includes a second accommodating container and a second cover. The first cover has a first hole in a position opposing the first light emitting member such that the light emitted from the first light emitting member passes therethrough. The second cover has a second hole provided in a position opposing the second light emitting member such that the light emitted from the second light emitting member passes therethrough.

A processing system includes a processing apparatus, a feeding apparatus, an ejection apparatus, and circuitry. The processing apparatus includes a processing device to execute a process on each of objects including a first object and a second object. The feeding apparatus feeds the objects to the processing apparatus. The ejection apparatus ejects the objects sent from the processing apparatus. The ejection apparatus includes an ejection purge portion to receive the second object traveling in the ejection apparatus. The circuitry sets whether to permit ejection of the second object not jammed to the ejection purge portion in case of a jam of the first object in the processing system. The circuitry causes the second object to be ejected to the set ejection purge portion, in response to detection of the jam of the first object.

A fixing device includes first and second rotatable members, a moving mechanism, a flag, a sensor, a movable guide, and a stationary guide. The moving mechanism is configured to move the first rotatable member away from the second rotatable member. The flag is provided downstream of the nip with respect to a recording material feeding direction and retractable by passing of the recording material. The sensor is configured to detect whether or not the flag is retracted by contact with the recording material. The movable guide is movable together with the first rotatable member away from the second rotatable member and from the flag by the moving mechanism. The stationary guide is fixed at a position opposing the flag, irrespective of a position of the movable guide member. The stationary guide does not move together with the movable guide.

A printing system includes a product inspection unit configured to perform product inspection on a print product based on a scanned image generated by reading the print product with an image printed thereon and correct answer images stored in advance, a post-processing unit configured to perform post-processing on the print product, and a control unit configured to, upon occurrence of a jam in the print product, control the printing unit to perform reprinting, wherein, upon occurrence of a jam while the post-processing is performed, the product inspection unit is notified of identification information regarding the print product on which printing is started by the reprinting, and wherein, based on the identification information, the product inspection unit references any of the correct answer images corresponding to a scanned image generated by the reprinting and performs the product inspection on the print product.

An image forming apparatus includes a sheet storage unit including a sheet tray on which one or more sheets are to be stacked, a sensor configured to detect that the sheet storage unit is being operated, and a processor configured to execute a predetermined process after the sensor detects that the sheet storage unit has been operated, and a predetermined condition relating to an occurrence of the sheet conveyance error is satisfied.

A finisher apparatus includes an actuator to control a component of the finisher apparatus to perform a finishing operation on a print medium. A sensor is provided to sense the print medium in a print-medium path in the finisher apparatus. A processor is coupled to the actuator and the sensor. The processor is to execute instructions. The instructions are to actuate the actuator to eject the print medium from the print-medium path in response to a signal from the sensor indicative of a jam of the print medium in the finisher apparatus.

An image forming apparatus includes a cartridge including an abutting portion and an apparatus main body. The apparatus main body includes a mounting portion of the cartridge, a fixing portion for fixing the toner image, an attachable/detecting mechanism of the cartridge, a shutter, and a moving member. The attachable/detecting mechanism includes an acting member movable between a first position and a second position by the mounting of the cartridge. The shutter is movable between a closed position and an open position, and a moving member moves both the shutter and the acting member and includes an abutted portion. When the cartridge is moved, the moving member is moved by abutment of the abutting portion of the cartridge with the abutted portion, the acting member moves from the first position to the second position, and the shutter moves from the closed position to the open position.
