IMAGE PROCESSING APPARATUS
According to one embodiment, an image processing apparatus includes an apparatus main body, a first rotating body, a second rotating body, and a connection member. The first rotating body is configured to be openable and closeable and provided in the apparatus main body. The second rotating body is provided in the first rotating body. The second rotating body is configured to be openable and closable from the first rotating body in the same direction as that of the first rotating body. The connection member is linear. The connection member is configured to connect the apparatus main body and the second rotating body to each other and to restrict a rotation angle of the second rotating body.
SHEET CONVEYING DEVICE, FIXING DEVICE, AND IMAGE FORMING APPARATUS
A sheet conveying device includes a pair of conveyors each including a conveyance face to convey a recording medium inside an image forming apparatus. One of the pair of conveyors further includes an exposed face, a handle, and a swing fulcrum. The exposed face is exposed to an outside of the apparatus while an inside of the apparatus is open. The handle is exposed to the outside of the apparatus and operatable to expose the conveyance face to the outside of the apparatus while the inside of the apparatus is open. The swing fulcrum swings the one of the pair of conveyors to expose the conveyance face to the outside of the apparatus when the handle is operated while the inside of the apparatus is open. The handle includes a partial annular portion. The partial annular portion is included in a plane including a swing direction around the swing fulcrum.
Image forming apparatus
An image forming apparatus includes a detection member configured to detect a conveyance state of a recording medium, a control unit configured to sequentially execute a first operation for continuously executing a rotation operation of an image bearing member and an intermediate transfer member without stopping them when the detection member detects a failure, and a second operation for stopping the rotation operation of the image bearing member when the surface of the image bearing member is moved by a predetermined distance through the rotation operation of the image bearing member after the failure is detected.
Sheet feeding apparatus and image forming apparatus
Occurrence of a half-latch state when pushing a sheet stacking unit into a sheet feeding apparatus at an angle can be prevented. More specifically, inside a sheet feeding apparatus that accommodates and fixes the sheet stacking unit, a latch assembly in which left and right latches and a connecting portion that connects the two latches are configured and that operates integrally is provided. By this, even when one roller of the sheet stacking unit contacts one latch which rides up on the roller in a case where the sheet stacking unit is pushed into the sheet feeding apparatus at an angle, it is possible to hold off on engagement of the latches until the other roller passes the other latch.
LOCK MECHANISM OF DRAWER UNIT PROVIDED IN IMAGE FORMING APPARATUS
When a sheet jam is detected, a processor may perform the following process. In a case where a sheet is spanning a first conveyance path and a drawer unit, the processor maintains a lock unit in a locked state by supplying power to the lock unit via the drawer unit from a power supply without depending on whether a door is in an open state or a closed state. In a case where a sheet is not spanning the first conveyance path and the drawer unit, the processor controls supplying and disconnecting of power to the drawer unit from the power supply in accordance with whether the door is in a closed state or an open state.
PHOTORECEPTOR STRIPPER FINGERS WITH AN IMPROVED PROFILE FOR ULTRA-LIGHT WEIGHT MEDIA
An apparatus for stripping light weight and ultra-light weight media from a photoreceptor that is tacked thereto by electrostatic or vacuum force includes a set of low-tip stripper fingers configured to strip the light weight and ultra-light weight media from the photoreceptor. The low-tip stripper fingers are adjustable both in the cross process and in attack angle with respect to the photoreceptor in order to change the height at which the tip of each stripper finger is in relation to the photoreceptor and thereby prevent jams due to miss-strips. Additionally, dual stripper fingers are disclosed that support inboard and outboard edges of larger media in order to reduce dog ears and jams.
Sheet processing apparatus and control method
A sheet processing apparatus is described. The sheet processing apparatus includes a housing section, a conveyance mechanism and a controller. The housing section accommodates a sheet. The conveyance mechanism conveys the sheet accommodated in the housing section to a predetermined position at the downstream side in a sheet conveyance direction. The controller controls the conveyance mechanism to remove a needle-free binding section of a sheet bundle if a conveyance jam of the sheet occurs.
COOLING DEVICE, IMAGE FORMING APPARATUS AND IMAGE FORMING SYSTEM
With stoppage of recording material feeding including a first belt and a second belt (YES in S1), a controller causes cooling operation for the recording material by a cooling fan and a belt fan to continue without stop (S4). By continuing the cooling operation of a recording material cooling device, even if the recording material stagnates in the recording material cooling device in a state of being nipped by the first belt and the second belt, the temperature of the recording material can be lowered. Then, the toner on the recording material is cooled, the toner on the recording material is unlikely to adhere to the first belt or to the second belt.
IMAGE FORMING APPARATUS
An image forming apparatus includes a detection member configured to detect a conveyance state of a recording medium, a control unit configured to sequentially execute a first operation for continuously executing a rotation operation of an image bearing member and an intermediate transfer member without stopping them when the detection member detects a failure, and a second operation for stopping the rotation operation of the image bearing member when the surface of the image bearing member is moved by a predetermined distance through the rotation operation of the image bearing member after the failure is detected.
Image forming apparatus provided with a sheet processing device
To allow easy access to a jammed sheet when a sheet jam occurs in a sheet processing device installed inside the body of an image forming apparatus. An image forming apparatus is provided with a sheet binding unit that applies binding to sheets. The sheet binding unit has a carry-in port for receiving a sheet to be conveyed to a sheet carry-in path formed thereinside and an openable cover for opening the carry-in port. The end portion of the openable cover on the carry-in port side and an end portion of an operation part for inputting an operational item for the operation carried out in the image forming apparatus are arranged spaced apart from each other at a predetermined distance.
