IMAGE FORMING APPARATUS
An image forming apparatus, having a photosensitive drum, an intermediate transfer belt located at a lower position with respect to the photosensitive drum to contact the photosensitive drum, a secondary transfer roller contacting the intermediate transfer belt, a first sheet tray located at a lower position with respect to the intermediate transfer belt to store a sheet, and a sheet guide to guide the sheet stored in the first sheet tray to a position between the intermediate transfer belt and the secondary transfer roller, is provided. The sheet guide is located between the intermediate transfer belt and the first sheet tray with regard to a vertical direction and has a curved section. A contact area between the secondary transfer roller and the intermediate transfer belt is located at a lower position with respect to an upper end portion of the curved section.
IMAGE FORMING APPARATUS
An image forming apparatus includes an image forming unit, a discharge unit, a double-sided conveyance path, a sheet plate, a skew correction unit, and a frame. The discharge unit discharges a sheet having an image from the image forming unit. The double-sided conveyance path conveys the sheet again to the image forming unit. The sheet plate restricts a position of an end, in a sheet width direction, of the sheet.
Adjusting positions of images
According to some examples, a method comprises successively transferring a series of images from an imaging surface to an intermediate transfer member, ITM, then from the ITM to positions on a web substrate. The method may comprise intermittently adjusting a position at which particular images are transferred to the ITM by a first defined distance laterally across the ITM and by a second defined distance longitudinally with respect to the ITM. The method may comprise adjusting a position at which the particular images are transferred to the web substrate by approximately the first defined distance laterally relative to the ITM and by approximately the second defined distance longitudinally relative to the ITM. The method may comprise, after a first defined number of intermittent position adjustments, changing a direction in which the position is adjusted. A print apparatus and a machine-readable medium are also disclosed.
Printing apparatus with jam release mechanism
A printing apparatus includes: a conveyor including a first pair of conveyance rollers and a second pair of conveyance rollers each configured to nip and convey a sheet; a first jam releaser configured to separate rollers of the first pair of conveyance rollers from each other; a second jam releaser configured to separate rollers of the second pair of conveyance rollers from each other; and a controller configured to control the conveyor. In stopping sheet conveyance by the conveyor upon occurrence of a failure, the controller controls the conveyor to prevent a sheet from being nipped only by the first pair of conveyance rollers prior to separation of the rollers of the first pair of conveyance rollers from each other by the first jam releaser.
Feed path switching member for an image forming apparatus to guide a recording medium to a first or second feed path connecting a fixing unit and a feed roller of an inkjet image forming unit
An image forming apparatus employing an electrophotographic image forming unit and an inkjet image forming unit, thereby being capable of printing an image on each of a front surface and the back surface of a recording medium.
Feed path switching member for an image forming apparatus to guide a recording medium to a first or second feed path connecting a fixing unit and a feed roller of an inkjet image forming unit
An image forming apparatus employing an electrophotographic image forming unit and an inkjet image forming unit, thereby being capable of printing an image on each of a front surface and the back surface of a recording medium.
Image forming apparatus, method, and computer-readable medium for setting image forming conditions in duplex printing
An image forming apparatus includes a second conveyance guide diverging from a first conveyance guide at a bifurcation and joining the first conveyance guide at a junction, the bifurcation being downstream of a first position of an image former in a conveyance direction, the junction being upstream of the first position in the conveyance direction, first and second sensors disposed in second and third positions between the junction and the first position along the first conveyance guide, respectively, and a controller that, when a sheet passes through the second and third positions for a second time, detects a surface characteristic of a side of the sheet by the first sensor and determines an image forming condition for the side based on the surface characteristic of the side and a basis weight detected by the second sensor when the sheet passed through the second and third positions for a first time.
Image forming apparatus
An image forming apparatus includes an image forming unit and a re-conveyor. The re-conveyor includes a first bevel gear, a second bevel gear, a first re-conveying roller, a shaft member, a first engaged member, a second engaged member, and an engaging member. When the second bevel gear is rotated in a rotational direction by a driving force transmitted from the first bevel gear, the engaging member is moved to a second position and engaged with the first and second engaged members to rotate the shaft member in a rotational direction. When the shaft member is rotated in the rotational direction by a driving force transmitted from the first re-conveying roller, the engaging member is moved to a first position, disengaged from the second engaged member, and engaged with the first engaged member to interrupt transmission of the driving force from the shaft member to the second bevel gear.
Printing apparatus and printed matter printed by same
A printing apparatus includes a printer and a sheet feeder. The sheet feeder feeds a sheet to the printer in a feed direction. The printer prints a folding guide line on the sheet with a transparent recording agent or a recording agent having a similar color close to the color of the sheet.
Image forming system including a plurality of recording medium cooling apparatuses and an uncurling apparatus
In a feeding direction of a recording material, a recording material cooling device is provided downstream of a fixing device, a curl reducing device is provided downstream of the recording material cooling device, and another recording material cooling device is provided downstream of the curl reducing device. By this configuration, occurrence of image defect by the recording material cooling device during the feeding of the recording material can be suppressed, and the curling of the recording material can be reduced after the recording material is cooled.
