A printing apparatus, including a sheet conveyer unit with a first roller unit, a printer unit, and a controller, is provided. The controller executes a first-face printing process, wherein an image is printed on a first face of a sheet; a switchback process, wherein the sheet after the first-face printing process is conveyed in a reverse direction by the first roller unit; a second-face printing process, wherein the image is printed on a second face of the sheet; a first ink amount determining process to determine whether an ink amount discharged in the first-face printing process at an end area of the sheet is one of greater than and equal to a first threshold amount; and a switchback setting process, wherein, if the ink amount is smaller than the first threshold amount, a rotation speed of the first roller unit is set at a higher rotation speed.

A removable media handling module includes a body that is horizontally slidable into and removable from an imaging apparatus. The media handling module includes a lower media guide extending between a front and a rear of the body. With the media handling module inserted into the imaging apparatus, the lower media guide is positioned parallel to and spaced from a corresponding upper media guide mounted in the imaging apparatus to form at least a portion of a duplex media path therebetween. A drive mechanism including a clutched gear is operably connected to a feed roll assembly of the media handling module. The clutched gear is freely rotatable in a first direction that causes the feed roll assembly to rotate in a media process direction for feeding a printed media sheet along the duplex media path and is restrained from rotating in a second direction opposite the first direction.

The media handling module includes a lower media guide extending between a front and a rear of the body in a direction of insertion of the body into the imaging apparatus. With the media handling module inserted into the imaging apparatus, the lower media guide is positioned parallel to and spaced from a corresponding upper media guide mounted in the imaging apparatus to form at least a portion of a duplex media path therebetween. The media handling module includes a media feed through channel extending from a bottom of the body to an entrance of a simplex media path to allow media to be fed from a media tray below the media handling module and into the simplex media path when the media handling module is installed in the imaging apparatus.

The present sheet conveying apparatus includes: a resist roller pair that corrects skew of a sheet conveyed from a sheet supplying unit; and a guide portion disposed at an upstream side relative to the resist roller pair in a sheet conveying direction, the guide portion including a first guide and a second guide disposed opposite to the first guide with a sheet conveying path therebetween, the second guide being located at a projection side of a curved portion formed in the sheet when a tip of the sheet is conveyed to a nip portion of the resist roller pair that is stopped, the second guide being divided into a plurality of divided guides in an axial direction of the resist roller pair, a flexible film being disposed to cover at least a portion of a space between the plurality of divided guides.

A sheet conveyance apparatus including an openable member, a first conveyance roller, a second conveyance roller, a holding member, an urging member, and a reduction portion is provided. The first conveyance roller is provided in an apparatus body, and the second conveyance roller is provided in the openable member. The holding member rotatably holds the second conveyance roller, and the urging member urges the holding member in a pressing direction. The reduction portion includes a swingable member provided in the openable member and an abut portion provided in the apparatus body, and reduces a force applied to the openable member by the urging member when opening or closing the openable member.

A sheet conveying device includes a conveying unit configured to convey sheets along a predetermined conveyance path, and a cover member disposed at a position covering the conveying unit and constituting one of exterior surfaces of the sheet conveying device. The cover member includes a first base portion constituting one of the exterior surfaces, a second base portion facing the first base portion across a space, and a plurality of linking portions provided between the first base portion and the second base portion and linking to both the first base portion and the second base portion. The first base portion, the second base portion, and the plurality of linking portions are integrally formed of a resin material into one piece. The second base portion includes a plurality of ribs protruding from a surface of the second base portion opposite to the first base portion.

The second base portion includes a plurality of ribs protruding from a surface of the second base portion opposite to the first base portion.

An image recording device is provided, having a recording unit configured to record an image on a sheet, and a tray disposed below the recording unit. The tray includes a sheet holding surface configured to hold the sheet. Additionally, the image recording device includes a sheet feeder disposed between the recording unit and the tray. The sheet feeder includes a roller for feeding the sheet from the tray. The roller is configured to move between a first roller position in which the roller contacts the sheet holding surface of the tray and a second roller position in which the roller is separated from the sheet holding surface. A return guide, disposed between the recording unit and the sheet feeder, defines a second conveying path to guide the sheet having an image recorded on one side thereof back to the feed guide. The return guide has a first opening configured to accommodate the roller of the sheet feeder when the roller is in the second roller position.

A transport mechanism for a peripheral device and an operating method including the same are provided. The transport mechanism includes a tray, at least a transport roller, a detector, a trigger component and a processor. The tray includes an opening extending through the tray. The transport roller is rotatably installed in the opening and protruded from the tray to transport a flexible object to move along a transport path. The detector near the tray has a detecting area. The trigger component is located in the opening and spaced apart from the flexible object on the transport path. The flexible object deviated from the transport path presses the trigger component to enter or leave the detecting area and triggers the detector to transmit an abnormal detecting signal. The processor receives the abnormal detecting signal to stop the transport roller.
