Abstract: In a duplex printer with automatic duplex printing by recirculating the sheets printed on their first sides through a duplex path for printing their second sides before feeding them to the output path, electronic information corresponding to a pre-set maximum level of acceptable sheet weight for that printer is compared to a remote user job input with electronic information corresponding to the desired sheets to be printed. If exceeded, the printer automatically switches to a different duplex printing mode in which the heavyweight sheets are printed on only one side and fed to the output path, and a GUI at the printer automatically displays instructions to unload these simplex printed sheets and properly reload them in an input in the correct orientation to print their opposite sides with locally stored page images for those opposite sides, and printing is restarted at the printer rather than the remote job input site.

At least one image is formed on a sheet. A double-sided sheet conveying path is provided, which the sheet passes when being conveyed back to the image forming unit again to form an image on an opposite side surface of the sheet after an image is formed on one side surface of the sheet. A retaining member is provided on the double-sided sheet conveying path to retain the sheet on the double-sided sheet conveying path. A post-processing device carries out post-processing on sheets on which images have been formed by the image forming unit. A CPU circuit section, which controls conveyance of the sheet, provides control to convey the sheet on which the at least one image has been formed by the image forming unit to the double-sided sheet conveying path, cause the retaining member to temporarily retain the sheet on the double-sided sheet conveying path, and then convey the sheet to the post-processing device.

Abstract: An image generating apparatus equipped with detachable sheet conveyance units can reduce a first print time period at the time of releasing a sleep mode. An engine controller turns on an ON/OFF signal in response to a sleep release instruction. It sends via serial communication an OUT signal instructing to start an option paper feed cassette controller which is assigned higher priority, thereby starting the option paper feed cassette controller. It is possible to perform image generating operation in a state in which only an option paper feed cassette is started. In parallel with the image generating operation, a duplexer unit controller is started.

Abstract: A first reversing inlet path and a second reversing inlet path are branched from a path for transporting a sheet having an image formed thereon by a printer unit. A first reversing path and a second reversing path are connected respectively to the first reversing inlet path and the second reversing inlet path. The sheet having the image formed thereon by the printer unit is transported through the first reversing inlet path or the second reversing inlet path for reversing the sheet. When one of the first reversing inlet path and the second reversing inlet path is unusable, the sheet reversing operation is continued using the other reversing inlet path.
