Abstract: A sheet feeding apparatus includes: a placer that allows a plurality of sheets to be placed on the placer; an air feeder including a front-end fan that generates an airflow from a front-edge side in a sheet feeding direction of a bundle of sheets placed on the placer toward the bundle of sheets; an attracting conveyor that attracts an uppermost sheet separated by the air feeder from the bundle of sheets placed on the placer and conveys the uppermost sheet; a detector that detects, in the conveyance of the uppermost sheet by the attracting conveyor, an amount of co-feeding of a next sheet together with the uppermost sheet; and a hardware processor that executes air-volume control to the front-end fan such that an air volume of the front-end fan increases with an increase in the amount of co-feeding detected by the detector.

Abstract: Provided are an image forming apparatus, a method of controlling sheet insertion and a non-transitory computer-readable recording medium. The image forming apparatus includes a print engine, an image checker, a sheet inserter, a sheet ejector and one or more controllers. When the image checker receives a media sheet output from the print engine, the one or more controllers perform a check whether an image formed on the media sheet is defective or not, by using measured image obtained by a sensor of the image checker. The one or more controllers further cause a sheet inserter to start putting an insertion sheet into the sheet path, after a determination that an image of one of media sheets output from the print engine is non-defective is made, as a result of the check.
