Image forming apparatus

摘要

An image forming apparatus includes a stacking portion on which a sheet is to be stacked, an image forming unit, a size detection unit, a setting unit, a notification unit, and a control unit. The image forming unit forms an image on a sheet fed from the stacking portion. The size detection unit detects a size of a sheet stacked on the stacking portion. The setting unit sets at least one sheet size to be allowed for use at the image forming apparatus. The notification unit provides notification of information. The control unit causes the notification unit to provide a warning in a case where the size of the sheet detected by the size detection unit is not included in the at least one sheet size set by the setting unit.

1. An image forming apparatus comprising:
a stacking portion on which a sheet is to be stacked; an image forming unit configured to form an image on a sheet fed from the stacking portion; a size detection unit configured to detect a size of a sheet stacked on the stacking portion; a determining unit configured to determine, regardless of a designated sheet size used in an image formation job, an effective size group usable for image forming from among a plurality of size groups, each of which has a different size series of a sheet; a notification unit configured to provide notification of information; and a control unit configured to adopt the sheet size detected by the size detection unit as a size for a sheet in a case where the detected size is included in the effective size group determined by the determining unit, and cause the notification unit to provide a warning in a case where the size of the sheet detected by the size detection unit is not included in the effective size group determined by the determining unit.
