发明名称 Sheet feeding apparatus and image forming apparatus
摘要 A packing material for distribution is formed in such a shape that, when the packing material attached in a deck unit fails to be removed, a control unit determines that no sheet is present on a tray based on detection signals from a sheet surface detection sensor and a sheet presence detection sensor. When a user checks the deck unit when the absence of sheets is displayed, the user can notice a failure to remove the packing material, thus preventing damage to a sheet feeding apparatus caused by the failure to remove the packing material for distribution.
