IMAGE FORMING APPARATUS, METHOD AND A NON-TRANSITORY, COMPUTER-READABLE STORAGE MEDIUM THEREFOR

摘要

An image forming apparatus includes a control device that detects a change in a first state concerning placement and removal of sheets in a sheet feed device or mounting and demounting of the sheet feed device and detects a second change in a second state concerning placement and removal or mounting and demounting of a member. When the control device detects the first change, the control device displays, on a display, first display information prompting for the user to enter settings concerning the type of sheets to be supplied to the sheet feed device. After accepting settings, the control device counts a predetermined time and deletes the first display information. When detecting the second change, the control device displays the display information for a longer time. Accordingly, when the user checks or sets the first display information about sheets, convenience is improved.

主权项

1. An image forming apparatus comprising:
a body; a sheet feed device; an image forming device configured to form an image on a sheet fed from the sheet feed device; a first sensor configured to output a first signal according to a first state concerning placement and removal of a sheet in the sheet feed device or output a first signal according to a first state concerning mounting and demounting of the sheet feed device; a second sensor configured to output a second signal according to a second state concerning placement and removal or mounting and demounting of a member, the member being placement and removal in another sheet feed device or being mounted in and demounted from the body; a display; and a control device configured to:
detect a first change in the first state based on the first signal output from the first sensor;detect a second change in the second state based on the second signal output from the second sensor;control the display to display first display information that prompts setting of a setting concerning a type of a sheet to be supplied to the sheet feed device on the display in response to the detection of the first change; count a time, the counting being started after the first display information has been displayed on the display; delete the first display information from the display after a prescribed time has been counted; and extend a display time displaying the first display information on the display, when the second change is detected while the first display information is displayed on the display, the display time is extended compared with a case in which, the second change is not detected while the first display information is displayed on the display.
