  • Patent number: 10509352
    Abstract: When an image forming apparatus such as an MFP runs out of supplies, such as paper or toner, the user will need to load paper in the paper tray or replace the toner cartridge. However, the user occasionally has difficulty in opening the paper tray or the front cover because his/her hands are carrying the additional supplies. For example, the user may have to put the belonging down to open up the paper tray or the front cover. The image forming apparatus reacts to the user's desire in a mechanical manner by opening the paper tray or the front cover.

  • Publication number: 20190291994
    Abstract: A sheet conveying device, which is included in an image forming apparatus and a post processing device, includes multiple position detectors and a position corrector. The multiple position detectors are aligned along a sheet conveying direction and configured to detect a side end of a sheet. The position corrector is configured to convey the sheet and correct a position of the sheet based on a positional deviation amount of the sheet, obtained by a detection result of the multiple position detectors. The positional deviation amount of the sheet is obtained by an extreme downstream position detector in the sheet conveying direction, of the multiple position detectors.
