  • Publication number: 20250033919
    Abstract: A media processing apparatus includes a slit insertable a sheet bundle of multiple sheets, a sheet-bundle holder, a liquid applier, a press binder, and a controller. The sheet-bundle holder holds the sheet bundle and detects the thickness of the sheet bundle. The liquid applier applies liquid to the sheet bundle. The press binder presses and binds the sheet bundle to perform press-binding process. The controller causes the sheet-bundle holder to hold the sheet bundle and detect the thickness of the sheet bundle, determines whether to cause the liquid applier to apply liquid to the sheet bundle based on the thickness of the sheet bundle, causes the liquid applier to apply the liquid to the sheet bundle when it is determined that the thickness of the sheet bundle is equal or larger than a prescribed thickness, and causes the press binder to press and bind the sheet bundle.
