Method for conditioning paper, which comprises a first step of cooling and one of applying a liquid to the paper. In the cooling step, the temperature of the paper is reduced, e.g. below ambient temperature or below the dew point of a liquid-saturated gas mass applied in the liquid-application step. The gas may be ambient air and the liquid water. Control means monitor the amount of liquid applied to the paper by means of measuring the relative humidity of the air, the absolute humidity of the paper, the temperature of the device where the liquid is applied and the temperature of the paper. The invention also comprises a device for applying the method and it may be applied to paper emerging from a printer, e.g. a digital printer.

An image forming apparatus includes: a feed tray that contains printing paper therein; a user authentication unit that authenticates a user who is permitted to print; a paper loading detection unit that detects printing paper loaded into the feed tray; a memory device that stores a user authenticated as a paper-supplementing user; a paper feeding mechanism that feeds the printing paper from the feed tray; a paper jam detection unit that detects a paper jam; and a controller that controls a print job. The controller, when a paper jam has occurred, determines whether or not the paper jam is due to the paper-supplementing user having loaded the printing paper in an improper manner. Upon determining that the paper jam is due to the paper-supplementing user having loaded the printing paper in an improper manner, the controller, subsequently when the paper-supplementing user uses, requests that a loading condition be checked.

The invention discloses an automatic paper feeding mechanism for a copying machine and relates to the technical field of copying machines.
