ABSTRACT:
A printer having a fan folded output is provided with an output catching tray which cantilevers upwardly at an angle of 35.degree.-55.degree. from the printer output. The tray includes side walls defining a bottom which bears on the top of the printer. The sidewalls each define integrally formed hooks for catching onto the printer at any bar of fastening disposed in the area of the output. These books enable the cantilevered support to occur. At the bottom of the tray, an arcuate and cam-like surface is disposed against the printer output. This cam-like surface takes horizontal output from the printer and causes it to pass upwardly over its surface. The cam surface extends from an angle in the range of 45.degree. in vicinity of the printer to a slope beyond horizontal at the bottom of the paper catching tray. The end of the cam and the bottom of the paper catching tray form a notch. The paper catching tray extends upward from the notch at an angle between 30 to 60 degrees, the full length of the fan fold paper, and is preferably provided at the upper end thereof with a paper stop. In operation, fan folded paper output from the printer is fed to the tray, typically to the notch at the end of the cam surface and the beginning of the upwardly extending tray. Thereafter, when printer output occurs, the columnar strength of the paper combined with the natural weight of the paper as it lies on the tray surface causes a fan fold layering of the paper catching tray.
