This article describes 'Humidity Prevention Sheet' which makes easy to feed the print paper on the paper cassette equipped in the ACM (Automated Consulting Machine) or similar products which are installed in a public buildings where air conditioning is usually turned off after service hours. So that they are possible to be exposed to uncontrolled ambient, which is exceeding the specified temperature/humidity conditions. It is known that paper media loose its stiffness when it is moisturized with high humid air, which degrade stable form feed out of a printer, especially for a cut form printer which feeds papers by friction. Once the Humidity prevention sheet made of a sheet of plastic is placed on the top of the paper stored in the paper cassette, as shown in figure 1, it prevents acclimatization of the paper from the humid air, and maintain good condition till the printer becomes ready for service. This sheet also prevents the paper surface from the foreign materials, such as dust, which helps to improve form feed reliability. In case of ACM, the two different sheets, that correspond to two different size of cut forms are prepared so that each of them covers the entire surface of media except for the space for the pick roller, as shown in the figure 1. 1
