Print Media Specifications Printer and Print Media Storage Environment Ideally, the printer and print media storage environment should be at or near room temperature, and not too dry or humid. Remember that print media, such as paper, envelopes or card stock, is hygroscopic; it absorbs and loses moisture rapidly. Heat works with humidity to damage print media. Heat causes the moisture in print media to evaporate, while cold causes it to condense on the sheets. Heating systems and air conditioners remove most of the humidity from a room. As print media is opened and used, it loses moisture, causing streaks and smudging. Humid weather or water coolers can cause the humidity to increase in a room. As print media is opened and used it absorbs any excess moisture, causing light print and dropouts. Also, as print media loses and gains moisture it can distort printouts. This can cause jams. As a result, print media storage and handling are as important as the paper-making process itself. Print media storage environmental conditions directly affect the feed operation. Care should be taken not to purchase more print media than can be easily used in a short time (about 3 months). Print media stored for long periods may experience heat and moisture extremes, which can cause damage. Planning is important to prevent damage to large supply of print media. Unopened paper or card stock in sealed reams can remain stable for several months before use. Opened packages of paper, envelopes or card stock have more potential for environment damage, especially if they are not wrapped with a moisture-proof barrier. The print media storage environment should be properly maintained to ensure optimum printer performance. The required condition is 20° to 24°C (68° to 75°F), with a relative humidity of 45% to 55%. The following guidelines should be helpful when evaluating the storage environment: • Print media should be stored at or near room temperature. • The air should not be too dry or too humid (due to the hygroscopic properties of certain print media). • The best way to store an opened ream of paper is to rewrap it tightly in its moisture- proof wrapping. If the printer environment is subject to extremes, unwrap only the amount of paper to be used during the day operation to prevent unwanted moisture changes. DRIVER AND PRINTER SPECIFICATIONS A.7
