The laser-printed sheets should be mailed in envelopes. The envelopes should have an edge or end seam and a minimum basis weight of 24 lb (90 g/m2). 2 3 2 Guidelines for using media 17 4 Print bar codes in advance and presort all envelopes. Meter the envelopes or use precanceled stamps. (In addition to helping in the overall performance of the laser-printed document, bar coding and presorting can offer advantageous postal charges. In the United States, please contact your United States Postal Service business office to find out more about this. ) Avoid text-on-text contact. This can be avoided by printing on only one side, and then folding the document with the fold to the outside. Text then contacts only the inside of the envelope or the back side of the printed sheets. If text-on-text contact cannot be avoided, use a thin insert such as onion skin to separate the printed sheets for best results. Ensure that all mailpieces are placed in a tray and presented at the retail window or, in the United States, at the Bulk Mail Acceptance Unit (BMAU). Avoid placing laser-printed mail into collection boxes or chutes. 5 6 18 Using print media ENWW Shipping and storing print media The performance of HP LaserJet printers depends on the condition of the print media that is used. This section contains recommendations for shipping and storing media, and provides information about environmental effects on media. Shipping media When you are shipping print media through different environments, use plastic wrap to wrap all cartons on the shipping pallet. When you are shipping media across bodies of water, also wrap individual cartons. Packaging must protect the media from physical damage. Storing media Follow these guidelines when stacking and storing print media: q Do not store cartons or reams directly on the floor. Place cartons on a pallet or on shelves. Do not store individual reams in a manner that will result in curling or warping. Rewrap partially used packages of media before storing them. Do not stack more than six cartons on top of each other. Stack each carton squarely on top of the one underneath. Do not place anything on top of media, regardless of whether the paper is packaged or unpackaged. Store envelopes in a protective box to avoid damaging the envelope edges. Keep stored media away from extremes in temperature and humidity. [. . . ] Paper is often packaged and sold in reams. simplex Printing on one side of a sheet of paper. smoothness Surface smoothness is determined by measuring the rate of air flow between the sheet surface and a flat reference surface.
