Note Testing media specifications The following tests describe ways to make sure that the media meets the specifications listed in this manual and the HP LaserJet Printer Family Print Media Guide. See "Tools and suppliers" on page 49 for help in obtaining tools to perform these tests. Basis-weight field test The basis weight should be indicated on the ream label. If the label is not available, a simple field test can identify the basis weight of paper. The basis weight of paper is equal to the weight of 2000 sheets of paper, or four full reams. Weigh a full ream on a postal scale and then multiply that weight by four. Or, weigh 10 sheets of paper, divide that weight by 10, multiply by 2000, and then divide by 16. Amount 4 reams 1 ream 10 sheets Formula weight = basis weight weight x 4 = basis weight (weight divided by 10) x 2000 and then divided by 16 = basis weight Example: 10 sheets weigh 1.6 ounces 0.16 ounce x 2000 = 320 ounces 320 ounce ÷ 16 ounce/lb = 20 lb paper 44 Installation ENWW
