MFP Multifunction peripheral; also known as multifunction product or multifunction printer. mils One mil equals 0.001 inches. moisture content How much moisture print media will absorb or lose, depending on the humidity in the surrounding air. Paper is hygroscopic, that is, it will absorb or lose moisture depending on the humidity in the air around it. The moisture content of paper has a great effect on its resistivity. Paper will absorb moisture in a high-humidity environment and lose moisture in a low humidity environment. Small increases in moisture content greatly reduce resistivity while small decreases in moisture content greatly increase resistivity. Moisture content can also affect other paper properties such as curl, stiffness, and dimensional size. Higher moisture content can make paper prone to curl and wrinkling during printing, make a sheet limp, and increase the dimensions of a cut sheet. Paper performance can change significantly with seasonal or weather changes, which affect the humidity in the printing environment. packaging Packaging is an important consideration when using paper in an HP LaserJet printer, because adequate packaging maintains the correct level of moisture and protects paper from damage during transport and storage. perforations A hole or series of holes punched through the paper to aid in the separation of one piece of paper from another. pH Refers to the acidity/alkalinity of paper as determined by the TAPPI (Technical Association of the Pulp and Paper Industry) cold-extraction method. photocopy paper See copier paper. post-consumer waste Manufactured material that the customer has used. Post-consumer waste can be office paper, mail, used boxes, old newspapers, or magazines. pre-consumer waste Material that never reaches the customer after it has been manufactured. Pre-consumer waste can be unused paper stock, bindery trimmings, envelope cuttings, business forms, or unsold books or magazines. print media Paper, envelopes, cardstock, overhead transparencies, and labels that are used with printers. Print media used in HP LaserJet printers must meet the guidelines and specifications listed in this guide. ream A ream is a quantity of 500 sheets of paper. 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. Smoothness usually is expressed in Sheffield or Bekk units. stiffness How resistant print media is to bending or flexing. A minimum stiffness is required in order for paper to separate from the rollers inside of the printer. Most longgrain papers that are heavier than 60 g/m2 will have adequate stiffness to transport through the printer. Generally, stiffness increases with paper weight. 42 ENWW
