♦ Acid paper and neutralized paper
Paper can be classified as either acid paper or neutralized paper.
Though modern paper manufacture methods started with acid paper, recently neutralized
paper is taking the place of acid paper because of environment or preservation issues.
However, many forms of acid paper can be found in recycled paper.We recommend that
you use neutralized paper for this printer.
You can use an acid paper check pen to distinguish acid paper from neutral paper.
♦ Print surface
The characteristics may differ a little between the face side and reverse side of a sheet of
paper.
Usually, the opening side of the ream of paper package is the print side. Follow any
indication of the print side on the paper package. Typically, the paper side is indicated with
an arrow.
♦ Moisture content
Moisture content is the amount of water left in the paper after manufacture. It is one of the
important characteristics of the paper. This can change greatly depending on the storage
environment, although usually paper contains around 5% water by weight. Because
paper often absorbs water, the amount of water can sometimes be about 10% in a high
humidity environment. When the amount of water increases, the characteristic of the
paper changes greatly. The fixing of the toner may become worse. For storage of the
paper and during use, we recommend the humidity of the surrounding environment is
between 50 % and 60%.
