Other Paper Specifications
Porosity: The density of the paper fibers
Stiffness: Paper must be stiff enough or it may buckle in the machine, causing jams.
Curl: Most paper naturally tends to curl after the package is opened. When paper passes through the fixing unit,
it curls upward slightly. To deliver flat printouts, load the paper so that the curl faces towards the bottom of the
paper tray.
Static electricity: During printing, paper is electrostatically charged so that the toner adheres. Choose paper
that can be discharged quickly so that copies do not cling together.
Whiteness: Paper whiteness affects print contrast. Use whiter paper for sharper, brighter copies.
Quality: Machine problems may occur if sheet sizes are not uniform or if corners are not square, edges are
rough, sheets are uncut, or edges or corners are crushed. In order to prevent these problems, be especially
careful when you cut the paper yourself.
Packaging: Choose paper that is properly packaged and stacked in boxes. Ideally, the packaging itself should
have been treated with a coating to inhibit moisture.
