Paper and specialty media guide
•
Do not use paper that has been cut or trimmed by hand.
•
Do not mix paper sizes, types, or weights in the same tray; mixing results in jams.
•
Do not use coated papers unless they are specifically designed for electrophotographic printing.
Selecting preprinted forms and letterhead
Use these guidelines when selecting preprinted forms and letterhead:
•
Use grain long for 60–90‑g/m
•
Use only forms and letterhead printed using an offset lithographic or engraved printing process.
•
Avoid paper with rough or heavily textured surfaces.
Use inks that are not affected by the resin in toner. Inks that are oxidation‑set or oil‑based generally meet these
requirements; latex inks might not.
When in doubt, contact your paper supplier.
Using recycled paper and other office papers
As an environmentally conscientious company, we support the use of recycled paper produced specifically for
use in laser (electrophotographic) printers.
While no blanket statement can be made that all recycled paper will feed well, we consistently test papers that
represent recycled cut size copier papers available on the global market. This scientific testing is conducted
with rigor and discipline. Many factors are taken into consideration both separately and as a whole, including
the following:
•
Amount of post-consumer waste (We test up to 100% post-consumer waste content.)
•
Temperature and humidity conditions (Testing chambers simulate climates from all over the world.)
•
Moisture content (Business papers should have low moisture: 4–5%.)
•
Bending resistance and proper stiffness means optimum feeding through the printer.
•
Thickness (impacts how much can be loaded into a tray)
•
Surface roughness (measured in Sheffield units, impacts print clarity and how well toner fuses to the paper)
•
Surface friction (determines how easily sheets can be separated)
•
Grain and formation (impacts curling, which also influences the mechanics of how the paper behaves as it
moves through the printer)
•
Brightness and texture (look and feel)
Recycled papers are better than ever; however, the amount of recycled content in a paper affects the degree
of control over foreign matter. And while recycled papers are one good path to printing in an environmentally
responsible manner, they are not perfect. The energy required to de-ink and deal with additives such as
colorants and "glue" often generates more carbon emissions than does normal paper production. However,
using recycled papers enables better resource management overall.
We concern ourselves with the responsible use of paper in general based on life cycle assessments of its
products. To gain a better understanding of the impact of printers on the environment, the company
commissioned a number of life cycle assessments and found that paper was identified as the primary contributor
(up to 80%) of carbon emissions caused throughout the entire life of a device (from design to end-of-life). This
is due to the energy-intensive manufacturing processes required to make paper.
Thus, we seek to educate customers and partners on minimizing the impact of paper. Using recycled paper is
one way. Eliminating excessive and unnecessary paper consumption is another. We are well-equipped to help
