Recycled papers are better than ever; however, the amount of recycled content in 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.
Lexmark concerns itself 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, Lexmark seeks 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. Lexmark is well-equipped to help
customers minimize printing and copying waste. In addition, the company encourages purchasing paper from suppliers
who demonstrate their commitment to sustainable forestry practices.
Lexmark does not endorse specific suppliers, although a converter’s product list for special applications is maintained.
The following paper choice guidelines will help alleviate the environmental impact of printing:
1
Minimize paper consumption.
2
Be selective about the origin of wood fiber. Buy from suppliers who carry certifications such as the Forestry
Stewardship Council (FSC) or The Program for the Endorsement of Forest Certification (PEFC). These certifications
guarantee that the paper manufacturer uses wood pulp from forestry operators that employ environmentally and
socially responsible forest management and restoration practices.
3
Choose the most appropriate paper for printing needs: normal 75 or 80 g/m
2
certified paper, lower weight paper,
or recycled paper.
Storing paper
Use these paper storage guidelines to help avoid jams and uneven print quality:
•
For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40%. Most label
manufacturers recommend printing in a temperature range of 18 to 24°C (65 to 75°F) with relative humidity between
40 and 60%.
•
Store paper in cartons when possible, on a pallet or shelf, rather than on the floor.
• Store individual packages on a flat surface.
• Do not store anything on top of individual paper packages.
Data security notice
This printer contains various types of memory that are capable of storing device and network settings, information
from embedded solutions, and user data. The types of memory, along with the types of data stored by each, are
described below.
• Volatile memory—This device utilizes standard Random Access Memory (RAM) to temporarily buffer user data
during simple print and copy jobs.
•
Non-volatile memory—This device may utilize two forms of non-volatile memory: EEPROM and NAND (flash
memory). Both types are used to store the operating system, device settings, network information, scanner and
bookmark settings, and embedded solutions.
