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.
However, 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.
Unacceptable paper examples
Test results indicate that the following paper types are at risk for use with laser printers:
• Chemically treated papers used to make copies without carbon paper, also known as carbonless papers
• Preprinted papers with chemicals that may contaminate the printer
• Preprinted papers that can be affected by the temperature in the printer fuser
•
Preprinted papers that require a registration (the precise location on the page) greater than ± 2.3 mm (± 0.9 in.),
such as optical character recognition (OCR) forms. In some cases, registration can be adjusted with a software
application to successfully print on these forms.)
•
Coated papers (erasable bond), synthetic papers, thermal papers
•
Rough-edged, rough or heavily textured surface papers or curled papers
•
Recycled papers that fail EN12281:2002 (European testing)
• Paper weighing less than 60 g/m
2
(16 lb)
• Multiple part forms or documents

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 percent. Most
label manufacturers recommend printing in a temperature range of 18–24°C (65–75°F) with relative humidity
between 40 and 60 percent.
•
Store paper in cartons, 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.
•
Take paper out of the carton or wrapper only when you are ready to load it in the printer. The carton and wrapper
help keep the paper clean, dry, and flat.
