Lexmark C950 manual Storing paper, Unacceptable paper examples

Paper and specialty media guide 78

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:

1Minimize paper consumption.

2Be 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.

3Choose the most appropriate paper for printing needs: normal 75 or 80 g/m2 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 paper

•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/m2 (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%. 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.
