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)

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.
