To ensure the best print quality and feed reliability, use 75 g/m2 (20 lb) xerographic paper. Business paper designed for general business use also provides acceptable print quality. Only use paper able to withstand high temperatures without discoloring, bleeding, or releasing hazardous emissions. The laser printing process heats paper to high temperatures. Check with the manufacturer or vendor to determine whether the paper you have chosen is acceptable for laser printers. Always print several samples before buying large quantities of any type of print media. When choosing any print media, you should consider the weight, fiber content, and color. Unacceptable Paper The following paper types are not recommended for use with the printer: l Chemically treated paper used to make copies without carbon paper, also known as carbonless paper, carbonless copy paper (CCP), or no carbon required (NCR) paper. l Preprinted paper with chemicals that may contaminate the printer. l Preprinted paper that can be affected by the temperature in the fuser. l Preprinted paper that requires a registration (the precise print location on the page) greater than ±0.09 inches, such as optical character recognition (OCR) forms. In some cases, you can adjust registration with your software program to successfully print on these forms. l Coated paper (erasable bond), synthetic paper, and thermal paper. l Rough-edged, rough or heavily textured surface paper, or curled paper. l Recycled paper containing more than 25% post-consumer waste that does not meet DIN 19 309. l Multiple-part forms or documents. l Print quality may deteriorate (blank spaces or blotches may appear in the text) when printing on talc or acid paper. Selecting Paper Proper paper selection helps prevent jams and ensures trouble-free printing. To help avoid jams or poor print quality: l Always use new, undamaged paper. l Before loading the paper, identify the recommended print side of the paper. This information is usually indicated on the paper package. l Do not use paper that you have cut or trimmed. l Do not mix print media sizes, weights, or types in the same source. This may result in a paper jam. l Do not remove the tray while a job is printing. l Ensure that the paper is properly loaded in the tray. l Flex the paper back and forth, and then fan them. Straighten the edges of the stack on a level surface. Selecting Preprinted Forms and Letterheads When selecting preprinted forms and letterhead paper for the printer: l Use grain long paper for best results. l Use only forms and letterheads printed using an offset lithographic or engraved printing process. l Select paper that absorb ink, but does not bleed. l Avoid paper with rough or heavily textured surfaces. l Use paper printed with heat-resistant inks designed for use in xerographic copiers. The ink must withstand temperatures of 225°C (437°F) without melting or releasing hazardous emissions. l Use inks that are not affected by the resin in the toner or the silicone in the fuser. Inks that are oxidation-set or oil-based should meet these requirements; latex inks might not. If you are in doubt, contact your paper supplier. Printing on a Letterhead
