5022-xxx Unacceptable media The following media types are not recommended for use with the printer: • Chemically treated media used to make copies without carbon paper, also known as carbonless papers, carbonless copy paper (CCP), or no carbon required (NCR) paper • Preprinted media with chemicals that may contaminate the printer • Preprinted media that can be affected by the temperature in the printer fuser • Preprinted media that requires a registration (the precise print location on the page) greater than ±2.3 mm (±0.09 in.), such as optical character recognition (OCR) forms In some cases, registration can be adjusted with a program to successfully print on these forms. • Coated media (erasable bond), synthetic media, thermal media • Rough-edged, rough, or heavily textured surface media, or curled media • Recycled media containing more than 25% post-consumer waste that does not meet DIN19 309 • Media weighing less than 60 g/m2 (16 lb) • Multiple-part forms or documents Selecting media Using appropriate media prevents jams and helps ensure trouble-free printing. To help avoid jams and poor print quality: • Always use new, undamaged media. • Before loading media, know the recommended print side of the media. This information is usually indicated on the media package. • Do not use media that has been cut or trimmed by hand. • Do not mix media sizes, types, or weights in the same source; mixing results in jams. • Do not use coated media unless they are specifically designed for electrophotographic printing. Selecting preprinted forms and letterhead Use these guidelines when selecting preprinted forms and letterhead: • Use grain long papers for best results for 60 to 90 g/m2 weights. • Use only forms and letterhead printed using an offset lithographic or engraved printing process. • Avoid papers with rough or heavily textured surfaces. Use papers printed with heat-resistant inks designed for use in xerographic copiers. The ink must be able to withstand temperatures up to 180°C (356°F) without melting or releasing hazardous emissions. Use inks that are not affected by the resin in toner. Inks that are oxidation-set or oil-based generally meet these requirements; latex inks might not. When in doubt, contact the paper supplier. Preprinted papers such as letterhead must be able to withstand temperatures up to 180°C (356°F) without melting or releasing hazardous emissions. General information 1-7
