To help avoid jams or poor print quality: • Always use new, undamaged paper. • Before loading paper, know the recommended print side of the paper you're using. This information is usually indicated on the paper package. • Do not use paper that you have cut or trimmed yourself. • Do not mix paper sizes, weights, or types in the same paper source; mixing results in jams. • Do not use coated papers. • Do not remove trays while a job is printing or Busy is displayed on the operator panel. • Make sure the Paper Type, Paper Texture, and Paper Weight settings are correct. (See Paper Menu for detailed information about these settings.) • Make sure the paper is properly loaded in the paper source. • Flex paper back and forth. Do not fold or crease the paper. Straighten the edges on a level surface. Choosing envelopes When printing on envelopes: • To achieve the best possible print quality, use only high-quality envelopes that are designed for use in laser printers. • Use only new, undamaged envelopes. • Load only one size of envelope at a time in the multipurpose feeder. • Make sure the glue is not exposed. • Do not use envelopes that contain moisture or high humidity. Moist envelopes or envelopes containing high humidity (over 60%) may become sealed from the high fuser temperature. • Be sure to select MP Feeder as the paper source in the Paper Menu and set the correct envelope size. The laser printing process heats envelopes to a temperature of 165°C (329°F). Use only envelopes that are able to withstand these temperatures without sealing, excessive curling, wrinkling, or releasing hazardous emissions. If you have any doubts about the envelopes you are considering using, check with the envelope supplier. 36
