Check and prepare envelopes before loading Check and prepare envelopes before loading Before you load envelopes, it is important to check and prepare the envelopes. You can load envelopes in all paper trays and the special feeder. IMPORTANT • Do not print on the back side of the envelopes (the side with the flap). • Do not load the following types of envelopes. This can cause a paper jam, dirty printed output or dirty machine parts: • Curled, creased, or folded envelopes • Very thick or thin envelopes • Damp or wet envelopes • Torn envelopes • Irregularly shaped envelopes • Envelopes with clasps or windows • Envelopes that are already sealed • Envelopes with holes or perforations • Envelopes with specially coated surfaces • Envelopes made of surface treated colored paper • Envelopes that are self-adhesive and use ink, glue, or other substances that can melt, burn, vaporize, or emit smells by the heat of the fixing unit (approximately 200°C). Melted glue can cause sealed envelopes. • When there is a temperature difference between the storage location and the location where the envelopes are printed, take the envelopes to the print location on time. CAUTION • When you handle paper, be careful not to cut your hands on the edges of the paper. • Do not store paper in places exposed to open flames. This can cause the paper to ignite which could result in burns or a fire.
