5055-xxx Media guidelines Paper Following are media guidelines for successful printing: • Rough, highly textured, limp or pre-curled papers will result in lower print quality and more frequent paper feed failures. • Colored papers, treated and preprinted papers, letterhead and labels must be able to withstand 338° F (170° C) fusing temperature. • Preprinted forms and letterhead should be selected using guidelines found in the printer User's Guide. The chemical process used in preprinting may render some papers unsuitable. • Unsuitable papers include multipart forms and documents; chemically treated papers; coated, synthetic, and thermal papers; and preprinted papers requiring a high degree of registration. • Recycled paper less than 21 lb (80 g/m2) may cause unacceptable results. Envelopes • Envelopes should be fed long edge first, with flap trailing. • When the finisher is attached, only long-edge fed envelopes wider than 5.8 in. (148 mm) feed direction dimension may be used. To print smaller envelopes, the finisher must be undocked during the job. • If envelope wrinkling occurs, refer to the User's Guide for correct weight, type, loading and stacking of envelopes. • All envelopes should be new, unused and without package damage. • Envelopes with excessive curl or twist exceeding 0.12 in. (6 mm), stuck together, with bent corners or nicked edges or those that interlock should not be used. 1-20 Service Manual
