Whenusing paper narrower than 182 x 257 mm (7.2 x 10.1 in.), make sure the weight is greater than or equal to 90 g/m 2 (24 lb bond).Unacceptable paperThe following papers are not recommended for use with the printer:• Chemically treated papers used to make copies without carbon paper, also known as carbonless papers,carbonless copy paper (CCP), or no carbon required (NCR) paper• Preprinted papers with chemicals that may contaminate the printer• Preprinted papers that can be affected by the temperature in the printer fuser• Preprinted papers that require a registration (the precise print location on the page) greater than ±0.09 in.,such as optical character recognition (OCR) forms• In some cases, you can adjust registration with your software application to successfully print on theseforms.• Coated papers (erasable bond), synthetic papers, thermal papers• Rough-edged, rough or heavily textured surface papers or curled papers• Recycled papers containing more than 25% post-consumer waste that do not meet DIN 19 309• Recycled paper having a weight less than 60 g/m2 (16 lb)• Multiple-part forms or documentsFor detailed information, refer to the Card Stock & Label Guide located on the Dell Web site at www.dell.com.guidelines when evaluating new paper stock.Check with the manufacturer or vendor to determine whether the paper you have chosen is acceptable forwithstand these temperatures without discoloring, bleeding, or releasing hazardous emissions.laser printers.
