I OUTLINE hp Color 9850mfp OUTLINE OF SYSTEM 1.6 Media specifications Before purchasing large quantities of print media, make sure that it meets the requirements specified in this service manual and in the HP Color 9850mfp System Administrator Guide. Always test the print media before buying large quantities. Hewlett-Packard neither warrants nor recommends the use of a particular brand of paper or print media other than HP media. Media properties are subject to manufacturing changes, and HP has no control over such changes. Although testing the media helps to characterize the performance and the manufacturer s process quality, the customer assumes all responsibility for the quality and performance of media. CAUTION Using print media that does not meet HP specifications might cause problems for the printer, requiring repair. Such repair is not covered by the Hewlett-Packard warranty or service agreements. The HP Color 9850mfp accepts a variety of media, such as cut-sheet paper, labels, and customsize paper. Properties such as weight, composition, grain, and moisture content are important factors affecting printer performance and output quality. Media that does not meet the guidelines outlined in this manual and in the print media guide can cause the following problems: z poor print quality z increased jams z premature wear on the printer, requiring repair Note Guidelines for selecting media Selecting media by type and size at the control panel and in the MFP must be selected prior to print/copy. Using the wrong setting can result in unsatisfactory print quality. Always print by type for special print media such as labels. Some print media might meet all of the guidelines in this manual and still not produce satisfactory results. This might be the result of improper handling, unacceptable temperature and humidity levels, or other variables over which HP has no control. If you are unsure what type of paper you are loading (such as bond or recycled), check the label on the package of paper. z See Basis weight field test on page 1-15 for information about measuring basis weight. z See Caliper field test on page 1-17 for information about measuring caliper. z See Paper finish field test on page 1-17 for information about smoothness. Hint Do not purchase more media than can be easily used in a short time (about 3 months). Media that is stored for long periods experiences heat and moisture extremes that can be damaging. Planning is important to prevent damage to a large supply of media. 1-9
