CAUTION In general do not use paper that is heavier than the media specification recommended for this printer. Doing so can cause misfeeds, paper jams, reduced print quality, and excessive mechanical wear. However, some heavier media, such as HP Cover Stock, can be safely used. Preprinted forms and letterhead Observe the following guidelines for best results with preprinted forms and letterhead: z Forms and letterhead must be printed with heat-resistant inks that will not melt, vaporize, or release hazardous emissions when subjected to the printer's fusing temperature of approximately 190° C (374° F) for 0.1 second. z Inks must be non-flammable and should not adversely affect any printer rollers. z Forms and letterhead should be sealed in a moisture-proof wrapping to prevent changes during storage. z Before loading preprinted paper such as forms and letterhead, verify that the ink on the paper is dry. During the fusing process, wet ink can come off of preprinted paper. z When duplex printing, load pre-printed forms and letterhead into Tray 2 and Tray 3 with the front of the page facing down and the top edge of the page towards the back of the printer. To load pre-printed forms and letterhead into Tray 1, load them with the front of the page facing up and the bottom edge feeding into the printer first. Recycled paper This printer supports the use of recycled paper. Recycled paper must meet the same specifications as standard paper. See the HP LaserJet Family Paper Specification Guide. Hewlett-Packard recommends that recycled paper contain no more than 5 percent ground wood. 78 ENWW
