Table 1-8 Supported media specifications (continued) *Trays 2 and 3 do not support the range of custom sizes available in Tray 1. **Trays 2 and 3 use custom size, specifically for B5 ISO. Note Use only HP-supported transparencies (HP part number C2934A, Letter size; C2936A, A4 size). Non-supported media Use the following guidelines to avoid poor print quality or damage to your printer: Do not use paper that is too rough. Do not use paper that is embossed or coated unless it is specifically recommended for use in this printer. Do not use paper with cutouts or perforations other than standard three-hole punched paper. Do not use multipart forms.
Do not use paper with irregularities such as tabs or staples. Do not use letterhead paper with low temperature dyes or thermography. Preprinted forms or letterhead must use inks that can tolerate temperatures of 190° C (374° F) for 0.1 second. Do not use any media that produces hazardous emissions, or that melts, offsets, or discolors when exposed to 190° C (374° F) for 0.1 second. Do not use paper that has already been printed on or fed through a photocopier or printer. Do not use paper with a watermark if you are printing solid patterns. Do not duplex on glossy paper. Doing so will result in jams and print-quality problems.
Do not use transparencies that are not specified for use with HP Color LaserJet printers. 30 Printer description C7085-90921 Tray Supported media Media specifications Capacity Tray 3* (optional) Paper A4/Letter Legal Executive JIS B5 Custom (B5 ISO)** Single Sided 2 60 to 105 g/m (16 to 28 lb bond) Two Sided: 2 64-105 g/m (17- 28 lb. bond) 2 500 sheets of 75 g/m (20 lb) paper Transparencies Glossy Paper 0.13 mm (5 mil) 2 120 g/m (32 lb/80 lb text) Limit of 50 transparencies Limit of 500 sheets glossy Duplex printing accessory (optional) Paper A4/Letter Legal Executive JIS B5 2 64 to 105 g/m (17 to 28 lb bond)
