The printer has the following trays:
1 Tray 1 (multipurpose tray) with extending paper support
2 Tray 2 (250-sheet tray)
3 Optional Tray 3 (500-sheet tray)
Task 4 – 19

Using media types

The printer control panel can be configured so that the printer draws certain media types from specific trays. This enables you, in the printer driver, to select media by type rather than by tray (source). Selecting media by type helps prevent accidental printing on special or expensive media. For example, if a tray is configured for letterhead, and you specify in the driver to print on plain paper, the printer will not accidentally print on letterhead from the letterhead tray. For more information on using the printer control panel to set the size and type of media for the input trays, see the online user guide.
CAUTION Hewlett-Packard recommends using HP Color LaserJet
Transparencies (C2934A for letter-size and C2936A for A4-size) for optimum printing results. Do not use DeskJet (inkjet) or monochrome transparencies in your printer. The transparencies can become overheated and melt, causing serious damage to your printer.
