The printer has the following trays:
1Tray 1 (multipurpose tray) with extending paper support
2Tray 2 (250-sheet tray)
3Optional 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.
CAUTIONHewlett-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) ormonochrome transparencies in your printer. The transparencies
can become overheated and melt, causing serious damage to your
printer.
