Installing a 250-sheet or 500-sheet drawer
Optional drawers attach under the printer and optional duplex unit. The printer automatically recognizes any drawer that is
installed.
A drawer consists of a tray and a support unit. The 250-sheet drawer and the 500-sheet drawer are installed the same way.
1
Remove the tray from the support unit. Remove all packing material and tape from both the support unit and the
tray.

2
Place the support unit on top of any previously installed drawers, or the table or printer cabinet where you plan to
use the printer.
The tab, round peg, and square holes on top of any drawer help you position the support unit so the edges are
aligned properly. Make sure the support unit is securely in place.
3
Attach another optional drawer, a duplex unit, or the printer.
You can attach a label to the trays to indicate the tray number.
