Installing the Optional Tray Module
CAUTION: If you are adding an optional 250-sheet tray module or 500-sheet tray module after setting up the printer, be sure to turn off the
printer, unplug the power cable, and disconnect all cables from the back of the printer before completing these tasks.
Optional tray modules attach under the standard 250-sheet tray module and only one additional tray can be added.

Some instructions may vary depending on the tray module configuration in your printer.
NOTE: Some tray module configurations differ from those described in this manual.
1. Unpack the tray and remove all packing material and tape.
2. Place the tray module in the location that you would like the printer to be located.
NOTE: You will place the printer on the tray in a later step.
3. Turn off the printer.
4. If there are any trays already attached to the printer, unlock the tray from the printer by removing the tray from the tray module and turning the locking
mechanism, inside the printer, as shown in the graphic.
5. Remove the printer from the tray.
CAUTION: Lift the printer with two people, one facing the front of the printer (operator panel side) and the other facing the back. Never try to lift
the printer while facing its right and left side.
