CAUTION—SHOCK HAZARD: If you are accessing the controller board or installing optional hardware or memory devices sometime after setting up the printer, then turn the printer off, and unplug the power cord from the electrical outlet before continuing. If you have any other devices attached to the printer, then turn them off as well, and unplug any cables going into the printer.
Turn off the printer using the power switch, and then unplug the power cord from the electrical outlet.
Unpack the tray, and then remove all packing materials.
Pull the tray completely out of the base.
Remove any packing material from inside the tray.
Insert the tray into the base.
Place the tray near the printer.
Align the printer with the tray, and then lower the printer into place.
Note: Optional trays lock together when stacked.
Connect the power cord to the printer, then to a properly grounded electrical outlet, and then turn on the printer.
Note: When the printer software and any hardware options are installed, you may need to manually add the options in the printer driver to make them available for print jobs. For more information, see Adding available options in the print driver.
To uninstall the optional trays, slide the latch on the right side of the printer toward the front of the printer until it clicks into place, and then remove stacked trays one at a time from the top to the bottom.
