Installing the 2 x 550-sheet tray
CAUTION—SHOCK HAZARD: To avoid the risk of electrical shock, if you are accessing the controller
board or installing optional hardware or memory devices sometime after setting up the printer, then turn
the printer o, and unplug the power cord from the electrical outlet before continuing. If you have any
other devices attached to the printer, then turn them o as well, and unplug any cables going into the
printer.
Notes:
• This option must be installed together with an optional 550‑sheet tray. Place the option at the bottom of
the
configuration.
• If a 550‑sheet tray is already installed, uninstall the tray, remove the tray side cover, remove the lower
tray cover, and then place the tray on top of this option.
• This task requires a flat‑head screwdriver.
1 Turn o the printer.
2 Unplug the power cord from the electrical outlet, and then from the printer.
