Prior to replacing or disposing of your defective unit, follow these instructions to ensure the right accessories are removed.
a) Cartridges. Make sure that the unit is plugged in and turned on before removing the print cartridges.
NOTE: If the cartridges are not going to be inserted in the replacement product immediately, please store them at room temperature inside a rigid sealed plastic container. Store the color cartridge with the nozzles DOWN and the black cartridge with the nozzles UP. This will help prevent ink from drying out.
Then, unplug the printer and keep the following accessories:
b) Bezel panel
c) ADF input tray
d) Duplexer (Automatic two-sided printing accessory)
After removing the duplexer accessory, please remember to install the rear access door on the defective unit before it is returned to HP.

i) Phone cord
j) Ethernet cord
