Change Staples
With Finisher
Open the compartment that contains the staple tray by opening the door marked in the image.
Pull the marked handle towards you, which will cause the staples tray to appear in the left hand side of the tray you just pulled out.
The staples tray can now be removed by pushing the green piece on the tray upwards. After that, it is possible to pull out the tray.
The new staple tray can now be inserted back by pushing it back into the slot. Then push the green piece back into its previous position which will lock the tray. Then push the larger tray containing the staples tray back in and close the door to the compartment. Check the printer screen to see if the staples have been changed successfully. If there is a warning, something went wrong, otherwise everything should be fine.
