First, make sure that the printer is plugged in and turned on. Close the output tray extender and rotate the output tray clockwise to stow it in the printer. Open the front door of the printer by tilting it down; the door is just below the LCD screen. Open the cartridge access door by tilting it down; this is behind the front door to the right of the LCD screen. Wait for the cartridge carrier to move into the replacement position.
For pictures of the front door and cartridge access door, see page 79 (page 85 of the PDF) of the manual. HP has the manual on the product support page: https://support.hp.com/us-en/product/hp-officejet-3830-all-in-one-printer-series/7172321/manuals . The current link to the manual is http://h10032.www1.hp.com/ctg/Manual/c04724956 . The doors are also shown in the Setup poster but it isn't as clear.
