When replacing the toner cartridge, the cartridge tray gets stuck and the door will not completely drop down if the paper tray is set to a media size longer than Letter/A4.
- Apply downward pressure to the front door while simultaneously lifting the cartridge tray.
- Push the cartridge tray back into the printer until it frees itself.
- Lift the front door carefully.
- Remove the tray before completely lowering the front door.
Note: When replacing toner cartridges, always remember to remove the paper tray if the tray guides are set to any media longer than Letter/A4 before opening the front door.
