The toner collection container collects excess toner
                  that is produced during printing. When the toner collection container becomes
                  full, the message "Replace toner collection container." will appear.
Replace the toner collection container as instructed by the
                  message in the touch panel.
When the key is tapped, instructions for replacing the toner
                  collection container will appear. Follow the instructions. When
                  the toner collection container is replaced, the message will automatically
                  disappear.
