그래서 내 인쇄 스캐너 Samsung SCX-4300은 USB를 통해 제대로 작동하고 대신 다음 링크와 같이 "네트워킹 USB 서버"에 연결했습니다.
서버를 통해 인쇄는 제대로 작동하지만 스캐너는 작동하지 않으며 Ubuntu 튜토리얼의 지침을 따랐습니다.

1.그래서 터미널에 이렇게 썼습니다 sudo service saned restart.
Failed to restart saned.service: unit saned.service is masked
2.나중에, sudo service saned status:
● saned.service
Active: inactive (dead)
Loaded: masked (/dev/null; bad)
그러던 중 인터넷을 뒤지다가 이런 웹사이트를 발견했습니다.systemctl, 마스크 해제 방법
삼. file /lib/systemd/system/saned.service:
/lib/systemd/system/saned.service: symbolic lik to /dev/null
4.확인하려고 입력했는데 sudo nano /run/systemd/generator.late/saned.service완전히 비어 있는 것을 발견했습니다.
5. sudo rm /lib/systemd/system/saned.service그리고 나중에,sudo systemctl daemon-reload
7.그리고 마지막으로, systemctl status saned:
● saned.service - LSB: SANE network scanner server
Loaded: loaded (/etc/init.d/saned; generated)
Active: failed (Result: exit-code) since Sun 2019-06-16 13:19:23 -05; 9min ago

8:그래서 다시 확인하러 갔습니다 sudo nano /run/systemd/generator.late/saned.service.

서버를 통해 스캐너를 연결하는 문제를 해결하는 방법을 찾을 수 없습니다.
그렇다면 이 오류를 해결하는 방법을 아는 사람이 있나요?
