私のプリント スキャナー Samsung SCX-4300 は USB 経由では正常に動作していますが、代わりに次のリンクのように「ネットワーク USB サーバー」に接続しました。
サーバー経由では、印刷は正常に動作しますが、スキャナーは動作しません。Ubuntu のチュートリアルの指示に従いました。

1.そこで私はターミナルに次のように書きましたsudo service saned restart:
Failed to restart saned.service: unit saned.service is masked
2.後で、sudo service saned status：
● saned.service
Active: inactive (dead)
Loaded: masked (/dev/null; bad)
その後、インターネットで調べたところ、次の Web サイトを見つけました。systemctl、マスク解除方法
3. file /lib/systemd/system/saned.service:
/lib/systemd/system/saned.service: symbolic lik to /dev/null
4.確認するために入力してみたsudo nano /run/systemd/generator.late/saned.serviceところ、完全に空であることがわかりました。
5. sudo rm /lib/systemd/system/saned.serviceそしてその後、sudo systemctl daemon-reload
7。そして最後に、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:そこでもう一度確認してみましたsudo nano /run/systemd/generator.late/saned.service。

サーバー経由でスキャナーを接続するための修正方法が見つかりませんでした。
それで、この障害を修正する方法を知っている人はいますか?
