我正在尝试让我的 HP Officejet 8020 在 Kubuntu 20.04 上进行扫描，但我一直收到错误：
error: SANE: Error during device I/O (code=9)
我已经运行了 hp-check，一切似乎都很好，我按照HP LaserJet AllInOne，无法进行扫描，但无济于事。我重新安装了 HPLIP，包括发现应用程序和 HP 网站上的最新版本。我安装并重新安装了 hp-plugin，但似乎没有任何效果。以下是 hp-check 的输出：

Does anyone have any ideas?
答案1
我在 Ubuntu 18.04 中遇到了同样的错误。我通过以下方式解决了它：
- 下载脚本https://developers.hp.com/sites/default/files/hplip-3.22.2-plugin.run（链接直接指向文本文件）
- 保存
- 在终端中运行命令
sh hplip-3.22.2-plugin.run。
最后，我可以用 hp-scan 进行扫描了。
