HP LaserJet AllInOne，扫描不工作

Question

如果我尝试扫描(xsane或简易扫描)，就会得到以下输出：

设备URI: hpaio:/net/HP_LaserJet_MFP_M129-M134?hostname=hp-drucker

我听说这个设备有很好的linux支持。请参阅https://hardwarerecs.stackexchange.com/questions/8323/small-printerscanner-with-very-good-support-for-ubuntu

在更新snmp包之后，我现在得到了这个错误：

仍然不可能扫描:-(

Answer 1

有些蛮力的答案是，您已经在您的系统上安装了snmp，并且它还没有被完全删除。最简单的修复方法是重新安装snmp：

打开终端，输入命令

sudo apt update
sudo apt install snmp snmp-mibs-downloader

修复了snmp问题后，hp扫描引用的I/O错误9似乎表明它可能没有完全安装-请参阅https://bugzilla.redhat.com/show_bug.cgi?id=1347231。

若要修复此问题，请输入命令

sudo apt install --reinstall hplip

Answer 2

我通过安装error: SANE: Error during device I/O (code=9)解决了hplip-plugin问题。

我必须手动从那里下载它并使用sh hplip-3.19.3-plugin.run安装它(使用与您自己的hplip相同的版本，您可以通过运行命令hp-info查看版本号)。使用hp-plugin命令对我不起作用。

在此之后，hp-scan和像简单扫描这样的程序正常工作。

Answer 3

遇到了类似的问题，我的hp-扫描器的错误信息非常相似(它在hp-all-one中，打印机工作，但扫描仪不能工作)。

对原始帖子的直接回答没有解决我的问题，但是安装hplip，然后运行hp-设置，使我的hp-扫描仪完美地工作。
