无法连接到扫描仪(简单扫描和 Brother DCP-L2530DW)

无法连接到扫描仪(简单扫描和 Brother DCP-L2530DW)

我正在使用 Brother DCP-L2530DW 打印机/扫描仪的简单扫描功能。打印机运行正常,但我使用扫描仪时遇到问题。

我已经安装了驱动程序:

jam@jam-ncase:~$ sudo dpkg -l | grep Brother
[sudo] password for jamie: 
ii  brscan-skey                                0.2.4-1                                amd64        Brother Linux scanner S-KEY tool
ii  brscan4                                    0.4.8-1                                amd64        Brother Scanner Driver
ii  dcpl2530dwpdrv:i386                        4.0.0-1                                i386         Brother DCP-L2530DW printer driver (lpd/cups)
ii  printer-driver-brlaser                     5-1                                    amd64        printer driver for (some) Brother laser printers
ii  printer-driver-ptouch                      1.4.2-3                                amd64        printer driver Brother P-touch label printers

当我启动简单扫描时,它显示Ready to Scan - Brother DCP-L2530DW

但是当我单击扫描时,扫描动画开始,但随后弹出一条错误消息:Failed to scan, unable to connect to scanner

我已经在 Google 上搜索过该问题,并且尝试过以下方法:

  • 将我的用户添加到lp

  • 运行此命令:sudo cp /usr/lib64/sane/libsane-brother* /usr/lib/x86_64-linux-gnu/sane

这对兄弟 MFC-L2710DW 的 Ubuntu 20.04 系统很管用

sudo apt purge ippusbxd
