Brother WLAN 扫描仪 DCP-7055W 无法工作（“无效参数”）

我无法通过 WLAN 让 Brother DCP-7055W 的扫描仪工作。我已经安装了 Brother 的官方驱动程序，打印机本身工作正常。

我已将扫描仪设置为使用静态 IP 地址 (192.168.002.150)。使用 Brother 的扫描仪，brsaneconfig4我按如下方式添加扫描仪（使用002而不是2以下这个提示)：

brsaneconfig4 -a name=DCP-7055W model=DCP-7055W ip=192.168.002.150

扫描器 ping 操作正常：

$ brsaneconfig4 -p
test DCP-7055W
ping 192.168.002.150 -w 10

PING 192.168.002.150 (192.168.2.150) 56(84) bytes of data.
64 bytes from 192.168.2.150: icmp_req=1 ttl=255 time=9.21 ms
64 bytes from 192.168.2.150: icmp_req=2 ttl=255 time=5.67 ms
64 bytes from 192.168.2.150: icmp_req=3 ttl=255 time=6.01 ms
64 bytes from 192.168.2.150: icmp_req=4 ttl=255 time=3.33 ms

我还确保64 位驱动程序的问题已修复：

$ ls -l /usr/lib/sane/libsane-brother4*
lrwxrwxrwx 1 root root     35 Sep 25 07:18 /usr/lib/sane/libsane-brother4.so -> /usr/lib/sane/libsane-brother4.so.1
lrwxrwxrwx 1 root root     39 Sep 25 07:18 /usr/lib/sane/libsane-brother4.so.1 -> /usr/lib/sane/libsane-brother4.so.1.0.7
-rwxr-xr-x 1 root root 129376 Sep 25 07:18 /usr/lib/sane/libsane-brother4.so.1.0.7

我还根据以下规定修复了 UDEV 规则这个答案：

$ grep saned /lib/udev/rules.d/40-libsane.rules 
ENV{DEVTYPE}=="usb_device", MODE="0664", OWNER="root", GROUP="saned"

但是，我实际上无法扫描：无论我尝试使用什么工具，都会出现以下错误：

$ scanimage -T
scanimage: open of device brother4:net1;dev0 failed: Invalid argument

无论是普通用户还是使用时都会发生这种情况sudo，因此这不应该是权限问题。

我错过了什么？

更新 1：现在有一些更详细的调试输出：

# SANE_DEBUG_BROTHER4=255 scanimage
[sanei_debug] Setting debug level of brother4 to 255.
[brother4] brother init

更新2：我现在也尝试通过 USB 使用扫描仪。我收到相同的错误（“无效参数”），但在扫描过程的稍后阶段：

# SANE_DEBUG_BROTHER4=255 scanimage -T
[sanei_debug] Setting debug level of brother4 to 255.

ABrother 扫描仪常见问题解答提到这可能是由于扫描区域太小，但传递-x 100 -y 100给scanimage不会改变任何东西。我还尝试明确传递scanimage -h扫描仪返回的所有其他参数，但没有成功。

安装libsane-extras，如建议在这里没有改变任何东西。

继类似问题的故障排除，我已经跑了

# strace -o strace.out -f scanimage -T

输出的末尾有以下内容：

4019  ioctl(151, USBDEVFS_SUBMITURB or USBDEVFS_SUBMITURB32, 0xbfbfe0a8) = -1 ENOENT (No such file or directory)
4019  gettimeofday({1387487538, 170759}, NULL) = 0

4019  exit_group(4)                     = ?

整个日志充满了ioctl引用USBDEFVS_SUBMITURB和获取的调用No such file or directory。但是，我对 Linux USB 内部机制了解不够，无法理解这一点。

更新 3：我的内核：

# uname -r
3.2.0-57-generic-pae

相关输出来自dmesg：

[10210.399432] usb 1-1: usbfs: interface 0 claimed by usblp while 'scanimage' sets config #1
[10210.399446] usb 1-1: usbfs: process 5347 (scanimage) did not claim interface 1 before use

答案1

尝试下面的链接；

问题 ：

-name=Scanner---adding type brother
-name=SCANNER_DCP770CW

我的兄弟型号为 MFC-J430W。

答案2

看来 Brother 驱动程序 .deb 包将 sane 驱动程序安装在 Ubuntu 16.04 的错误目录中。请尝试以下操作：

  1. 复制所有文件/usr/lib64到/usr/lib

    sudo cp /usr/lib64/* /usr/lib

  2. 复制所有文件/usr/lib64/sane到/usr/lib/x86_64-linux-gnu/sane或者/usr/lib/sane

    sudo cp /usr/lib64/sane/* /usr/lib/sane

    sudo cp /usr/lib64/sane/* /usr/lib/x86_64-linux-gnu/sane
