我透過 xsane 或 simplescan 等 GUI 軟體在 Brother DCP-7070DWR、Ubuntu 14.04 上進行掃描時遇到問題
我的印表機透過 wifi 連線。我已成功安裝 Brother 印表機和掃描器的驅動程式。列印效果很好。但我無法掃描 - xsane 告訴我「沒有可用的裝置」（也來自 root）
Scanimage 測試顯示一切正常：
vito@vws:~$ scanimage -d test -T
scanimage: scanning image of size 157x196 pixels at 8 bits/pixel
scanimage: acquiring gray frame, 8 bits/sample
scanimage: reading one scanline, 157 bytes... PASS

這是我電腦上安裝的兄弟的驅動程式：
vito@vws:/opt/lampp/htdocs/qoot$ dpkg -l | grep -i brother
ii brgenml1cupswrapper 3.1.0-1 i386 Brother BrGenML1 CUPS wrapper driver
ii brgenml1lpr 3.1.0-1 i386 Brother BrGenML1 LPR driver

ii brscan4 0.4.3-1 i386 Brother Scanner Driver
ii printer-driver-ptouch 1.3-8 i386 printer driver Brother P-touch label printers
但 sane-find-scanner util 向我展示了一些管道問題：
vito@vws:~$ sudo sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.

不過，我運行了經過評估的 VueScan - 它可以完美地開箱即用。請給我一些如何修復 xsane 工作的想法。
請注意，安裝的 VueScan 掃描軟體運作良好（掃描成功），因此看來不是 IP 位址問題。但是 xsane/simplescan 不起作用，這是一個問題（因為它是免費軟體）
答案1
解決了。使用印表機/掃描器上的選單按鈕取得掃描器的 IP 位址，選擇網絡，然後選擇 TCP / IP，然後選擇 IP 位址。平它：
brsaneconfig4 -p 192.168.0.107
我的情況沒有任何答案。所以我透過 brsaneconfig 設定我的掃描器 IP：
brsaneconfig4 -a name=DCP-7070DW model=DCP7070DW ip=192.168.0.107
然後重新啟動電腦並再次 ping。 Ping 現在運作正常，並且 xsane 成功偵測到掃描器。
