有人知道如何将扫描仪 Ricoh P311 连接到 Ubuntu Server 上的 SANE 吗？我尝试过使用默认设置的 SANE，在 SANE 上尝试过 Airscan，还访问过 Ricoh 的官方网站，但找不到适用于 Ubuntu/SANE 的驱动程序！当我 ping 扫描仪的 IP 时，数据包丢失率为 0%！

No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages).
