三星SCX-4200扫描仪无法正常工作（打印OK）14.04

我不知何故失去了使用Samsung SCX-4200 3in1打印机进行扫描的可能性。 使用初始安装时提供的Linux驱动程序，Priting工作正常，但扫描停顿并失败。

sane-find-scanner显示：

# 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. found USB scanner (vendor=0x0bda [Generic], product=0x0129 [USB2.0-CRW]) at libusb:001:004 # Your USB scanner was (probably) detected. It may or may not be supported by # SANE. Try scanimage -L and read the backend's manpage. # Not checking for parallel port scanners. # Most Scanners connected to the parallel port or other proprietary ports # can't be detected by this program. 

另外，当我尝试scanimage -L时，会显示我网络中的另一台计算机，而不是三星计算机。

 scanimage -L device `hpaio:/net/Deskjet_3520_series?zc=HPC8CBB850038A' is a Hewlett-Packard Deskjet_3520_series all-in-one 

我能做什么？

谢谢。
