施乐AirScan / eSCL协议输入源从平面到ADF的转换WorkCentre 3345

Question

我有一个施乐WorkCentre 3345多功能打印机/扫描仪。我声称它支持用于无人驾驶扫描的eSCL协议。，我可以用它扫描到输入源，称为“平面”。问题是，无论我如何尝试，它都不会从'ADF‘输入源中扫描。

我需要发送什么XML才能从ADF扫描？

我可以用下面的XML扫描普莱顿：

<?xml version="1.0" encoding="UTF-8"?>
<scan:ScanSettings xmlns:pwg="http://www.pwg.org/schemas/2010/12/sm"
                   xmlns:scan="http://schemas.hp.com/imaging/escl/2011/05/03">

      <pwg:Width>2560</pwg:Width>
      <pwg:XOffset>0</pwg:XOffset>
      <pwg:YOffset>0</pwg:YOffset>
    </pwg:ScanRegion>
  </pwg:ScanRegions>
  <pwg:InputSource>Platen</pwg:InputSource> <!-- Changing this line to Adf or AdfSimplex does not help!-->

Answer 1

试试下面的一行：

<pwg:InputSource>Feeder</pwg:InputSource>
