05-04-2005, 15:50 sgriffin@dataworksplus.com Joined on 06-23-2004 Posts 1 ADF I am trying to tell if an adf has paper loaded in the tray using v14 with VB6.  I am using the following code to get the feeder status: Set oTwainCap = New LEADTwainCapability oTwainCap.CapInfo.ConType = L_TWON_ONEVALUE oTwainCap.CapInfo.Capability = L_CAP_FEEDERLOADED m_oRasterTwain.EnableMethodErrors = False intRet = m_oRasterTwain.GetCapability2(oTwainCap, _                                                                 L_LTWAIN_CAPABILITY_GETCURRENT) This code always returns a true value.  The feeder enabled property is set to true.  Any suggestions? Thanks    Report

When I test it in Twacker it also returns true, regardless of the existance of paper or not. I am using v15 with .NET C#. My scanner is a Xerox 510 DocuMate. Has anyone found a solution to this?    Report
