Error SendDatCapability

[marius8612]

Hi everyone,

I have a problem with DSM working with my printer/scanner hp lj 475dw. The method returns sts BADVALUE after calling ThreadToCallerWaitOne() in public virtual STS DatCapability(DG a_dg, MSG a_msg, ref TW_CAPABILITY a_twcapability).

Before the call to ThreadToCallerWaitOne() sts in ThreadData m_threaddata is “SUCCESS” but after “BADVALUE”.

Anyone has any idea about the problem?

Thank you very much!

Sorry, there wasn’t much info to go on in the message, it finally occurred to me that this might be a question about TWAIN C#. If still interested, the code and the DSM can be used to produce logs to analyze what’s happening. However, in most cases one needs to go right to the scanner vendor for answers…
