Reply To: How to get TWCC_PAPERDOUBLEFEED and TWCC_PAPERJAM status

[huanglb]

Thanks. But the triplet returns success for canon 5010C(include 6080, 7580, 9080) while double paper feeded. At that time, GetStatus triplet return 0 as conditioncode, but scanner driver throws out a message box “Double paper feeded … “. Does not it mean that scanner driver can send such a event to the application?

you only need to check the conditionCode when a triplet returns != success
