Forums › TWAIN Classic › EZTWAIN TWAIN_SetThreshold error
Hi,
When using the EZTWAIN toolbox in combination with a HP ScanJet 5470c the TWAIN_SetThreshold() value is ignored. This value – used for B&W scans – should be between 1 (light) and 256 (dark), but on the HP scanner the input is ignored. On a Canon Lide60 scanner this works great. HP appears to be incompatible with this TWAIN command.
Does anyone know where to look to get the HP scanner working properly? The HP software and firmware are the latest versions.
Regards, Gerrit
