Duplicate output images for one scan #85

Closed chiponline89 closed 3 years ago

Hi, Currently, I have an issue when using scanner "HP scanjet Enterprise Flow 7000 s3" to scan.

Duplicate images output for one scan. I receipted 2 same images for 1 page. And 4 images (2 same images of first page and 2 same images of back page) if duplex scan.

Could you help me about this issue?

Thank you so much!

Hello, @chiponline89 Perhaps this is due to the fact that you are subscribing twice to the event of receiving the image.

Hello, @saraff-9EB1047A4BEB4cef8506B29BA325BD5A

I also dowloaded example in this link : https://saraff-9eb1047a4beb4cef8506b29ba325bd5a.github.io/sarafftwain/ -> Run it -> I got same issue in my computer
After, I run one more time with this code in other computer -> I not got this issue.

=> I think that maybe the main reason is driver of scanner

I will try uninstall this driver and reinstall it
