Twain and Stop button

Product Name: All DocuMate Scanners
Operating System: Windows 10 x64

Dear Madam or Sir,

I am developing an application that interacts to Documate 4799 using Twain.

After starting scanning from my GUI, I press the STOP button in the scanner(green one).

Last two scannings show as empty, but most important, it stops immediately, leaving pages inside.

Then if I start scanning again, it reports PAPER JAM.

How could I interact with the scanner so when STOP button is pressed the user does not have to potentially clean PAPER JAMS and continue scanning?

pd: I tried the same with OneTouch 4.6, being able to archieve paper jams most of the times.

I have read in the manuals it should be compatible with Twain 1.9. I can tell that when sending the triplet:


It says not implemented. Which one should I use instead to be able to pause and resume the scanning process using TWAIN from the computer?


Thanks in advance for your answer.  Joaquim Raurell Martí
