Do you know what I can do to get recto-verso documents correctly scanned by paperwork ?

Thanks in advance. Best regards, Bernard

jflesch commented 10 years ago

Hm, looks like Paperwork needs to set another option for Duplex scanners.

Can you run the following commands and give me the ouput please ?

wget https://raw.githubusercontent.com/jflesch/pyinsane/master/examples/list_all.py -O /tmp/list_all.py
python /tmp/list_all.py

IMPORTANT: I have 2 scanners attached to my computer, the Brother multifunction we are talking about, and an Epson single side flatbed. The scanner to consider is the Brother one, at the begining of the report. This scanner scan the 2 sides in one run, and should output the two scan data in a raw, one after the other... I don't known in which format.

I hope this will help... If you need more test, please let me know... Best regards, Bernard.

I'am not sure, because this option belong to the second part of the dump: concerning my second EPSON scanner not the Brother one. I think the second part of the dump is not relevant because I'am using the brother scanner with paperwork and not the Epson (the brother is duplex, not the epson...)

It looks like paperwork launch the scan, take back the data from the 1st page, and start the analysis... but maybee it should get also the data from the second page right away before starting the analysis. The scanner become available for other tasks (printig, faxing, scanning...) just after paperwork read the first page, and the data from the second page are propably lots at thi time....

I have rerun the dump just after runing paperwork in duplex mode... in case it changed something:

Darn, you are right, I looked at the wrong scanner. Unfortunately, I can't find anything in the documentation of Sane regarding duplex scanners :/ Can you first check it's actually supported by other applications like xsane or simple-scan please ?

nbremond77 commented 10 years ago

Hello Sorry for the delay... I've tried with XSANE 0.998 and it worked. Here is the configuration I have used: capture du 2014-08-21 20 16 21

And when I hit the "Numériser" button, I get 2 PDF files, one for the recto and one other for the verso. I would have prefered one pdf file with 2 pages, but I suppose this is how xsane works with pdf.

Is there any other information I could provide to help you ?

Best regards, Bernard.

jflesch commented 10 years ago

I think I found my mistake. The problem is that when you use the multiscan dialog of Paperwork, it always force the source to the first value that matches what looks like an ADF. I will fix that asap

Hello,

Thanks a lot for the patch, and sorry for the delay, I had to travel.

I tested it with my scanner (Brother MFC-J6920 multifunction scanner printer, dual side) and it worked fine. I was able to scan dual sided A4 pages in on click (almost). Paperwork is a little bit slow but it recognize the 2 sides and perform the OCR on them.

I think your patch corrected the issue.

If I can suggest an improvement,.. maybe you could add an "Number of pages:Auto" mode where paperwork will repeat dual side scanning as long as there is pages in the ADF...

By the way, I have a question: how paperwork behaves when a lot of documents have been scanned and are present in the document folder ?

Anyway, thanks a lot for your work on paperworfk. Best regards, Bernard Rémond

Number of pages:Auto

Just put 9999 pages :)

By the way, I have a question: how paperwork behaves when a lot of documents have been scanned and are present in the document folder ?

I have 941 documents, and it works fine. Is there anything specific you want to know ?

Anyway, since this issue is solved, I'm closing this ticket.
