Twain problem with Ricoh 2020D scanner

[Guest]

Hi people,

I have a great problem: I have a Ricoh 2020D multifunction device and it works fine but not the scanner.

I give you some facts of our special infrastructure:
All our PC's are virtualized by Citrix and this server is at point A and the terminal with the Ricoh device at point B. The 2 networks have different IP areas and are connected via VPN. So I decided to use the scnhosts file to tell the PC's at point A that the scanner is at point B.
But it doens't work. I also called the Ricoh support and they said it hast to work.
Can you help me to solve this annoying problem?

Thanks in advance.

From this post I will guess that you are trying to scan via the Network TWAIN. This ONLY works on the SAME IP subnet that the PC and Copier reside on. So the Citrix session being on a different IP address structure cannot see the copier via its local IP address using SNMP communication. This is in the manual somewhere.

ScanRouter Lite ( no longer supported by Ricoh since 2006 ) could give you access via the local PC "IF" your citrix session can see the local PC HDD.

I don't remember if this unit has a HDD itself, and Web Image Monitor. But in weird situations like this I have done a STORE FILE from the scanner menu and then browsed into the web page of the MFP, Document server, and downloaded the file.....

Hi Ralph,

first thanks for your advice. But the terminals have no local HDD. It is a IGEL Thin Client. Sorry that I didn't mentioned it.
The Ricoh support said to me that the TWAIN driver works in 2 different networks because they tested it for me. In this case you have to use the scnhosts file located a bit deeper in the TWAIN folder (C:\WINDOWS\twain_32\).

Can you please explain this a bit more? I didn't really understand what you do

OK, I don't think I have had that need before... Learn somthing new every day....after 24 years in the biz.

As to the DOC server stuff. If the MFP has a HDD, from scanner mode select Store file, and store only. Put in or select a user name and a file name. Scan the original as if you were sending to email or folder. On a PC, use the web browser to open the Web Image Monitor, go to Doc Server and you should see your file. If it is downloadable you can select PDF or TIF and it will open the file in an appropriate viewer in your browser. Then you can save the file to any place yo uhave right to.

On Older MFP's you need to open the properties of the image in Doc Server and then you can select the down load as... function.

Just a way arround more secure or stubborn networks.
