Having trouble with LNScan? For specific problems you can use email contact.

Hint: If something does not work with LNScan, please try to scan with some other application, for example the Imaging for Windows. Maybe you'll find out that the "error" is "feature" of the scanning environment.

Here is a list of FAQs.
Q: Why is the direct scanning NOT working on my scanner ? What can I do ?
A: Some scanners just ignore this TWAIN setting, so there's nothing we can do about this. Sad, bud true.

Q: I can't scan multiple images when my scanning environment is opened. It is automatically closed after I scan one image!
A: Yes, that's annoying! Please check if you can scan multiple images in some other application. Some (mostly HP) scanning software does not allow to scan multiple images at one time even though a TWAIN compatible scanner software should allow that.

Q: Each time my scanning environment window is opened, default settings are preset. It bothers me!
A: That's why we've added DPI and Colors presetting to LNScan. Again, some scanning software ignores this; if that's your case, use the adjust-after-scanning option.

Q: Do I need Lotus Notes client installed on the machine with LNScan?
A: If you want to scan from LotusNotes, yes. But, though LNScan was designed to work mainly for LotusNotes, it can be used in other applications as well, as long as they allow calling dll functions (VisualBasic, VisualC++, Delphi etc.).

Q: Can I store scanned pictures on the server as well as into a local database?
A: Yes, LNScan is controlled from LotusScript, so you have access to all Lotus Notes resources.

Q: I get "Operation error" when I run the new version of LNScan.
A: Try to re-select scanner again, and/or check if you have permission to write in the temp folder where LNScan creates files.

Q: Why is LNScan now a DLL ?
A: It's better to have a dll with functions you can call from LotusScript; you have the power of control.

Q: Why there is not a function in LNScanLib script library for "Scan 10 images and 10 documents are created" ?
A: It requires a lot of information to specify how new documents should look and where they should be created. The server, database, form, field names, field types, field values, consider all these needed items as parameters in some function - you get the conclusion: too many. You can call the function ScanToImages repeatedly to "scan 10 images" and then "create 10 documents" with your own LotusScript or formula. Have a look into the dllnscan.nsf demo database for ideas.

Sad facts:
1. When scanning with "HP precision scan" we found out, that the settings (dpi, colours) are forget when it's closed after scanning. Our client wanted settings to be preset to grayscale and 150DPI. We adjusted LNScan to do that, and when the scanner environment opened, settings were preset ok. But, when we put the paper into scanner's document feeder, a new window opened and 200 DPI was preset again(!). After we contacted HP, they told us that in previous versions of HP precision scan the settings were remembered, but they've changed it, because, as they said, "The users demanded NOT TO REMEMBER SETTINGS" :-)

2. Normal scanning environment use the preview scanning in low resolution - allowing user to select an area the user wishes to scan. Not like the HP Precision scan LT ! Clicking on "Start scanning" scans whole scanner bed with high resolution, which takes looong time. Then it lets user select an area, and then it just transfers the corresponding data to the calling application and closes itself (!). Now does anybody understand why it closes itself instead of letting user to select-and-transfer another area ? Please e-mail to azhanel@lnscan.com if you know why-o-why it (mis)behaves like that. Anyway, this method could work on fast scanners, yeah. But with HP ScanJet 3200 it's really upside down logic; or is there some weirdo tester working in HP ?:-)

3. LotusNotes can't properly handle 1 bit-per-pixel image pasted into richtext field as picture. It seems to ignore it's palette - so it's sometimes inverted. When you switch colors in the palette, nothing happens :-). But when you create an attachment from such image - it's displayed properly - even with notes viewer.
