OOPS - I didn't click on the page. Then I had acccess to the image menu. THANKS! Old: I set the scanner to greyscale and scanned. The image icon at the top was greyed out. Is that the image menu you mentioned? If I change the left side from Greyscale to Black & white, I don't see a window to change white / black threshold.
You'll need to click the image to select it, then you can use the menu.

You can also try "Document Correction" under the Image menu.
I think that it is all about the drivers and the post processing of the scanned document. Did you check for a more recent driver? Also, is there a more recent firmware update for the Epson printer?
I'm testing naps2 and found one strange bug: when scanning b/w documents (printed previously by laser printer on common office paper), background in scanned images is not white, but rather "blue-ish". When I change color settings to b/w, background is "grey". No matter what I try with settings, it is still the same. But when I use original app, scanned documents look much better, with nearly white background (printer/scanner epson xp-830). How could I fix this?
The scanner is not recognised. I have the firmware file 1300_0C26.nal. Where do I have to put it so NAPS2 will use it? It should show up in the SANE section in NAPS2.
You can also scan in either color or grayscale, then after the scan, under the "Image" menu, click "Black and White" to convert to pure black & white for a small file size. This window will let you pick the exact white/black threshold and preview the results to make sure it's right.
That's because you are scanning in Black and white mode and not in gray scale. There is always some compromise as the scanner has to use some kind of threshold where it decides to show the pixel or not. Try gray scale.
I am using NAPS2 with a Brother MFC-L2700DW scanner. I want to scan tax documents - black text on a white background. But I get speckles / dots in white areas. Yes, the glass is clean. And if I do a color image, I don;t get the dots - but do get a much larger file size. Sometimes there's text on the back of the page that I think is 'tricking' it. Is there a way to set things so it knows - really dark area is black. lighter areas are all white? ie how to make monochrome scans crisper? Black text and...
suggestion for improvement - integrate icc Scanner Profiles
Scanning is functional, but no scanned pages appear in the Control Center window
I'm sorry, but no, that doesn't help. I didn't notice the Use native UI button before, so I tried it. "Native UI" leads me to expect the UI (and the controls) I get when I configure the scanner through its own software, but I don't get that. The UI looks the same as when the Use predefined settings button is selected. The initial dialog is the same except that Use native UI disables the Brightness and Contrast controls. I haven't tried to compare the Advanced dialog with and without Use native UI,...

Autonaming fails
You are welcome.
YESSS, thank you very much, TWAIN driver is not installed by default, but I could do it. And definition is OK now. Thanks again.
Hi Jonathan, You should be able to click the pencil button to open the profile settings and select the "Use Native UI" radio button instead of "Use predefined settings" to get the Brother TWAIN/WIA/whatever interface to appear; and allow you to scan in duplex like you would in any other windows program if you have the Brother scanner driver installed. I believe they removed the native scan interface from the manufacturer and are using a standard one in the program for all scanners to make things...

I came here to report the same problem, and found this ticket instead. I edited my profile to specify the TWAIN interface, however, and I still see no duplex option. There's a "Flip back sides of duplex pages" option, but no way to select duplex in order for it to matter. I'm running Windows 11 Enterprise. NAPS2 is v8.2.1.0. My device is a Brother MFC-J6540DW. I'll check back in a few days, and if there's no response, it won't matter. I need a utility that can scan duplex now. NAPS2 is the most highly...
Try to install and then use the Twain driver. The via drivers may not have all the features implemented.

Hello, Naps2 (8.2.1.0) works almost perfectly on my W11 PC. I only have one problem : I have only one profile, with 500 PPP. In the main window, I also typed 500. Scanned image stays with 300. I tried with mac quality in the profile, no change. I don't understand what the problem is. BTW printer is a Brother MFC-J4340DW using WIA.
I believe these users are also running into the same issue: https://sourceforge.net/p/naps2/discussion/general/thread/4e092704/
Program interface lacks duplex option.
Hi, When running NAPS via the CLI, is there any argument I can use alongside --noprofile in order to flip duplexed pages? Just curious if this setting was only available via creating a profile and then specifying that profile in the CLI. Thanks in advance.
Would also bump a request for double-sided ADF. I've just replaced my Surface and discovered the HP software isn't compatible with the ARM processor in the Surface.
I run NAPS2 v. 8.2.1 on Linux Mint 22.3, scanner Canon DR-F120 connected via sane-utils v. 1.2.1-7build4. Bit depth: 24 bit color. When scanning a document containing red colored items, these items are green in the scanned PDF. How comes? What can I do to correct this? In Windows (same NAPS2 version, same scanner , here with Twain driver) everything is correct. Thanks for any help! Harald
Dialing in NAPS2 settings for Canon CanoScan LiDE 120
Hi, I am coming from PaperPort as I need something much more lightweight for my current needs. however I have two questions:- 1) Can you scan to a folder on a network share and where are the settings/controls to do this as I can't find anything in settings relating to a path. 2) I tried to create a profile and connect to my Brother ADS-1600w wireless scanner. It cannot find the scanner on the network so I entered the IP address and either Port 80 or Port 443 as possible ports but it won't connect....

Hallo liebe Gemeinde, habe mir gerade die Software runtergeladen weil ich sowas schon längere Zeit gesucht habe. Hätte da nun mal eine spezielle Frage dazu. Da mein Drucker bzw. Scanner keine Vorder und Rückseiten scannen kann, ich aber einige Dokumente habe die 2 und mehre Seiten haben, nun meine Frage. Wie gehe ich da vor und was muß ich machen damit ich bei Dokumenten mit mehreren Seiten alle in eine Datei scannen kann. Ich will bzw. ich möchte natürlich bei einem Dokument mit 5 Seiten nach dem...
Error NAPS2 Tries Scanning Too Many Pages
Good day! Can I ask? Is there a way that we can auto remove the blank scanned page? or we just manually delete it? or can I suggest adding a button on the main screen "removeblankedpage". Thanks!
Hi all, Using a Neat ND-1000 I can get scans into NAPS2. But they come in backwards if I auto-save to PDF. Feature request: Add a "Reverse Order?" checkbox option in the profile under Auto-Save. *Expected behavior mimics a manual Reorder->Reverse All(N) operation in the app. *
Hi all. Just installed NAPS2 after a PC switch and realizing that Neat has basically abandoned the ND-1000 ADF scanner unless I pay $150 for their cloud warez. Good times... Bump on the request for double-sided ADF. I know I can do an interleave in the reorder tool, so this helps.
I have the same issue. NAPS2 does not always crash, but quite often. It happens when saving a scanned document as PDF file.
Turns out it does actually work using the OEM UI ("Use native UI"), so not a big deal! A hint like "try again with native UI" might be nice if the exception is triggered :-)
