Changing the Default HP ADF Scanning Resolution

Posted on 2012-08-22
Last Modified: 2013-12-15
One of our Remote Offices has a HP M1212nf printer, which they use to Scan to PDF, the issue is the at the PDF files are too large when using the ADF. The default resolution is 300dpi and this is just to high, especially when 99% of what is being scanned are black/white documents that really only need 256 grayscale, at 50% scaling size and 100 to 150dpi. When you choose to use the ADF to scan instead of the flatbed, it defaults to 300dpi and I'm unable to change it. I even tried the XP built in scanner software and it does the same thing.

Any ideas?  I thought to install our Adobe Acrobat X Standard, but if I understand correctly it will just use the HP Twain Driver as well, so same issue

    also, Its running HP Scanning Ver, and I've already update the drivers which didn't update the Scanning software, not sure where I can get a more recent version of the HP Scan software that would work with this printer, as I did do a google search and HP Support site search with not much luck.

    OR even if I could get HP Scan To:  software to turn off the Preview option when using the ADF, then perhaps it would let me change the resolution and other settings before I scan. but I don't see how I can turn that off

    Hi Cathy,
    300 DPI is a fine resolution for B&W docs – it's what I use nearly all of the time, and works very well for creating B&W searchable PDF docs with OCR. The issue is color mode. The reason the docs are so large is that the color mode is likely 24-bit or 32-bit color, which combined with 300 DPI, makes a very large file. Grayscale (8-bit) would be better, but for typical B&W business docs, B&W (1-bit) color mode is fine.

    I don't have that scanner (or the HP scanning software), but since you're willing to install Acrobat X, that should work for you. Yes, it uses the TWAIN driver, but you should be able to set the parameters and have them be "sticky". Try this in Acrobat X Standard:

    PDF from Scanner
    Configure Presets...

    You will see a dialog box like this:
    Acrobat X Standard - Configure PresetsYou should be able to set the parameters (presets) and Save them. As mentioned above, for typical B&W business docs, I recommend Resolution of 300 DPI and Color Mode of Black and White. Note the check-box for <Make Searchable (Run OCR)>. I always set this option for subsequent indexing and searching by a third-party search tool, but it takes more time than simply creating an image (bitmap). On some docs, you may need a Color Mode of Grayscale, in which case I recommend a Resolution of 150 or 200 DPI, which will keep the file size reasonable but still provide for good OCR accuracy.

    I decided to give the Adobe Acrobat a try since I did have a license available and to my surprise it does have another drivers to use other than the Twain, So when using the WIA driver I'm able to change the settings and pre-set them and it appears to work when scanning using the flatbed. OCR is not necessary but I see its options.  As this is a remote site,User is very busy right now on jobsites and unable to stay and test using ADF feeder. I hope to test at the first of the week.

    I generally prefer TWAIN over WIA, but for some of my scanners, WIA works better. Whenever I deploy a new scanner, I always test both TWAIN and WIA (and ISIS if it has one) to see which driver performs better. Regards, Joe

    Using Adobe Acrobat appears to have solved the problem, though we have not thoroughly tested, but User is just to busy so they will its up to him.  thank you for you input. I still find it fustrating that the HP Twain software would be so restricted with using the ADF to scan with.
