Scan Document

I confirm that I can upload regular files (including PDFs) from my phone to Dropbox, and I can scan into JPG files and upload them.

It's only the PDF scanning option that isn't working, as far as I can tell. I suspect that the cause is the OCR post-processing...

We are having the same issue, every time we attempt to scan in a document as a pdf, the blue bar indicates its fully uploaded but it just freezes at 100% and the file does not appear in dropbox. We've noticed this problem before and normally we would re-scan the item or restart the app and it would upload fine but now nothing is working. We use an s22 ultra.

I keep getting a glitch when attempting to create a document through the Dropbox "Scan Document" feature. I can scan the document, make adjustments, etc, but once I hit "Save" it gets stuck with the message 'Waiting to Upload".

I've been working on this for about an hour, attempted about a dozen scans. Sometimes the blue progress bar appears, moves to the right, then goes back to the message "Wating to Upload". Sometimes it will cycle through this a few times, sometimes it just stays on the "Waiting to Upload" mesage.

I'm only using 12.9% of a 2 TB account, and Dropbox is updated to the newest version. I'm using an iPhone 8 Plus with iOS 11.2.5. I have about 180GB avialble space on my iPhone. I can upload documents to Dropbox from other apps on my iPhone, they sync just fine. Camera Uploads is turned On, and syncing photos and videos just fine.

It would be useful for a field tech to occasionally be able to scan a document into a survey123 record. This could provide a copy of a physical document that could be handled and formated as a pdf from beginning to end inside of the survey.

Good Day to you,

I love this idea because when you take a photo with a phone, for in place of a scan, these [scanned] images need higher resolution than Survey123 automatically sets up for, and if you bump up the resolution, it's bumped for all photos and will increase your cloud data quicker. So, adding an option for scans (even if you take the picture with your phone) could be set up differently, so you choose the resolution for the scans and a choice for photos.

I went to camera|settings|scene optimizer|Scan documents and text, to disable then re-enable it, but didn't make a difference. If I take a picture of a receipt, then view it from the camera app, I get the little Extract Text button, so that works fine. But no option to scan a document.

In Windows, if a WIA driver is installed for your scanner, you can use the Scan button to create a PDF. Press the Scan button, then select Adobe Acrobat from the list of registered applications in Windows. Then, select a scanner and a document preset or Custom Scan in the Acrobat scan interface.

If you specify that you want to use the Show scanner's user interface instead of the Acrobat user interface, other windows or dialog boxes appear. Consult the scanner documentation information on available options. In Mac OS, the scanner user interface is always shown.

Select this option only if you want to see the settings using the windows and dialog boxes provided by the scanner manufacturer. When the option is not selected, scanning starts directly with the settings specified in the Custom Scan or Configure Predefined Settings interface.

You can scan both sides of pages even on scanners that do not themselves support two-sided scanning. When Both Sides is selected, a dialog box appears after the first sides are scanned. You can then reverse the original paper documents in the tray, and select the Scan Reverse Side (Put Reverse Of Sheets) option in that dialog box. This method produces a PDF with all pages in the proper sequence.

Select a basic color mode (Autodetect, Color, Black and White, or Grayscale) that your scanner supports. This option is enabled if your Scanner Options are set to use the Acrobat scanning dialog box instead of the scanner application.

Select this option to run the optimization process on the PDF. This option is used to compress and filter the images in the scanned PDF. Select the Settings icon to customize optimization with specific file compression and filtering settings.

Select this option to convert text images in the PDF to searchable and selectable text. This option applies optical character recognition (OCR) and font and page recognition to the text images. Select the Settings icon and specify settings in the Recognize Text - Settings dialog box. View Recognize text in scanned documents.

When selected, the Document Properties dialog box appears after scanning. In the Document Properties dialog box, you can add metadata, or information about the scanned document, to the PDF file. If you are creating multiple files, you can enter common metadata for all the files.

The Enhance Scanned PDF dialog box controls the image settings of how scanned images are filtered and compressed for the PDF. Default settings are suitable for a wide range of document pages, but you may want to customize settings for higher-quality images, smaller file sizes, or scanning issues.

Divides each page into black-and-white, grayscale, and color regions and chooses a representation that preserves appearance while highly compressing each type of content. The recommended scanning resolutions are 300 dots per inch (dpi) for grayscale and RGB input, or 600 dpi for black-and-white input.

Acrobat scanning accepts images between 10 dpi and 3000 dpi. If you select Searchable Image or ClearScan for PDF Output Style, an input resolution of 72 dpi or higher is required. Also, input resolution higher than 600 dpi is downsampled to 600 dpi or lower.

Lossless compressions can only be applied to monochrome images. To apply lossless compression to a scanned image, select one of these options under the Optimization Options in the Optimize Scanned PDF dialog box: CCITT Group 4 or JBIG2 (Lossless) for monochrome images. If this image is appended to a PDF document, and you save the file using the Save option, the scanned image remains uncompressed. The scanned image may be compressed if you save the PDF using Save As.

For most pages, black-and-white scanning at 300 dpi produces text best suited for conversion. At 150 dpi, OCR accuracy is slightly lower, and more font-recognition errors occur; at 400 dpi and higher resolution, processing slows, and compressed pages are bigger. If a page has many unrecognized words or small text (9 points or smaller), try scanning at a higher resolution. Scan in black and white whenever possible.

If your scanner has a manual brightness control, adjust it so that characters are clean and well-formed. If characters are touching, use a higher (brighter) setting. If characters are separated, use a lower (darker) setting.

You can use Acrobat to recognize text in previously scanned documents that have already been converted to PDF. Optical character recognition (OCR) software enables you to search, correct, and copy the text in a scanned PDF. The original scanner resolution must have been set at 72 dpi or higher to apply OCR to a PDF.

When you run OCR on a scanned output, Acrobat analyzes bitmaps of text and substitutes words and characters for those bitmap areas. If the ideal substitution is uncertain, Acrobat marks the word as suspect. Suspects appear in the PDF as the original bitmap of the word, but the text is included on an invisible layer behind the bitmap of the word. This method makes the word searchable even though it's displayed as a bitmap.

Note: If you try to select text in a scanned PDF that does not have OCR applied or try to perform a Read Out Loud operation on an image file, Acrobat asks if you want to run OCR. If you select OK, the Text Recognition dialog box opens, and you can select options described in detail under the previous topic.

I resolved this same issue by running simple-scan --debug from the terminal; the document feeder error disappeared, and now I can simply launch the application from the menu without problems. Maybe it resetted some config file, dunno. Hope it helps you.

Also, on that note, you will need an OCR program to convert the scanned image to text.

I have had impressive results with Tesseract - on Linux it works quite well as a command-line utility, and on Windows there is a program called FreeOCR which uses the Tesseract engine to recognize the characters.

I have used it in my office for the electronic filing of a great number of older procedure documents only available on paper from before the introduction of our document management system.

In order to scan your documents, you will need access to a computer and scanner or a smartphone with an internet connection. If you do not have access to these, common places with this type of equipment are libraries, community centers, internet cafs, and copy shops. Note: If you choose to use a public computer, be sure to delete your scanned documents once you have finished uploading them.

Unless specifically directed to do so by the National Visa Center (NVC) please do not mail any documents to NVC. If you do, you will delay the processing of your case and risk losing any documents you send.

Include a certified translation of your document with your original (i.e. foreign language) document in a single file. Please note that a translation is not required for documents in the language of the country where your visa interview will take place.

Be clear, easily seen and read, and no parts of the document are cut off.

Most scanning programs offer a preview function so you can make sure the document is easily read. If you cannot read the scanned document, re-scan it at a higher resolution. Keep in mind this means the saved file will be larger and you may need to compress the file before you upload it.

The attachment field type will allow you to attach multiple files directly to your records, including mp3s, PDFs, photos, and word documents. The attachment field looks like this in the expanded re... ff782bc1db
