Use Web Scanner

This topic provides user instructions for the Transact Web Scanner. The Web Scanner securely scans images into Ephesoft Transact from your client machine and supports both HTTP and HTTPS protocols. Images can be stored on the local system or on the server.

Transact Web Scanner is certified to function with TWAIN-compliant scanners and their drivers. Manufacturer drivers that are not fully TWAIN-compliant may experience interoperability issues.

If you have not yet installed Web Scanner, complete the instructions provided in Web Scanner installation before proceeding.

Web Scanner user interface

The Web Scanner user interface contains three panels:

  • Thumbnail Stack: Contains a stack of images.
  • Thumbnail List: Displays thumbnails of the images.
  • Full Image: Displays the image selected from the Thumbnail Panel
Web Scanner user interface

The following navigation icons display in the toolbar:

  • First page (<<)
  • Previous page (<)
  • Next page (>)
  • Last page (>>)

Further zoom and rotation functionalities are also available in the toolbar.

Create and configure scanner profiles

Specific profile configurations are available to optimize Web Scanner functionality. Each batch class contains a default Web Scanner profile. We recommend adding additional customized profiles to accommodate specific document types and batch classes.

To create and configure a scanner profile, complete the following steps.

Administrator permissions are required.

  1. From the left sidebar, select Scanner Profiles and click Add.

  2. Specify a Profile Name.

    If a field in the Scanner Profiles configuration screen is missing or invalid, the field will display in red. See Change scanner profile settings for a table of fields available for customization, and their customized values.

  3. Click Deploy. The scanner profile is completed.

Operating the Web Scanner

The Web Scanner scans documents directly into Transact for batch class processing. Follow these steps to use the Web Scanner.

  1. Open the Transact home page and click Scan New Documents under the Operator menu.

  2. Click the drop-down arrow and select the appropriate batch class for the documents being scanned.

  3. If you are using multiple scanners, select the desired scanner from the drop-down menu.

  4. Click Start to start scanning and importing the images.

  5. After all the pages are scanned, click Finish.

  6. Click OK to complete the scan.

Key features

Here are key features of the Transact Web Scanner:

  • Delete multiple images: You can delete multiple images by selecting one image at a time while holding the Ctrl key.

  • Rescan a page on the Review/Validation screen: If errors occur while scanning, you are provided with an option on the Review and Validation screens to rescan the selected page.

  • Viewing and organizing multiple thumbnails: Thumbnails can be dragged and reordered according to your viewing preferences.

  • Renaming batch description: You are provided with an option to edit the Scan folder name.

  • Client-side image generation: This feature generates the .jpg files to display on the client's side. This displays colored images on the user interface. To toggle between uploading to the client vs. server side, utilize the switch provided in the application.properties file found within the META-INF folder.

Page number label

In the Thumbnail panel, a page number is shown under each image thumbnail. Each label begins with PG and is followed by the image count, beginning with PG 0. To start the page counter at PG 1, change the page_identifier_start_from_1 switch value to True. Refer to the Change scanner profile settings for more information about changing the settings.

Page navigation shortcut

To move between the images in the Thumbnail panel, use the shortcuts provided:

  • Next page: Ctrl+P or Right Arrow key.

  • Previous page: Ctrl+Shift+P or Left Arrow key.

To view details for these shortcuts, select More > Shortcuts.

Troubleshooting

Web Scanner caching

The temp folder in the Transact scanner service directory is hidden to ensure additional security of processed data. It can be found in the following location by typing temp in the search bar:

C:\Program Files (x86)\EphesoftTransactScannerService\temp

Subfolders are created for each scanning job in the temporary folder. The name of each subfolder consists of two parts:

  • User ID of the operator running the scan

  • Numeric value generated from time and date

This subfolder contains scanned files and their thumbnails.

Multiple user error

Two users with the same username are not allowed to log in from the same server or from any other client machine.
