Technical procedure during scanning

To be able to quickly isolate a scanning problem, it is important to understand the technical procedure used during scanning.

Here are the main steps of the procedure:

• The user starts the scan on the device. This starts a workflow instance of the selected workflow.

• The DeviceService starts the scan, i.e. the feeding of the paper (not the client on the device).

• The device generates the image file as a TIFF or JPG (depending on the device manufacturer) regardless of the desired target format.

• The device stores the image file in the WorkflowFiles share on the server via SMB (or FTP if this is explicitly set). The username and password for accessing the share are obtained by the device from the system area to which the device is assigned.

• The file transfer may take a maximum of 4 minutes. After that, the procedure is automatically canceled.

• The ImageService makes the file changes included in the workflow (e.g. OCR processing, image processing).

• If a directory is specified as the destination, the DeviceService stores the file there. For access, it uses the user running the ImageService application pool or the user specified in the module. If the destination is an e-mail mailbox, the notification service sends the file.

• After passing the end module, all temporary files are deleted. The workflow instance is still retained so that the procedure remains visible for Tracking Workflows.
