When batches are scanned into Capture, overtime the responsiveness and performance may slow down if scanning in Color at higher DPI settings (e.g. Color Duplex Images at 600DPI) or even when continuously scanning for long periods of time (e.g. 18 continuous hours).
This behavior is due in part to how and when .NET reclaims memory in both PaperVision Capture and PaperFlow. By default, .NET’s garbage collection process (also known as gcCollect) is enabled and set to run every 5 minutes (300 seconds) to reclaim memory no longer being used.
When scanning some very large images or when scanning for long periods of time, it may be necessary to run this process more or less frequently to ensure optimal scanning performance.

When attempting to import certain PDF files into a PaperVision Capture batch, the files are not imported, and no error message is displayed. This is due to the files using an “advanced” PDF format, such as certain text-based PDFs. (Note: image-only PDFs generally do not fall into the advanced PDF category.)
