Scanning using Viper is normally very fast and should take no more than a couple of minutes. On rare occasions - for example when we are extremely busy - your document may be queued for processing. If this happens, you'll see a message to inform you of the delay.
If your document is queued, please check back a little later in the day. Your scan will automatically complete once the queue has cleared - you don't need to re-upload the document or scan it again.
