A: Hi there Chetan,
Thank you for submitting this question.
In response to your query, I can confirm the following:
Push Scan - You scan directly from the machine
Pull Scan - You put the document on the scanner, then go back to your PC to set the scan location.
If you'd like a little more information in relation to this, we have a news post on this topic that may help you: http://www.printerbase.co.uk/news/what-is-the-difference-between-pull-and-push-scanning/
I hope that this helps, Chetan.
