Mail merge and Staple with a Canon iR ADV DX C5550i

[Saturn]

One of our customers wants to print exam questions on a Canon iR ADV DX C5850i using WinWord's mail merge function.

The exam consists of approximately 10 pages.
There are up to 20 candidates for each exam.
The candidate data is stored in an Excel spreadsheet.
Each page should contain the exam code, last name, first name, candidate number, and exam date.
When printing, the pages should be stapled together for each candidate.

I haven't found a way to do this with the driver settings, as WinWord sends the entire job as a single print job.
Do you know a way of how to do this? Any suggestion is appreciated.

we must use the mailboxes on the canon for each user, then indicate on the photocopieur how we want to print and staple in corners afterwards
