Scan to network folder only works for first page

[tmsvl]

Hello,

I'm observing some weird behavior with my Officejet Pro 9010. 

I have configured "Scan to network folder" to scan to a Synology NAS in my network. This works perfectly. 

However, from the moment I scan more than one page at once (e.g. two-sided original, or two pages after each other):

- The printer throws an error after 10-15 seconds: "Cannot write to \\fileshare\Scans. This folder is read-only, has the wrong permissions or is no longer available." (free translation from Dutch :))

- The *first* page of the scan does appear in the network folder; the subsequent pages don't reach the NAS.

Has anyone else observed similar behavior? And is there a solution for this?

Thanks!
