[Error Code] WorkCentre 7435 027-516 code after first scan succesful

[Detonation]

A customer of mine has a 7435. It scans via SMB to a NAS (Synology). The peculiar thing is, the first scan goes well and ends up in the shared folder. But any subsequent scan returns a 027-516 error. Only when the WorkCentre 7435 is rebooted, scanning works again - for just one scan!

Has anyone had a similar problem? I have replaced the SBC and memory. Software version is 75.3.1

I just started experiencing the exact same behavior from a Synology NAS but with a Sharp MX-5071. On the Sharp, the error shown is invalid authentication, check username and password. The scans worked for months before and no usernames or passwords were changed. Similar to your situation, powering the printer on/off allows a scan job to go through but authentication error returns for subsequent jobs. Finding this post makes me think the issue is with the NAS. Did you happen to find the cause of this issue?

Somewhat relieved I'm not the only one with this problem, but unfortunately I was never able to solve this.
