Hi twollert,

I bought a VersaLink B405 a couple of days ago. The printer turns on (the fan, the display keeps dark) unexpectedly sometimes - without getting a print job or similar. I found out that it happens mostly when a person passes the printer. What could be the reason for that? I already turned off the NFC function. Any ideas? Thanks!
