Officejet pro 8620 fails when scanning to memory stick

[nathani01]

This problem started in the last week apparently after an Windows 10 upgrade. When I select scan to memory stick and insert a memory stick that the computer will read, the HP display window turns blue and briefly displays an error message and then a black and white window appears telling me to reboot the printer. The error code does not remain long enough for me to copy it and appears to change each time I restart the printer. I have been using the printer with Win 10 for a couple years with no problems. Sometimes I see a message saying that the memory stick is read only. I did finally succeed in scanning by unplugging the printer from the computer and using a new memory stickl

Hi,

Thanks for using the HP Forums.

Just a quick check, is the memory stick formatted to FAT32 format?

This resource shows what we're talking about:

Scan to thumbdrive

Also, was there any update to the printer Firmware ?

Thanks.

Thank you for the quick response. I have never needed to format a thumb drive before using the printer so I'm puzzled that I would need to do so now. As I mentioned, I unplugged the printer from the computer and now I find that after reconnecting the two, I can scan to the thumbdrives (I tried several) in all but one case. I did not format any of them. I'm going to accept your solution.

Again, Thanks
