Every time I use a USB drive to capture a scan the 8740 tells me it does not recognize the file format. My Win 10 PC does. So I turn off the printer (sometimes I pull the plug since it could take 10 minutes to shut down) and then when I insert the USB drive. It is then recognized.
The drive was not in any PC or other device in between. I would use the 'scan to network' feature, but that doesn't work for me. Well, maybe one time out of every 10 attempts.
I like the printer, but I am growing weary of the sac issues.

Hi,
Thanks for using the HP Support Community.
The USB needs to be formated to FAT32.
This example will show you how it's done and Scan to USB:

I placed a previously unused, newly formatted (Fat 32) drive into the printer and the response was 'formatted by a file system that is not supported'. After a 'hard' reboot, the printer recognized the drive. I do hard reboots since it sometimes take 5-10 minutes for the printer turn turn off using the power button.
This is a printer issue, not a USB issue.
What can be done to correct this problem? When I try to set up scan to network folder, the system keeps telling me their is a passwords failure which is impossible since I am the one who entered it and I can see that both are EXACTLY the same.
Do I need a software upgrade or do I need to stop using this expensive printer and buy another brand. Please reply.

I opened credential manager and tried that user name with my previously entered 4 digit password. That does not work. The stored password for HP Connected and HPID is about 1 page long and hard to copy.
Why is this so hard?

I am still waiting for a solution that works. Again, I formatted a drive using FAT 32. As soon as I place it in the printer I get an error message say the file system is not supported. Then, when I place it back in my WIN 10 PC, I get an error message that the drive has errors to be resolved. I get this EVERY TIME I take a drive from the printer to the PC. If I do have the PC scan the drive there is no noticeable difference. When I try to use it in the printer, I get the error message noted above, until I do a hard reboot.
Please help. I recognize this printer is out of warranty, but I need assistance.
