    SMB v2 problems

    The latest security upgrade for windows 10 defaults to SMB v2.. This has caused problems with a few of the printers out there. What is an easy fix?

      Unfortunately the solution is to set smb v2 / v3 on mfp, if available, or set scan to ftp

          SMBv2 should not affect your printers, as all printers are on IP or usb connections, and do not scan. So if you are having issues printing to your printers it may be something else such as virus protection added to your PC.

                      Try this : Go into the Windows Apps and Features section to ' turn features on / off ' . Scroll down to SMB and turn SMB1 back on .

                      God grant me the serenity to accept stupid people , the courage to not waste my time and energy on them , and the wisdom to know that I cannot fix STUPID .

                          That's really not a good idea. SMB v1 is a security flaw that Micro$oft closed for a reason. Reopening that hole could open YOU or your company up to a lawsuit if the customer suffers a data breach from it.

                          If worse comes to worse, configure FTP scan, or scan to email for the customer.

                              Thank You Sir, All these folks giving advise to re enable SMB1 are NOT giving good advise and like you said... " Reopening that hole could open YOU or your company up to a lawsuit if the customer suffers a data breach from it. "
                              I have been pressing this response since the problem arose. SOME just don't get it...
