    Anyone else had machines losing scan settings? Ever had a hacked MFP/printer??

    I've had 3 machines in two weeks lose their scan/paper size settings, two different brands, two different customers. It could just be someone in their office pushing buttons or playing with the web interfaces, but I read an article stating that printers and MFP's are being hacked. Anyone else??

      These settings are lost mainly due to short circuits and they don't get hacked automatically unless if someone does it intentionally.

          I have seen a few instances were people's machines were incorrectly connected to their network and the web interface was open to the entire internet, usually becuase of IPP or reusing an IP from a DMZ'ed host and not changing the rules at the switch or the router. For the most part though these are settings that get screwed up through power issues, bad controller batteries, failing boards, and DFU's (Dumb F(cking Users).

              It might be a problem with wall voltage. I don't know about the machines you are working on, but that used to be enough of a problem with older Risos (all sorts of mysterious and stupid things happened then thanks to power surges and such causing bad data in the machine's operating memory) that I told people how to clear the problems. Riso had an easy way to do that without going into tech mode, though.
              Still, if there is construction nearby, or recent storms have affected the power grid, I'd look to those. If you can, get those machines plugged into line conditioners, that will take care of a number of those problems. Or even a decent surge suppressor will help some.

                  On the some of the Kyoceras I came across a few VoyagerE's that after 4 or 5 years a scan-to-SMB destination would become inaccessible. The information showed correct in the web interface. As an experiment I re-entered each line of data. On one machine it was folder path. On another it was login username. When the exact same data was re-entered and submitted it started to work. I'm guessing that the HDD was developing bad sectors, and by re-submitting the data was stored somewhere else. I've also seen it with scan-to-email credentials. =^..^=
                  If you'd like a serious answer to your request:
                  1) demonstrate that you've read the manual
                  2) demonstrate that you made some attempt to fix it.
                  3) if you're going to ask about jams include the jam code.
                  4) if you're going to ask about an error code include the error code.
                  5) You are the person onsite. Only you can make observations.

                      The 4 ways you can hack a copier:

                      1. The copier is internet facing and is using the standard manufacturer username and password.
                      2. Someone internal of the network screwing around.
                      3. Someone has the manufacturer MIB file which will allow you to change anything via SNMP.
                      4. Pissed off Tech.

                      I would have to agree with nearly all the comments above about the power issues, boards failing, HDD's and in general, the machine getting old.

                      All though it never seems like it, always remember that coincidences happen alot.
                      Please don't ask me for firmware or service manuals as refusal often offends.
