    BH-423, no sort function

    BH-423, no sort function (No finisher, just the machine)
    This machine came long ago from a wholesaler. The mechanical counter was at 150.00, but the electronic counter 000.000. So obviously something weird with the NVRAM. Those days, we explained to the customer the situation, and he accepted to take the machine as it is.

    However, after 1.5 years he wants to use the sort function, and it worked from time to time, but not always. Now suddenly, strange enough, no sorting anymore at all. The function is visible and highlighted in the display, and it can be chosen, but sorting does not function. Paper and other settings are right. I checked it several times. Reinstalling firmware worked for a few days, but then the problem came back and sorting is not working anymore at all.

    I have a donor machine and could replace the boards with their own NVRAM belonging to it (counter settings are not important, and I have the feeling that the original NVRAM is the culprit). Since it is a very unpleasant job to do, with a clear risk, I would love to avoid replacing the boards. Any ideas for an alternative, please?

      just to be sure i understand, there is no finisher right?
      you can only do criss-cross sort having portrait paper in one tray and landscape in another.
      no offset sort with no finisher.

      you said paper settings were right but you didnt mention orientation.
      We know a thing or two because we've seen a thing or two.
      The medication helps though...

          That's the way I read it. =^..^=
          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.

              -Definitely no finisher
              -1st tray has portrait, 3d tray has landscape
              -Criss-cross sorting is selected
              -It worked before but only occasionally.

              It seems that someone put in this B&W machine a NVRAM of a color machine.
              The control panel display is showing “Color” (Farbe in German) in the first large button and “Schwarz”, (German for black). Comparing with a good functioning B&W machine, the control panel has the first button marked with “Density” and a density scale. See attachments.

              I have a donor machine BH-363. Would it be a good idea to put its NVRAM in the problem machine BH423? Any errors to expect? Customer doesn't care about counter or other stored settings.

                  Yes, for sure, no finisher. It's criss-cross sorting what we want and what the machine was doing before, though not always. Now, suddenly not anymore at all. Strangely too is that display is showing a slightly different menu. Instead of the large button "density" it is showing a button with Color ("Farbe" in German)

                      hey, look at the auto paper selection, if one of the trays is not highlighted it wont see it for the other orientation when sorting.

                          The machine will actually sort paper without a finisher attached, but you have to have the 8 1/2x11 paper in there, in one tray it has to be in the landscape direction, and portrait in the other tray..... My guess is this is your issue/question.

                              Just guessing: Maybe both directions of paper may need to be in the on-board trays, not accessory trays?

                                  That could be an issue. The secretary insists, that when she slams any size of paper on the platen, the machine chooses the 3rd large cassette. That's why they disabled Auto Paper Selection. I tried to use criss-cross sorting on my machine here, and it worked, but...... when auto paper selection was off, it didn't sort. Will go there tomorrow and see.

                                  Still, there is the issue that this B&W machine has a NVRAM from a color machine, judging from the display in the control panel. See my previous post. Don't know if changing the NVRAM is worth the risk that I nuke the machine.......
                                  I have a donor machine BH-363. Would it be a good idea to put its NVRAM in the problem machine BH423? Any errors to expect? Customer doesn't care about counter or other stored settings.

                                      If there is enough of the bizhub363 I would just swap even up, and be done with it. Lowest risk. =^..^=

                                          You mean swapping the machine, or the board with NVRAM Cat?

                                          No, no way, too much work swapping the whole machine. Transportation, stairs up and down, configuring scan addresses and so on.
                                          Will go there tomorrow and see if perhaps the suggestion from Synth will work:

                                              Don't mess with the NVRAM. There is a software switch setting that can be changed to make sure that the copy screen doesn't give the color selection button on a B&W machine.

                                              Go into service mode -> System 2 -> Software Switch Setting. Select Switch No. -> [type in] 71. Hex No. [type in] 02, -> [press] FIX. Exit out. You might want to verify what switch 71 is set for in the 3-series you have that is working correctly and use that number, but I know a HEX of 02 will disable the color selection.

                                                  Hans can you still get DS collars for these machines. Parts are becoming super rare around here no more DV units or DR unit, dev or anything else on the tip of africa left... Sounds like paper setting issue to me. Could be faulty paper size detection from slamming and breaking the holder behind the trays.
                                                  Whatever

                                                      Hi Allan,

                                                      I still have some collars here. BTW we always reuse the old ones.
                                                      They last forever and do not crack like the lousy cheap replicas from KM........ 😎

                                                      How many pieces of the DS-collar would you need, Allan?

                                                      Hans

                                                          I still have some collars here. BTW we always reuse the old ones.
                                                          They last forever and do not crack like the lousy cheap replicas from KM........ 😎

                                                          How many pieces of the DS-collar would you need, Allan?

                                                          No real need now just good to know you have a solution to keep one of my favorite machine types alive and serving someone instead of ending up as e-waste.
                                                          I already successfully 3D printed them and we have almost non left only the ones I sold without SLA for cash to worry about. Got some still running.

                                                          Running cost if done right puts a smile on my face.
                                                          Whatever
