    eStudio 3500C with C580 ... and more!

    The C580 was easily explained, and I didn't like the explanation.

    08-1912 had an unusual value. Usually it's 0 or 1 (1 for the MJ-1101 finisher). This machine was at 255, so I set it to 1. Easy, right? Nope. The next code was C4B0. Don't know that code? I didn't either. It's Fuser Count Abnormality. How abnormal? 33,424,638 copies. And the PM counter was at -16,746,239. That's abnormal.

    The 6S-2 PM values are mirrored in 08 mode. I found the 08 fuser PM values, and reset 24 modes to 0, 3 modes to 350000. Great. I check values in 6S-2. I've managed to zero out the heat roller, and a couple others. The disturbing part is that all the other 6S-2 values read either over* or err.

    The answer becomes clearer when I find 08-257. On the left is displayed the total count on the Logic Board: -16515190. On the right is the total count on the System Board: 214915. Which one do you think is correct? I'm going with the system board. Can you imagine a 3500C with -16M copies? I don't even know how to make negative numbers of copies. Are those Un-Copies?

    Here is where I realize that there are literally thousands of 08 mode values that are out of specs. Even with the print-out from a working machine, it will take hours of data entry to fix all the values. Has anyone else seen this? I am assuming that my Logic Board and possibly the NVRAM are toast. Is it possible to clone the System Board counts back to the Logic Board? Or clone the values from a working 3500C to the dead one? Even if I only had a couple hundred values to change, it would be a major improvement. Comments? =^..^=
    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.

      I made some progress today. First tried the NVRAM LGC. Easiest ... and didn't help. I couldn't even get into 05 mode to start the installation instructions. The C580 code blocked me. Second, I put back the original NVRAM and replaced the finisher interface PWB. C580 becomes C570 (again another logic board error). Third I installed the logic board + finisher interface. Well, all except connector CN332, which doesn't fit. It's a totally different connector. I am absolutely certain that the donor was a 3500C, so why is this connector different? Different boards in different serial number ranges?

      That connector feeds M18 exit motor, M19 registration motor, M10 drum motor, and M7 TBU motor. My machine uses the gray connector. The donor had an ivory connector. I hope the replacement board that I ordered fits. =^..^=

          It turns out that my machine was only masquerading as an eStudio 3500C. In actuality it's a 2500C. Now the board fits. We'll see if I can get it to take firmware. =^..^=

              This post gets scarier and scarier. All I can say is that I'm glad that machine is in your territory and not mine!
              Why does every customer think they're the first one to ever say: "you've been here so much we should get you an office, ha, ha, ha"?

                  It's my third day on this bugger, and it's finally working.

                  I made at least two mistakes:
                  1) Assuming that the machine was a 3500C, just because that is what was on the front cover.
                  2) Assuming that all the finisher I/F boards were the same.

                  Once I got the right Logic board and the right Finisher I/F (for the MJ-1101), the firmware took for the MFP and finisher boards. Then all I was left with was the C4B0 (Fuser Abnormal Count). I started down that long road to reset the NVRAM, and finally realized it just wasn't going to work. There are a number of 08 mode values that just wouldn't be changed.

                  With the new NVRAM, I had better success. 08-257 cloned some of the counter values from the SYS NVRAM to the LGC NVRAM. The baseline values were close enough to get through the NVRAM replacement process.

                  If you come across this situation, 05 modes will error out but 6S-2 and the 08 modes will remain accessible. When you browse through the 08 mode values there are basically only three resulting values 33424638 or -16515190 (for values with 8 digits), or 255 (for values between 0-255). 6S-2 values all show as over* or err* in the chart, and 33424638 or -16515190 at the top of the screen when that line is selected. System NVRAM values remained unaffected, and appear normally on the Total Count print off (assuming the you could print, which you can't). The hint that pointed me in the right direction was 08-257: On the left is displayed the total count on the Logic Board: -16515190. On the right is the total count on the System Board: 214915.

                  You know how usually, early on, you can see a path to complete a call? It might be a long path, but you know what to do. This wasn't one of those calls. =^..^=
