    Kyocera 6052ci 7620 7611 7614 7613

    I checked the logs went to the machine for a different fault and came back with lots of 7620 7611 7614 7613 etc which is to do with belt registration. Visually quality is spot on doing a 464 and 410 performs fine no errors. The log seems to indicate it does it once a week at random times then is perfectly fine for another week. I couldnt get it to error out while I was there but it does do it from what I can see every week at random times.

    One thing I never checked was the cam mechanism on the belt the id sensor shutter was working fine I gave it a clean for good measure.

    The machine has done 180k 80k colour 100k black.

    Anything else I should check or should I just order a belt for the heck of it?

    Cheers,
    Fishy

      I would try reseating all the connectors on the paper feed image board, then try the transfer board. those errors other then 7620 are density codes on the transfer belt for the color .7620 is only an internal code it never shows on the screen and only shows after happening 10x

          could it be early signs of a waste blockage?

              Fishy:
              It sounds like you've covered your bases. I would have put the highest likelihood on a dirty patch sensor or malfunctioning patch sensor shutter. What do these images print like? (see attached PDF):

              Since all of the color patches CMYK are erroring out, I think that you can rule out drums, developing units, MC units. A single consumable would cause only errors for that single color.

              Possibilities ... might be the laser (patch images intermittently not written), primary transfer belt (drive issues or belt cleaning), or maybe a bad patch sensor. I haven't seen any of these conditions on this model, by the way. If possible it would be nice to see the last few prints just before the error.

              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.

                  Yeah I thought that was expecting a piece of paper to be sticking out the belt or for the belt to be blocked up.

                  I'll print them charts out if I have to go back. Is there a way to check the id sensors are working?

                  I'll just have to see if they report the colours going funny. Just a crazy one with it being intermittent.

                      Funny! I was just having a thought, and your report confirms it.

                      Maybe completely unrelated ... but I've been working on a bizhub 658e that every day when the enduser shows up for work, the display reads "Self-Diagnosing ... ", which can be cleared by power cycling the machine. The interesting thing is that the Detail Report show that each "event" occurs around 0645 each morning.

                      I set up the power quality analyzer on Monday, picked up the data on Wednesday. When I compare the Detail Report to the PQA, I find that at the exact minute of the "event" there is a nasty sag of 8.0vac Hot to neutral, and a nasty spike of 2.8vac ground to neutral. The confirmation for me is that the machine is ASLEEP, and noone is in the office at the time of each event.

                      Personally, I believe that the power company is making some sort of load adjustment, each morning.

                      Look at the screen shots:

                          That sounds like a nightmare how do you explain that to customer if it's only affecting the printer?

                          So basically ruling stuff out here by order of difficulty..

                          ID sensors
                          ITB
                          Laser unit
                          High voltage - Transfer Bias
                          High voltage - Dev Bias (very unlikely with it being intermittent)
                          Engine board (very unlikely)

                          Seems to be all colours so had to something that effects them all. Is it worth doing a U140 and a U412 just to reset Dev biases?

                              It helps that the customer already knows about other power issues, and it's an old building. AND they've got this same message on at least 5 different printers in the same building, sometimes two affected at the same time. Since it's mainly one device that dislikes the power hiccough the most, and it's a really long way to the power box, I recommended a power conditioning device 1800watt capacity. It's not cheap, but cheaper than an electrician to run miles of wire.

                              Did you notice that most of your errors occurred within a 10 minute window? How likely is it that the machine is having an issue at exactly the same time each day ... or there is something else external the machine causing it? We had another Toshiba experiencing print data errors at a very specific time of the day each day. It turned out that the cameras were downloading image data to the server at that specific time of the day, causing this error.

                              ...
                              That sounds like a good plan to me. Lowest cost and highest likelihood first.

                              It certainly won't do any harm, but these values are reset at each self calibration, so I can't imaging that to be any sort of long term solution.

                                  How do you check a solonoid or motor with the door open? If you interlock the door via the switch at the top just comes up paper jam. It looks like the sensor at tray 1 needs the door to be shut.

                                          I wanted to visually see the id sensor shutter open and close.

                                              I don't think there's any way to view that. Door Open will prevent running the service mode. And it will error out without the transfer belt EEPROM. You can only listen for the "click".

                                              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.

                                                  Aww shame they don't let you run test routines with door open.

                                                      We created door switch set by 3D printer
                                                      See enclosed picture for all 4 locations.
                                                      Optical sensor for switch 2 is located on the left side behind the "A1".(It was easier to block "A1" by using the right position)

                                                          I think blackcat was on the right path with his first post. I think you can rule out the drums and developers. You can rule out the ID sensors. Basically that leaves you with the a drive issue, transfer belt or a possible laser problem.


                                                          What's the count on the transfer belt?

                                                          Also, I agree with KYO. You need to look at values of U465/Stress.
