    AK-7110

    Has anyone noticed the AK-7110 is sometimes difficult to set into position on the new 4 series machines? Occasionally they seem to hit the exit section. There was never a problem on the 3 series.

    I don't know if it is related but I've also noticed 500x jams on the 4 series machines. Bridge sensor 2 non arrival jam with the paper partway in the AK-7110.

    If anyone has noticed either problem or found a solution I'm interested.

    Take the five screws out holding the ak kit in and while its still in the machine give it a bit of a thump in this area
    Should get rid of the 500x jams

      Re: AK-7110

      Greetings! Thank you for posting this issue. We have 3 devices now that are having the same J500x codes with AK-7110, even on XX53ci units. P
      aper stops partway into the AK. We have replaced the Exit Unit Assembly on one device,and it is still working.
      We ordered one more Exit Unit to try on another device. If that works, I will let you know. Conversely, if you come up with anything, please reply.

        Re: AK-7110

        Good day! I replaced the Exit Unit,but no change. I swapped the AK-7110 with a new one. Checked the connections. Ran switch and motor tests in Maintenance Modes.No change.I had another tech working on the same issue on another Kyocera 5053ci replace the Feed Image PWB,Engine PWB,still jamming in AK. I am trying to avoid ordering PWB's,but I might have to. Updated firmware.The paper just stops.Jam indication shows J5004.Tried different paper sources.Checked paper settings.Any thoughts or suggestions?

          Call Kyocera or your regional field representative. I probably should have done so but my problems have been inconsistent

              Any solution to this jamming problem? We have a 3253ci with j5001, j5009 consistent jams. Both bridge sensors check ok in MM031. Bridge motor runs in maintenance mode. Paper stalls partway into AK-7110

                Re: AK-7110

                Good day! My tech partners and I habe not found any pattern to this issue. I have replaced a AK Unit. We have replaced the right conveying door. I got one going with reseating YC- 25 & YC 30 on the Feed Image PWB. The only suggestions I got from TS is Conveying Motor on the AK. All those listed got the MFP working, but I can't put a finger on it. Try also disengaging the DF from the connector brace that mounts to the copier. Also unplg the connector there. I don't have a definite answer, but will keep track of what I have done so as to provide any further info.

                  OK, I've finally been bitten by this stupid J500x bug, on a new-ish 6003 with DF7110 and mailbox unit.

                  It will sometimes go away with a total power reset(unplug power cord), but returns later in the day and can take the device down. I have found that with the device refusing to work, asking it to perform any finishing function will allow it to work until a job comes that doesn't need HP or staple. sending to tray A or B seems to be unimportant, using a new fuser seems to be ineffective. disassembling/re-assembling the AK7110 mechanical parts in it's motor area seemed to be ineffective.

                  Firmware update has been performed, as has 906 reset. I've checked all plugs on all the PWB's in the back of the machine, as well tightened all PWB screws. the LVPWB has the better 450V bulk storage capacitor on it, which is nice to see compared to the problematic lesser voltage cap that can cause strange issues in other models.

                  I can't understand why using finisher functions can allow the job to complete flawlessly, and then get J500x on subsequent jobs!

                  Is there any QA or other knowledge regarding how to approach this stupid problem? Our branch continues to suffer from no access to QA database... KYO struggles to solve that for us.

                  Best regards,

                    There are not any QA's regarding this issue.

                    You can check your BR sensor signals going into the Feed Image PWB during operation, it may yield some info. Perhaps the connection is twitchy with operation.

                    No one has posted relative volumes at which this occurs but that might point out any wear issues.

                      Re: AK-7110

                      i wish i had a storage scope with which to observe sensor outputs... there is a relay pcb inside the AK, I haven't checked into whether the sensor data is relayed directly through a dedicated pair, or sent in a mux toward the feed image pwb...

                      My current theory is that the sensor 1 (49xx) might be bouncing as the paper arrives, and then upsetting the sensor 2 logic by registering an arrival and premature departure, but has no logical way to handle a "bounce". I'll get a chance to look at the sensor springs/flags/replace the AK7110 next monday...

                      THOSE SENSORS are not easily accessible... I destroyed an old AK7100 exploring how to access them: turns out it's better to go in from the bottom by removing the floor/door than to try to open the top!

                        Re: AK-7110

                        You can run MM030 and then go back and watch the sensors activate as it's running. Set it for 50 pages and see if it jams.
                        Hope that helps !

                          Re: AK-7110

                          when it's upset, it won't print any pages and jams right away first sheet stops in the AK. I tried watching the sensors in maintenance and the second bridge sensor shows as triggered after it stops. the paper does stop just at the sensor which makes no sense why it should think that it hasn't arrived.
                          I received my new AK7110 today, and will swap it out. that better work......

                            Re: AK-7110

                            New AK-7110 installed. Nervous feelings... first page out had jam 5004 then no more. first page of 11x17 also jammed 5002 with the sheet WELL short of the second conveying sensor both times.

                            I noticed that when studying the AK's, there's BARELY any pressure being applied to the first set of conveying pinch-rollers, then slightly better pressure(pre-load) on the remaining 3 sets of pinch rollers along the path. Even when fully closed and tight against the top frame, the first set of spring-loaded rollers barely move whatsoever, and then the lower half rests a little lower than that with the door fully closed.

                            I ended up applying a long mylar "shim" on the right hand side AK closing ramp towards to top of it so that it lifts the lower half just a little and it meets the top frame a bit better. It might not be enough, it might be just what is needed. I'd prefer KYO had better load on that roller set, or that they let us use the AK7100 instead, since it's basically the same, just with less problems.

                              Can anyone verify if these jams have occurred on a machine without a speed license? Just an idea that these are jams created by speeding up these machines.
