    ES523 jams, E3c0, E5A0, E570



    I ran 25 pages without a jam before starting. Look in the jam log and
    the only code was E3C0. So I pulled the tandem supply feed head and
    cleaned and lubed and scuffed up the shafts and tested. It was jamming
    once every 25 pages. At this point it look as though the paper crashed
    in the duplex diverter gate. The code was E020 fuser exit. I replaced
    the upper roller and web. Checked out the fuser section. It showed wear
    but all the gears were meshed.
    Ran some more and it kept crashing into the gate. With code E5A0, did not
    reach exit sensor and indeed it crashed on the gate. Took the spring off
    the gate then ran 225 without a jam.
    On my way out the door, this guy comes up, puts two pages in the doc
    feeder. It jams out the side exit with a code of E570. And he was not
    doing a duplex job.
    I have cleaned the rollers in the paper path, checked to make sure there
    was even pressure on the fuser output rollers. I think I replaced the
    fuser exit sensor a couple of months ago. The last thing it did was jam
    with a sheet coming out of the side exit about 3". Code E570.
    And that was just after I had run 25 pages.

    I noticed that the side exit has it own drive motor, has anyone replaced
    it for jams? I have checked the sensors with the input test. They work.

    Thanks

      E3C0 is almost always a worn registration sensor or flag. It can be intermittent typically at 2M images). New flag stands 15.25mm from the center of the shaft to the tip of the flag. Jamming occurs when flag is 14.5mm or less.

      E020 has various causes:

      Worn heat roller or dry web can be a cause.

      The exit upper idler rollers will tend to turn to dust after a while due to exposure to heat. The edges start to get jagged at first, then the center core breaks loose from the rim. Typically they're all in pretty bad shape by the time that you notice.

      A broken or dislocated claw can do it.

      I've seen E020s when one of your trays is doublefeeding, leaving two pages overlapped in the fuser. Often it has something to do with special media. Cleaning pickup, feed, sep, and vertical path rollers resolved this one for me, until they ran more of that paper.

      High humidity and the resulting paper curl.

      Broken fuser gears.

      Worn registration flag or defective sensor (hmmmm, where have I seen that before?).

      Inverter sensors and flags (sensors and flags in left door).

      Copying with the lid up, copying books, inadequate lead edge void (should be 3.5mm+).

      E5A0: again lots of causes, many overlapping with E020:

      Exit sensor failure due to heat.

      Cracks and rough areas in the inverter gate (in right door, very hard to see).

      Copying with the lid up, copying books, inadequate lead edge void (should be 3.5mm+).

      Web motor does not run, for whatever reason. In my case a pin had backed out of the connector at last fuser rebuild. The heavy black cake of toner on the web is obvious. It can actually get 90K before the fuser becomes impassable.

      Heat roller.

      Nope never.

      Based on what I've just read, I would order up (none of these are expensive and I've replaced plenty of them):
      registration flag and sensor
      inverter sensors and flags
      exit sensor

      Check:
      upper exit idler wheels
      excessive paper curl
      lead edge void
      inverter gate (disassembly necessary)

      I think that you probably would have identified broken or blunt claws, a web that hadn't been advancing, doublefeeds, or broken or skipping fuser gears.

      Does that help? =^..^=
      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.

          Blackcat,
          I replaced the fuser roller and web on my last call. The web was almost all gone. Still it was not dry.
          The fuser gears are meshed without broken teeth. I did notice an upper skiver missing. I'll order that also.
          And yes that does help very much.

          Thank you very much

          Now I just have to hope I don't have to do my jury duty this week.

              I just re read your post. It is full of great information. It is seldom that I have to check the sensor flags but I have found some with cuts from the paper
              or swollen from heat. Guess I expect to much from these machines.
              I'm sure the customer will appreciate getting their machine fixed.

              Thanks again for the info

                      Blackcat,
                      I'm having trouble locating that inverter gate on the right hand door in the book.
                      Also the exit upper idlers that you spoke of are those the ones on the fuser unit or
                      on the left door? On the left door it looks like the two in the middle are different than
                      the four on the outsides.
                      I am going to stop by and check these items today and if Precision has the parts I will
                      replace as many as I can.

                      Thank for all the help,

                      DR

                          the gate is buried, near the last set of rollers in the outer door. The idlers are on the fuser exit. =^..^=

                              Thanks, I'm about to go over and inspect these items. Precision does have some of the parts.
                              I will get what I can and order the rest.
                              That gate is that the one I took the spring off of? It has a solenoid on the inside of the left door upper corner
                              outside?

                                      Re: ES523 jams, E3c0, E5A0, E570

                                      Blackcat,
                                      Here is my report.

                                      While replacing the sensors in the left exit door, I noticed that the lower sensor flag spring was on the flag but not
                                      in position to make the flag spring back. The flag was just hanging there. I'm guessing the breeze from the fans and
                                      vibrations from the machine were causing it to move in and out of the sensor beam. I also replaced the two middle
                                      idler rollers and moved the out pair in next to the new ones. They did not look as worn. The center had not turned
                                      to powder on any of them. Also replaced all the upper fuser pick off fingers and sanded the lowers enough to smooth
                                      and taper the ends. I was feeling fairly good about finding that spring.
                                      But the customer called in yesterday to let me know it's still jamming.
                                      The only two items that were not in stock was the registration actuator and one of the actuators for the duplex door.
                                      They should be in today and I will replace that registration sensor at that time also.

                                      I'll let you know

                                      Thanks

                                              Well you did have a few different jam codes. The flag in the left door was a good find. Typically that flag will get a 1.5mm deep paper cut, but I've seen the sensor fail also.

                                              The registration flag is an important one, and two of your codes pointed to it. I think you're well on your way.

                                              Do I have a photo? ... yes:

                                              Sorry the photos have flopped, I don't know why it does that.

                                              This is the worn reg flag:

                                              This was my first MacGuyver (semi-successful):

                                              This was my second MacGuyver. That machine went to the graveyard that way years later:

                                              This is the paper cut in the inverter flag:

                                                  Blackcat and Sakivas,
                                                  Thank you very much for the pictures and instructions. Friday I replaced the registration sensor and flag
                                                  Cleaned the registration roller and used compressed air for the lint remover brushes.
                                                  This is a car dealer ship and they typically do not run black copies. But I will check those mylars on that
                                                  exit/duplex guide. I also replaced another flag in the duplex path. I think it was the upper this time. So that
                                                  makes all three sensors and flags have been replaced on the left door. The fuser upper roller, web, fuser exit
                                                  sensor and the middle exit rollers have been replaced. All six upper skivers replaced.
                                                  The oneways in the LCT have been cleaned and lubed, rollers cleaned. They still have a decent amount of tread
                                                  on all. The rollers in the vertical path have been cleaned. The oneways on the transport rollers have been cleaned and lubed.

                                                  The jam codes were E5A0, E570 & E020 were on the first page of the jam log.

                                                  So I ran 100 plus pages different ways including duplex and it ran good. Just like the last couple of times I turned my back
                                                  on it.
                                                  Such is life
                                                  Blackcat, interesting fixes on those actuators. Is that material metal that you bent into shape?
                                                  Thanks for the great help and pictures

                                                          I've done stuff like that with old parts from the Kodaks I used to work on.
                                                          I just get a kick out of it.
