    e2555c CE70

    I have to go visit a e2555c with 158,000 prints that suddenly started reporting CE70 a Drum Drive Switching abnormality.

    The manual says to check a bunch of things but ultimately to replace:

    Drum switching motor (M3)
    Drum switching detection sensor(S11)
    LGC board

    The copier worked on/off all day before popping the Code. The customer would simply cycle the power and get 10-100 prints before the copier coded out again.

    Fortunately, I have a dead e3555c that I can remove the entire assembly from.

    Before I do so, any thoughts?

    Thanks,

      I don't envy you. I just had a brand new out of the box 3515AC with a LOUD noise when first powered on.
      Tracked it down to the gear that couples to the transfer belt. Pulled the drive unit out just to replace it.
      Didn't have one, but it's the same gear on the 35/4555...so I got to pull the drive off of a scrap/parts machine.
      Replaced the drive unit, then it popped a CE40. Transfer belt didn't have any yellow. Pulled the HVT to check/
      reseat the HVT connections, still CE40. Pulled the laser, popped it into a known working 3515AC, bad laser...
      no yellow.
      Fun day!
      BRAND NEW machine.

          I plan to take lots of pictures before I remove the Drive unit out of the original copier. I have never performed this task before.

          As I have the removed part in my hand, I can see there is the opportunity to put the arm in upside down. Six cable connections. I remember now there is a very thin bent metal piece at the bottom of the unit that dropped inside the parts copier that I forgot retrieve and to check what it connects to.

          As the copier performs all other functions A-OK, I do not think the issue is the logic board.

          Really helps to pre-flight this repair in my mind.

              5055c series..Those were of the era of sensors that liked to fail.

              Also could just be toner contamination, those machine can be a little dusty with toner migration depending.
              Not seen this particular error issue on any of mine before.

                  I will start there! Thanks

                      The drum phase sensors were a big problem on the Masherbrum and MashX series, but I've never had to work on them on the Weisshorn. The bad news is that they haven't changed much, excepting the actual sensors. It's basically the same build with minor changes. I can't remember why I had to take it apart, but it looks very similar. I think I had to remove the LED array, and there isn't much left by the time you get the LED array off. =^..^=
                      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.

                          As mentioned above, these old dogs get a lot of toner dust throughout the machine. If you remove the rear panel, you will see the actuator arm and sensor (see below). I have had the actual sensor fail but I mostly see toner/dv covering the actuator arm, causing drag and CE70 codes. I have had one instance as well on a 3505AC.

                              That reminds me! We had a 4555C, finisher/hole punch, LCF, ADF...kept wigging out with a CE-40. Changed sensor even
                              though in test mode it checked ok. Turning it off, copies looked ok.
                              I disconnected the ADF, finisher, LCF and machine worked ok. Checked the 5v...it was 4.9 Connected all the accessories
                              error popped up, reset, brought it back to ready, 5v was 4.78. Replaced the LVPS. Too bad they took the adjustment pots
                              of the power supply. That was a quick fix on the EB2-3 machines with that issue.

                                  I was onsite today. The copier located in an office in a truck repair office had a fair amount of dust inside it. I had not been onsite in more than ten months.

                                  The transfer belt cleaning blade assembly had a lot of waste toner inside it even though the waste toner bag was no more than half full. The spring inside was not deformed.

                                  I cleaned the assembly and put in a new waste toner bag.

                                  I cleaned the entire Developer assembly with compressed air. I took the back off the copier and cleared out a lot of dust.

                                  An internal test print revealed that the image quality was very good.

                                  A check of 03-240 revealed the Drum drive motor worked OK but 03-08 indicated that the Sensor was bad.

                                  Using a very thin flat head screwdriver I was able to pop off the sensor without removing the Drum Drive motor assembly and install another one.

                                  I will wait a few days to see if any call backs occur.

                                                  In the end, I was able to upgrade the customer to a new e2515AC for only +$11.00 more per month than they are paying now (TCO) including a $1,320.00 balance of payments on the old copier.

                                                  I had been back several times with days with 10+ CE70 errors per day. I even left a full time loaner.

                                                  The customer, a busy trucking company, in a somewhat dusty environment, depends on their copier/printer/scanner/ fax/ 12" x 18" paper size printer to work reliably because when they are they are busy, they are really busy.

                                                  Plus, I think the boss wants to keep his Admin staff happy.

                                                  I was beginning to suspect that the gear drive box deep inside the copier, hard to get at with many removals that needed to be first performed, that the lubricant was drying up, causing CE70 error codes. This is a task I was not looking forward to attempting and had never tried before.

                                                  I am now trying to get rid of any copiers in my fleet that are not at e257/eBN or higher by forced upgrade.
