    HP 4014 condensing image at lead edge

    Went to a call today for this problem on a HP 4014, it is condensing the image, about the first 2" from lead edge and happens about every 5th page or so.

    Has anyone had this problem ?

    Does it look like that across the whole page? We can only see the HP logo portion. I'd first make sure the firmware is updated to the latest version (currently 04.260.1). Are you using genuine toner cartridges? I'd suspect formatter as probable culprit.

      Yes, across the entire page 2" from lead edge, customer is using AM toner but has 4 of these units and this is the only one doing it. I am wondering if it might just be the toner cart

        I've learned my lesson with AM carts. Had a P3015 posting a 13.20 error. Bad fuser or sensor, right? Sure......

        I put another AM cart from another P3015 and it started working fine.

          Thanks for the replies Lance, I'll be back there tomorrow to change that cartridge and find out. I do believe all of there 4014 are using current firmware, I suppose
          a formatter could cause this but I have never seen any HP printer do this and I serviced many of them over the years, it is odd for sure

            Sad to see a good machine go to waste. The generic toner is only gonna cause more issues down the road. Starts with a simple error like Install Cartridge and then you start replacing main gear assembly and maint kits alot more. The issue you are having is the cart is throwing off the timing in the main gear assembly. I have seen carts with too much torque and some with not enough as they have been refilled too many times. Other issue can be the transfer roller assembly. Turn it with your fingers on the edge for a few rotations to see if there is any resistance at all. Doesn't hurt to pull out the assembly and clean the bearings. Check for toner build up under the transfer roller.

            Hope this helps

              Thanks JRtech, I did check the transfer roller and all was fine there. The more I think on this issue, the more I think it is the AM carts the customer is using.
              I will post an update for this after tomorrow's visit

                On Samsung I've seen generic toner AIO cartridges stall the main drive, but you don't get this effect. Since the cartridge and registration drive use the same motor, the image should still register regardless of what speed it runs at, or if it varies.

                OK, I'll take that back. If the drum drive stalls or slows during the exposure cycle while the laser is writing the charge image onto the drum, then the resulting latent image will be compressed. If the drum stalls during the transfer phase (and the drive gears jump) the image will be expanded.

                So yes, generic cartridges as a cause of compressions is logical ... even likely. =^..^=
                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.

                  That is what I'm thinking on this Blackcat, Thanks for your input on this too! This unit also registered a few 13.02
                  jam codes in it's recent history

                    Went back today with a new toner cart (customer had none) and yes, that was the issue
