    FK3 on MX465 web runs out quickly

    This first happened on the unit at 90K, got an FK3 and the web has run out. Has happened three times since about every 22K prints but I actually think the the web is running continuously since there are small areas of toner buildup on the web followed by larger cleared areas.

    Done all of the standard things. Reseated the connector and updated ROM's. There are not any engine switch anomalies that I could find on the 22-6. I have tried different settings on when the web would run at end of job and so forth and there doesn't seem to be change in it's behavior. This is a 4 phase motor that connects directly to the PCU.

    Wondering if anyone has seen this or has a likely suggestion? Nothing on Sharpnet regarding this. We're going to replace the PCU for starters but thought I'd ask.

    Thank you in advance for your time and effort in this matter.

      A 1
      B 200
      C 1

      I changed the value of B from the default of 100 to 200 to see if it would help. No such luck.

          have you checked the voltages in the web motor & cn16 pin 18,19 of pcu pwb ? also put a mark on the web and perform a 43-31 and check how far web moves. your setting should move few mils.

            I have the webm voltage coming from CN10 on the PCU Pins A-1,2,5&6 with webend coming from CN16 Pin A-2. Is there something I'm missing. My info from the TM signal list page.

            Thank you.

            I will give your suggestion a try today when I'm over that way.

                C value is 53 and F value is 40. Not default values but these haven't been changed that I know of.

                Thank you.

                    Had this trouble also on 565 at a County Recorder they did a lot of B/W reverse and found out in service manual that this model actually advances web based on pixel count/ratio rather than a set amount after so many pages..
