    MX-m6070 lines

    Hello, I have an MX-m6070 that is leaving lines on prints. The type of lines that are caused by lack of charge on the charge corona in certain areas. The lines bounce around from print to print. The full Halftone test prints look like crap, the density is dark and light in different areas. I plugged in a new Main Charge, Drum, cleaning blade - No dice. It's like I'm not getting charge in random parts, so my drum is 'more positive' in random places.
    Also SIM46-74 fails, probably because the gradation is so bad.

    Any ideas?

      Sounds like your process control is out of whack. After clearing 24 drum and MC counts..Have you run 44-2, 44-27, 44-6, 44-26? Then try 46-74.

          Yes I did, all of those completed successfully. Fails at 46-74, first scan from the glass.

              Does it just beep twice or something? that's not terribly uncommon on this devices. Sometimes putting a stack of white sheets behind the original works.

              But it's probably not wise to try 46-74 if the original is already messed up

                  Haven't had this on this particular series but when I have had 46-74 fail on previous series, I try to do a 67-24 first then go back and do the 46-74. Has worked for me when process control is screwed up and nothing else seems to work.

                  Good luck.
