    Greetings,

    When printing in four color we get a double image in the 1st unit and some times the 2nd. We have used various packing and compression pressure adjustments but get the same problem. Also, checked the feeder grippers and feeder board just to rule out everything possible. We also notice that with heavier paper the doubling slightly goes away. Another observation is that it's worse on the right side than the left. What could cause this type of doubling?
    -Attached is an pdf example of the doubling

    Hi,
    I run a spica 429p First thing I would check would be the head stop fingers make sure they are adjusted high enough for the paper or card your running. If they are set to low the feeder is trying to jam the paper under causing miss registering or doubling on unit 1. The same can happen if it is to high on thin paper allowing the the paper head to curl before the gripper grabs it and miss registering the paper. There are four fingers to adjust under the feeder board with a alen wrench. To check slip a sheet of paper that your using under one finger at a time and make sure its not to tight or to loose.

    Good Luck

    I have similar problem with LSX529 I run. Problem I have tends to be related to coverage. If heavy coverage on one 1/2 (drive or operator side) of sheet and little coverage on other half. Have had various mechanics scratch there heads on problem. Reset gripper from feeder to delivery with no change. Komori suggested gripper pads replacement. Another mechanic said could be thrust bearing in a unit. Problem does get better when i put a lot of reducer in all inks and run at least 500 sheets. It is 2015 and is running HUV configuration with UV inks. Hope you have got figured out , as i seen this post is a few months old. Looking at your example, I also am curious if you turned off your cyan unit would it still double on other units? Are you K,C,M,Y or K,M,C,Y? Looks like only C & Y are doubling...... Its frustrating when it happens to me, so I feel for you.
