    Hi
    I have just installed a Komori L 428 and seem to have an issue when I print lower GSM papers like 70 and 90 .
    The color registration does not seem to be a problem while printing heavier stocks .
    The color registers on one side ( operators side ) while the Colors don’t seem to register from the middle of the sheet to (Motor side )
    Can some one here let me know what could be the problem .
    Will appreciate any help
    Thanks

    Please clean the gripper tips and pads and reset the grippers.

    I have uploaded the left and right registration marks , although the right side of the paper registers almost perfectly the opposite side is clearly out of register .
    The gripper yo tail does not have much of a problem it is the expansion of unit 1 ( black) to the sides that is a problem .
    Can any one help ?

    Wrong grain paper? Grain should run across the sheet from side to side not front to back.

    one option would be getting through impression your paper stock before print
