    Dear valuable members,
    Please can I know what is the usage of dull chrome roller in dampening unit and how can I control the dampening feeding up and down with the adjustment of this roller connecting with dampening from roller?

    Dear Raman,
    I guess you are asking about the dampening distributor roller, if yes.
    You have to adjust the dampening form roller against this roller.
    In SM102 their is a screw directly at the roller journal.
    In SM74, SM52 the screw is under the water pan.

    If im remembering correctly this roller is a fixed roller. That is to say that its NOT adjustable. What is adjustable is the rollers that contact this roller.

    Hi what roller are you talking about because there is the doser that comes on the bubbler and the moistener and the depressor that makes contact with the moistener.

    Dear sir,
    I want to know CD 74 dampening roller setting, because if I adjust the rollers each other, adjustment the screws clockwise or anti clock wise for increasing pressure?

    Dear Raman
    Turning the screw clockwise increases the pressure between rollers, and vice versa.
    And as Mr.Beguin mentioned it would be better to send a photo of what you need to adjust.
