On the sp15, the motor unit and ink drum are held under the press bed within a unit mounted on two pivots. Two springs create tension on the unit enabling it to spring back up after the impression cylinder has travelled over it. What I want to know is how ‘springy’ this assembly should be – an adjustable padded bracket on the non-operators side controls the amount of play this unit has: the higher the bracket is fixed, the smaller amount of spring the ink drum has.

Thanks!

John Christopher

    Thank you Paul – I had already assumed that was the case but it was worth checking.
