pan roller setting

[Cdel]

Hi everyone, looking for some assistance. When setting pan roller. I go to where the water bead disappears and the 1/2 turn tighter on both sides. I start with that, but I always have to tighten the drive side at least an extra 1/2 turn, usually a full turn just to keep the water out of the rollers. Any one encounter this. I run a 2021 Heidelberg CX 104. LED INK. any tiny bit of water and the impress scanner does not like it. Thanks for any advice. p.s. readjusted fairly new rollers to Heidelberg specs. everything else seems good. Nice scum line and roller stripes.

As a final check you might try using the scum line on the very gripper of the plate to determine your final pan roller setting. I never pass on an opportunity to check on this ANY time im in a unit with the gate open. Lots of information can be gotten from this scum line if you know what you're looking for. A mentioned the air curtain can be a great help when it come to water control but it can also cause problems if you're not always aware of its status. You might want to check if the correct crown has been ground into the pan roller. Ive seen non symmetrical crown cause problems like you describe. Or in the case of newer presses the "skew" of the pan roller.

On my 106 I've noticed that if we run loto tech pan rollers it more like 3/4 turn past bead and skew set to 7, but now we are using botcher spiral and it 1/2 turn and skew set at 8 because the roller doesn't carry the water like the loto tech's.

if the roller is in good condition, I think you have to check the adjustment screw if the thread pitch is not the same, or there is wear in the bearing, if you have a descriptive video it will be much better to understand the problem

CX 104 is print center 3 correct, maybe your servo motor is not moving.
