Registration issue on L40

Hello everyone,

I am having a strange issue in my 1984 Lithrone 40" press. The issue is that the circumference registration only moves very less from PQC. Are we missing something? We have to losen up the four bolts and move the cylinder backward or forward for even small adjustments.
From PQC, it moves very less and then it stops. The issue is consistent in all units.
I am wondering if we need to losen up any bolts before operating from PQC or adjust some limit switches?

 

please define "VERY LESS?" Im not familiar with a Komori but I would imagine that is close to the same as on Heidelbergs. Your only going to get 4 millimeters from fully forward to fully back.

 

My bad. I get close to 5mm laterally and barely a range of .1 mm circumferentialy.

 

That does not sound right even for a Komori.

 

No, not right at all.
