Lotem 800 v image related error

[PACH]

Kala
To me it looks like a Spiral Punch adjustment. If I am correct the Spiral hole has to be smaller in the OLD Lotem and bigger in the new one. There is procedure to do this but you can have a go doing a manual adjustment (trial and error). Yuo have to disconect the molex conector of the punch that drives the motor IN/OUT, and move the WHEEL by hand i.e. 2 turns in one direction (remember this). Load a plate from Loading system to the B satge. Take the plate off and compare the plate for the depth of the hole with a previously used plate. If you see a small difference, expose one separation and measure your grip and see the diffrence. If the error has increased then move the wheel in the other direction..I assume that you are exposing all the jobs at one resolution only so the spiral punch has not got to move. Have a go.

Regarding Gripper Difference , tried increasing X in drum final from -12 to -14 ; nothing happened tried increase y in drum from 12 to 14 nothing happened.....

Planned to change the suckers ; Finally will do the spiral punch adjustment as advised by patch....

Is there is any option to disable the punch and check that gripper will be ok or not, if yes then how we will disable the punch thro registry or under hardware tree...

Kindly advise

Once you are happy with the depth of the Spiral punh hole, as I said before just remove the molex connector that drives the horizontal movement of the punch. Like this the punch will stay in one position. You will always need the Spiral punch hole on the plate .
There is a procedure for adjusting the Spiral Punch.

Kala,
Make sure that all the black small rollers that the plate is moved over rotate freely. Could be plate dust deposit inside these rollers. You can remove all these rollers from the side of the Lotem,RHS if I remember well.A long time ago there was a change of these hard rollers to softer ones. YOu take all the rollers off and clean well the shaft that they are on and inside of the rollers. Have a go. Another place that the plate can get scrathed is the "plate leader" assy that is under the drum. This assy can also be removed to clean the black rollers.
