Rollem Auto 4

Bought a rollem auto 4 to replace my socbox micromatic
Anyone know how to turn down the p.e.cell so when I number carbonless it doesn't move a 1/8" up and down. Awesome machine for perfing and scoring right now but I need to be able to number carbonless accurately


I have since talked to a rollem rep who has told me the proper way to use this machine to ensure accuracy also there is a little yellow knob on the one control board you can turn to dim the light or brighten it.
