A. Mechanical Adjustment
1. Installing the separation guide of the envelope feeder (Adjusting the gap between the
separation guide and the lower separation roller)
Under normal conditions, the separation guide and the upper cover are to be removed as one
unit. Adjust the gap as follows when you removed the separation guide only for unavoidable
reason or if you need to replace it due to deformation, etc..
Install the separation guide 1.5mm from the lower separation roller. Adjust its position by
inserting the thickness gauges (1mm and 0.5mm) into the gap between the separation guide and
the lower separation roller.
