Insert Paper Between Rolls:
Disengage the nip to allow our paper to be inserted. Not much room is needed: 1/8” is sufficient.
After the nip impression paper is nicely centered between the disengaged nip rolls, engage the nip at your standard pressure to make an impression.
Then release & remove the nip impression paper.
Lay nip impression paper on the lower roller, centered, then engage the nip system.
