The gap between the two main rolls is called the nip.
The purpose of adjusting the nip is to ensure continu-
ous contact between the main rolls as the media is
drawn through the machine. This procedure must be
done regularly.
Tools required:
•
1
/
8
" hex wrench
• ¾" hex wrench
To adjust the main roll nip:
CAUTION
1. Remove the left and right side cabinet covers with
the

" hex wrench by removing the eight screws
holding each cover in place.
2. Lower the upper main roll so that there is a small
visible gap between it and the lower main roll.

bolt. Adjust the nip by rotating the lift assembly
bolt clockwise to lower the end being adjusted and

Exercise care when cleaning the rolls with 80%
isopropyl alcohol:
•
Use only in a well ventilated area.
•
Wear rubber gloves.
•
Use only on cool rolls.
Cleaning heated rolls can ignite the fumes.
Use only 80% isopropyl alcohol to clean the lower
main roll. Harsh chemicals like toluene, acetone
or MEK destroy the silicone covering of the roll.
Remove and lockout power from the heat press
while you are performing this procedure. You
could be severely shocked, electrocuted, or get
your fingers caught in the drive mechanisms.
Do not use liquid or aerosol cleaners on the heat
press. Do not spill liquid of any kind on the heat
press. You can be severely shocked, electrocuted
or cause a fire. Use only a damp cloth for
cleaning.
Do not use compressed air to clean the machine.
Blowing debris can be forced into places where it
will later ignite or short electric circuits.
The main roll must be at room temperature to
achieve a proper nip setting.
