The roll-to-free-fall roller should be cleaned whenever it is visibly dirty (for instance, whenever ink has not
cured properly when using the roller), or when you notice that substrate advance is no longer smooth and
regular (for instance, if you notice that the roller often slips when trying to keep the substrate under tension).
Prepare to clean the roll-to-free-fall roller and pinchwheels
1. Check that the printer is not printing.
2. Unload the substrate.
3. Raise the pressure roller lever if it was previously lowered.
Clean the roll-to-free-fall roller
1. Clean the roller with a clean cloth dampened with water (for persistent dirt you may use isopropyl
alcohol, but do not use petroleum-based cleaning liquids).
2. Turn the roller manually and keep cleaning to make sure the rubber surface of the roller is cleaned all
around.
WARNING! Take care not to trap your finger when turning the roller.
3. Ensure that the cleaned parts are completely dry and the vapors have completely evaporated.
