Clean the pinchwheels
1. Open the roller latches at both sides and move the roller to the front.
2. Lower the pressure roller lever so that the pinchwheels are accessible.
3. Clean the pinchwheels carefully with a cloth dampened with water (for persistent dirt you may use
isopropyl alcohol, but do not use petroleum-based cleaning liquids).
4. Once the pinchwheels are clean, raise the pressure roller lever.
5. Roll the roller backwards by pushing it (not by grabbing it).
WARNING! Take special care when moving the roller backwards not to hit your fingers against the
black substrate guide behind and under the roller.
6. Once the roller is in position, close the latches at both sides.
7. Ensure that the cleaned parts are completely dry and the vapors have completely evaporated.
