loosened ink deposits from the platen.
NOTE Isopropyl alcohol is not provided in the Maintenance Kit.

directly because you will leave too much moisture behind.
7. Clean the cutter ramp with the damp cloth.
8. Clean the exposed part of the wheels with a dry cloth. Ideally you should clean the whole
