It may be difficult to tell whether or not all the ink has left the surface. Continue to wet and wipe the capstan surface until the cloth does not show any sign of ink color.
If the scrubbing action leaves fibers from the cloth on the surface, wait for the surface to dry completely, then follow the procedure listed above for Removing Solid Debris.
When the capstan is kept clean and its rubber surface free of blemishes or defects you will be ensured of accurate media transport and optimal print quality. If its surface is badly damaged the capstan will need to be replaced.
