  3. Reach underneath to the right UV lamp assembly and wipe pixie dust using a lint free cloth moistened with isopropyl alcohol.

 NOTE: Always wear nitrile gloves and either a protective sleeve or lab coat when performing this procedure to protect skin from exposure to uncured materials.

​ NOTE: When wiping the right UV assembly use care not to touch printhead.

 NOTE: It may be helpful to shine a flashlight where you are wiping for better visibility.
