The capstan is a rubber-coated roller that helps to track and guide the media position. The capstan must be kept clean and its rubber surface free of blemishes or defects to ensure accurate media transport and optimal print quality.
Any time there is any foreign matter or debris on the capstan it must be removed immediately.
Gloves (for example: Ansell Microflex 93-260)
Swiffer Brush (or equivalent dust remover)
Mild detergent
Isopropyl alcohol - IPA (>=98%)
Absorbant cloths
Cloth-Poly Wipe 10cm x 10cm (lint-free)
IMPORTANT
The only way to remove cured ink is if the area can be scraped without causing damage (therefore do not allow ink to dry on the platen or the capstan! Partly cured ink can be removed with alcohol. Make sure that any spilled ink is removed immediately before it has a chance to cure due to exposure to light. The longer it is left exposed, the more difficult (or impossible) it will be to remove the ink.
NOTE
Always wear safety glasses with side shields and nitrile gloves when working with ink or liquid solvents. If a significant amount of ink has spilled, consider donning an apron or smock.
Remove lint, dust, paper particles and debris
