How to Clean the Rubber Capstan
Introduction
The capstan is a rubber-coated roller that helps to track and guide the media position. It
has an encoder at one end and a brake at the other. The capstan must be kept clean and
its rubber surface free of blemishes or defects to ensure accurate media transport and op-
timal print quality.
When to do
Any time there is any foreign matter or debris on the capstan it must be removed imme-
diately.
Required tool
• Swiffer Brush (or equivalent dust remover)
• Lint-free absorbent clothes
• Rubber gloves
• Mild detergent
• Lint-free cloth
• Isopropyl alcohol (95% pure)
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.
Attention:
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 dif-
ficult (or impossible) it will be to remove the ink.
