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 optimal print quality.
When to do
Any time there is any foreign matter or debris on the capstan it must be
removed immediately.
Required tools
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.
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.
How to Remove Solid Debris
Procedure
1.

cloth. Surface may be brushed in any direction.
