Clean the Carriage Rails
Introduction
Dust and debris can accumulate on the carriage rails, which run along the length of the gantry.
The bearings that run on the rails are equipped with shields that are designed to keep debris from
entering the bearing housing. After a period of time and use, debris can accumulate on the
outside of the bearing shields as the carriage travels along the gantry.
When to do
Inspect and clean the rails and bearings at least once a month. If you notice any dirt or ink on the
gantry rails, or an accumulation of debris on the grey rail bearing shields, clean them
immediately.
Equipment
• Poly-Wipe lint-free cloth or a swab.
IMPORTANT
In the event of an ink spill on the rail, it should be cleaned immediately, before the bearings have
a chance to run over the spill. Slight ink stains that remain on the rail after cleaning are not a
major problem.

Procedure
1.
Open the Maintenance Station drawer to ensure that there is no possible gantry or carriage
movement.
2.
Use a dry lint-free cloth to remove any visible debris that has accumulated next to the bearing
shields. It is only necessary to clean the outside bearing shields. When removing debris, always
wipe away from the shields.
3.
Wipe any debris from the carriage rails. Do this gently so that you do not remove the grease that
lubricates the bearings as they move along the rails.
IMPORTANT
Do not use a solvent such as IPA because this will remove the grease and leave the
rails prone to rusting.
4. Close the Maintenance Station drawer.
