Dust and debris can accumulate on the gantry rails, which run along the length of the table. 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 gantry travels along the table.
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 rails bearings, clean them immediately.
Poly-Wipe lint-free Cloth or swab
In the event of an ink spill on the rail, it should be cleaned immediately. Slight ink stains that remain on the rail after cleaning are not a major problem.
Because of the possibility of gantry movement it is best to clean the rails with power off.
