Use a non-woven cloth to wipe away dirt from the stainless steel guide rail. After cleaning the left side, move the print head to the far left and wipe the right side.
Remove the grease and brush, dip the brush into the grease, and apply it to the stainless steel guide rail.
Click the printer's operation panel to reset the print head, then apply lubricant with a brush along the left side of the guide rail, ensuring complete and even coverage.
Note: Do not allow lubricant to come into contact with components near the guide rail, such as the grating bars.
