Lubricating the two Main Rails will prevent oxidation (rust) and debris
build-up, allowing the Printer Assembly to travel freely. This will help
prevent registration issues that can occur in multiple pass prints.
To correctly lubricate the Main Rails, apply a very THIN coat of the 2.
same Lithium-based grease used for the Rail Guides. Spread the White
Grease along the ENTIRE length of both Rails using a clean, lint-free
cloth. DO NOT use any other lubricate, such as WD-40 or Machine Oil,
or you risk contamination of the Rail Guides.
Do Not Lubricate the Drive Screw
The Drive Screw MUST NEVER be lubricated or wiped
off with a chemical solvent. This is due to a special
coating that has already been placed on the Drive
Screw to prevent dust buildup that could potentially
hindertheuidmovementofthePrinterAssembly.
Treating the Drive Screw will allow dust buildup,
contaminating the drive mechanism.
