6.1 Maintenance
This chapter provides information necessary to keep the printer in optimum condition, as well
as to prevent potential troubles. Cleaning the outer cases consists of wiping off dirt using
denatured or thinned alcohol. It is also essential to vacuum dust and debris accumulated in
the printer when necessary.
Never apply thinner, trichloroethylene, or ketone-based solvents to any plastic
parts. These substances may cause plastic or rubber parts to deform or
degenerate.
Use lubricant or adhesive which are recommended for this printer.
6.1.1 Lubrication and Adhesion
Application of proper lubricant has a substantial effect on the printer condition and durability.
In particular, lubricating at low temperature needs special care. Therefore, be sure to use
lubricants specified based on the experiments conducted by EPSON and technical
information in wide range.
