Preventive Maintenance - Epson LQ-670 Service Manual

6.1 Preventive Maintenance

Preventive Maintenance is important to keep the printer in the best condition and to prevent troubles in
advance. Use the denatured alcohol to clean the exterior case and use the vacuum cleaner if necessary,
to remove dust and paper debris in the printer inside.
; Do not use thinner, trichloroethylene, or ketone-based solvents on the plastic components of the
printer.
; Never use the oil and the grease other than those specified in this manual, and using different type
of lubrication can damage the printer and the components.
; Disconnect the printer from the AC socket before performing maintenance.
The influence that grease and oil give is great and especially in low temperature. Therefore, EPSON has
been tested and analyzed various grease and oil extensively and chooses the best one for that printer.
