MAINTENANCE
Proper maintenance is essential to assure optimal printer performance for the longest possible period and to
minimize malfunction frequency.
6.1 PREVENTIVE MAINTENANCE
Preventive maintenance includes regular cleaning of the case exterior using alcohol and occasional vacuum-
ing of the mechanism interior to remove dust and paper particles.
Following cleaning, refer to Section 6.2 to verify that the unit is adequately lubricated. Before returning the
serviced printer to the consumer, inspect the springs, paper-feed rollers, and the basic operation of the unit.
6.2 LUBRICATION AND ADHESIVE APPLICATION
Epson recommends that the printer be lubricated at the points illustrated in Figure 6-2. These lubrication points
are listed in Table 6-2, along with the recommended lubricant for each point, Epson O-2 or G-27, both of which
have been tested extensively and found to comply with the needs of this printer. (Refer to Table 6-1 for detailed
information about O-2, G-19, G-26, and G-27.)
Be sure that the parts to be lubricated are clean before applying lubricant, and avoid excessive application,
which may damage related parts,
Adhesive application is necessary at the point indicated in Table 6-3 when the part is disassembled or replac-
ed. Epson recommends Neji lock #2 (G) adhesive be applied to the point diagramed in Figure 6-1. Avoid overflow
of excess to related parts.
