Proper maintenance is essential to maintain optimal printer performance for the longest possibly period and to minimize malfunction frequency.

Preventive maintenance includes regular cleaning of the case exterior, usingneutral detergent, and occasional vacuuming 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 theconsumer, inspect the springs, paper feed rollers, and the basic operation of the unit.

Disconnect the printer from the power supply before performing maintenance. Do not use thinner, trichloroethylene, or ketone-based solvents on the plastic components of the printer.

6.2 LUBRICATION AND ADHESIVE APPLICATION

EPSON recommends that the points illustrated in Figures 6-2, 6-3 and 6-4 be lubricated, with EPSON 02 and G26, which have been extensively tested and found to comply with needs of this printer. (Refer to Table 6-1 for details of 02 and G26.)

Table 6-2 indicated the lubricant for each points.

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 replaced. EPSON recommends Neji Lock #2(G) adhesive be applied to the point diagramed in Figures 6-2, 6-3 and 6-4. Avoid overflow of excess to related parts.
