MAINTENANCE 6
Proper maintenance is essential to assuring optimal and long-term printer performance and to minimizing
malfunction frequency.
6.1 PREVENTIVE MAINTENANCE
Clean the case exterior regularly with alcohol. Occasionally vacuum clean the mechanism’s interior to remove
accumulated dust and paper particles. After cleaning the unit, check that it is adequately lubricated (refer
to Section 6.2) immediately below. Before returning the printer to the customer, inspect the springs, paper-
feed rollers, and the basic operation of the unit.
WARNING
Be sure to disconnect the printer from the power supply before maintenance. Do not apply thinner,
trichloroethylene, or ketone-based solvents to any of the printer’s plastic components.
6.2 LUBRICATION AND ADHESIVE APPLICATION
Epson recommends lubrication at the points illustrated in Figure 6-3. Table 6-2 provides a list of these points,
and the recommended lubricant to use for each. The lubricants - EPSON O-2, EPSON G-20, EPSON G-26,
and EPSON G-37 -
have all been thoroughly tested and fully meet the needs of this printer. (Table 6-1
lists details of these lubricants.) Before applying any lubricant, make sure that the part to be lubricated is
clean. Do not apply excess lubrication, as this could potentially cause damage.
Following its disassembly or replacement, adhesive must be applied to the part indicated in Table 6-3. Ep-
son recommends application of Neji lock #2 (G) adhesive to the point illustrated in Figure 6-1. When applying
the adhesive, be careful that no excess overflows onto nearby parts.
