6.1 PREVENTIVE MAINTENANCE

To keep the printer in good condition, regularly clean the case exterior (using denatured alcohol)
and vacuum the mechanism's interior to remove dust and paper debris. After cleaning the printer,
check that it is adequately lubricated, as described in Section 6.2, below. Before returning the
printer to the customer, inspect the springs and paper feed rollers and check that the printer
operates properly.
Disconnect the printer)?om the external AC power source before performing maintenance. Do
not use thinner, trichloroethylene, or ketone-based solvents on the plastic components of the
printer.
Note: It is necessa~ to clean the carriage encoder belt periodically. When this printer is
returned for service, clean the surface of carriage encoder belt.

6.2 LUBRICATION AND ADHESIVE APPLICATION

EPSON recommends that the printer be lubricated at the points illustrated in Figures 6-2,6-3, and
6-4 using EPSON lubricants 02 and G26. These lubricants have been extensively tested and found
to comply with needs of the printer. Refer to Table 6-1 for information on lubricants 02 and G26.
Table 6-2 lists the appropriate lubricant for each point. Make sure the parts to be lubricated are
clean before applying lubricant. Also avoid applying too much lubricant because it may damage
related parts.
Adhesive application is necessary at the points indicated in Table 6-3 when parts are disassembled
or replaced. EPSON recommends Neji Lock #2 (G) adhesive be applied to the points indicated in
Figures 6-2,6-3, and 6-4. Avoid allowing excess adhesive to overflow onto related parts.
