Maintenance
Maintenance 6
Proper maintenance is essential to assure optimal printer performance for the
longest possible period and to minimize malfunction frequency.
Preventive Maintenance
Preventive maintenance includes regular cleaning of the case exterior (using
denatured alcohol), as well as occasional vacuuming of the mechanism’s interior to
remove dust and paper debris.
After cleaning the unit, check that it is adequately lubricated (as described below).
Before returning the printer to the customer, inspect the springs, paper feed
rollers, and basic operation.
WARNING
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.
Lubrication and Adhesive Application
Epson recommends that the printer be lubricated at the points illustrated in
Figure 6-2. Table 6-2 lists each point along with its recommended lubricant. The
three recommended lubricants are Epson O-2, G-20, and G-26, all of which have
been tested extensively and found to comply with the needs of this printer. (Table
6-1 provides product details about these lubricants.)
Before applying lubricant, be sure that the surface to be lubricated is clean. Do
not apply too much lubricant, as this may damage related parts.
The adhesive application indicated in Table 6-3 is necessary following disassembly
or replacement of the timing belt. Epson recommends that Neji lock #2 (G)
adhesive be applied to the point illustrated in Figure 6-1. Avoid overflow to
contiguous parts.
