Preventive Maintenance; Lubrication And Adhesive Application - Epson DFX-8500 Service Manual

6.1 PREVENTIVE MAINTENANCE

To keep the printer in good condition, regularly clean the case exterior with a soft cloth and some alcohol
and vacuum the mechanism's interior to remove dust and paper debris. After servicing the printer, make
sure it is adequately lubricated, as described in Section 6.2. Before returning the printer to the customer,
make sure the springs and paper feed rollers operate properly.


Unplug the printer before performing maintenance. Do not use thinner, trichloroethylene, or ketone-
based solvents on the plastic components of the printer.
Note: The carriage encoder belt should be cleaned periodically. Clean it when the printer is returned for
service.

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 O2 and G26. These lubricants have been extensively tested and found to comply with the
needs of the printer. See Table 6-1 for information on lubricants O2 and G26. Table 6-2 lists the appropriate
lubricant for each lubrication point. Make sure the parts are clean before applying lubricant. Avoid applying
too much lubricant, this may damage surrounding 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 illustrated in Figures 6-2,
6-3, and 6-4. Avoid adhesive overflow onto related parts.
