Preventive Maintenance
No preventive maintenance is required other than occasionally vacuuming the printer
mechanism to remove dust and paper debris and regularly cleaning the case exterior with
denatured alcohol. After cleaning the unit, check that it is properly lubricated as described
under
Lubrication,
below. Also inspect the springs and rollers to see that they are operating
properly.
Disconnect the printer from the external AC power source before performing maintenance
Lubrication
Epson recommends that the printer be lubricated at the points shown in Figure 5-2. Table 5-2
lists each lubrication point and its recommended lubricant. All the lubricants have been tested
extensively and found to comply with the requirements of this printer. Table 5-1 describes the
lubricants.
Before applying lubricant, be sure to clean the surface to be lubricated. Do not apply too much
lubricant, or it
may
affect related parts.
