EPSON Stylus Color 600 does not have "EEPROM All Clear" function like other printers. If the
printer does not function well and falls into fatal error condition, replace the main board to see if
the problem is rectified. (Refer to Chapter 4 "Adjustment" when you replace the main board since
some adjustments will be necessary.)

Maintenance error clear operation.
