Preventive Maintenance; Parts Replacement - Epson FX-80 Operation Manual

4.1 Preventive Maintenance
Preventive maintenance for the FX-80/FX-IOO consists basically of cleaning. The
printer should be cleaned with a soft brush to remove paper dust and particles after
every three months of use. The exterior surface of the printer can be cleaned by
using a mild detergent and water solution.
NOTE:
Do not use hard cloth or volatile solvents such as thinner or alcohol when cleaning
around the print head. Otherwise, printed characters may not be impressed on the
paper or may become dim, or a break may occur in the printed character.
4.2 Parts Replacement
(1) General
Owing to the sophisticated nature of the circuitry and mechanisms utilized in the
printer, operator's troubleshooting is logically obliged to be limited to certain easily
recognizable symptoms and cures.
If a printer malfunction other than the print head unit should occur, the operator
should contact the store from which the printer was purchased.
(2) Print head
In case of a print head trouble or a worn dot wire, replace the print head unit as
described below. (See figure on the next page.)
NOTE:
Be sure to replace the print head after it has cooled.
1. Disconnect the power cord from the AC outlet.
2. Take off the printer lid, printer cover and cartridge ribbon.
3. Turn the head lock lever clockwise and remove the print head.
4. Pull the head cable out straight while steadying the head connector on the terminal
board.
5. Put a new head on the carriage assembly and replace the head lock lever.
