MAINTENANCE

1. Preventive Maintenance

Preventive maintenance for the MX-80 F/T 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.

2. Parts Replacement

(1) General
Owing to the sophisticated nature of the circuitry and mechanisms utilized
in the MX-80 F/T, 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 which is
not covered in this section, the operator should contact the store from
which the MX-80 F/T 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 Fig. 33.)
NOTE: Be sure to replace the print head after it has cooled.
STEP 1. Take off the printer lid and cartridge ribbon.
STEP 2. Turn the head lock lever clockwise and remove the print head.
STEP 3. Pull the head cable out straight while steadying the head connec-
tor on the terminal board.
STEP 4. Put a new head on the carriage assembly and replace the head
lock lever.
STEP 5. Insert the head cable into the head connector carefully.
NOTES: 1. Inadequate connection may cause malfunctioning of the
head.
2. The carriage assembly should not be moved without the print
head mounted on the carriage.
