MAINTENANCE
1. Preventive Maintenance
Preventive maintenance for the MX-80 Type II and MX-80 F/T Type I I (hereafter
referred to as “Type II Printer”) 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 Type II Printer, operator’s troubleshooting is logically obliged to be
limited to certain easily recognizable symptoms and cures. If a Printer mal-
function other than the print head unit should occur the operator should
contact the store from which the Type I I 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 Fig. 69.)
NOTE: Be sure to replace the print head after it has cooled.

lever.
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.
