MAINTENANCE

1. Preventive Maintenance

Preventive maintenance for the MX-82 and MX-82 F/T consist basically of clean-
ing. The Printer should be cleaned with a soft brush to remove paper dust and parti-
cles 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

MX-82, MX-82 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, the operator should contact the store from
which the printer was purchased.

In case of a print head trouble or a worn dot wire, replace the print head unit as
described below. (See Fig. 69)
