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

Owing to the sophisticated nature of the circuitry and mechanisms utilized in the
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)
NOTE: Be sure to replace the print head after it has cooled.
STEP 1. Turn the power off.
2. Take off the printer lid 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.

NOTES: 1. Inadequate connection may cause malfunctioning of the
