Section 6. MAINTENANCE
6.1 Introduction
The SP~328 printer is designed
to
require a minimum of maintenance and service. This section provides
instructions for cleaning and maintenance. Electrical and mechanical repairs should be performed by
qualified personnel only. Make certain that all electrical connections are disconnected before any service
is performed on the SP-328.
6.2 Required Tools and Supplies
1.
Common hand tools
2.
Volt-Ohm meter
3.
Denatured alcohol
4.
Cleaning rags
5. Cotton swabs
6. Lubricant IBM #23, LUBRIPLATE #70, SllCON #35
6.3 Cleaning
The SP-328 exterior cabinet may be cleaned with a non-abrasive cleanser. Care should be taken to
prevent liquids from entering inside the mechanical assembly. If in a dirty environment the mechanism
may be cleaned with alcohol and a cotton swab. The mechanism may also be "blown out" with
compressed air. Do not direct air flow directly to the printer platen, this may damage the printing surface
on the platen. When the mechanism is clean and free of dirt a light silicon lubricant may be applied
(sparingly) to the moving mechanical components.
