MAINTENANCE
The purpose of "maintenance" is to maximize the life of your
Gemini. Toward that end, the best maintenance is "preventive."
The Gemini printer is a well-engineered peripheral, and it
serves as a valuable information-handling tool when used
correctly. Part of using Gemini correctly is paying attention to the
operating environment. Chapter 1 outlines the suggested
considerations for keeping that environment clean.
Periodic cleaning of the exterior and interior of your printer
will help keep Gemini going for years. How often you need to clean
depends on how "dirty" the operating environment is.
CLEANING GEMINI
Exterior cleaning: When dust, grease, or other material
accumulates on the outside of your printer, wipe the external
surfaces of the case carefully with a clean cloth moistened with
alcohol.
Note: Exercise the utmost care not to wet the electronic parts and
machine body.
Interior cleaning: Remove dust and dirt from the internal
mechanism by gently using a soft brush. Be very careful not to
damage the electronic parts or wiring circuit.
To clean the interior of Gemini, you should remove the upper
casing, as described below.
REMOVING THE UPPER CASING
Warning: Unplug your Gemini before removing the upper casing.
When you need to set Dip Switch number 1 or change other parts
of the printer, the upper casing must first be removed. Figure 10-1
shows the position of the three screws that hold the upper casing
in place on the Gemini-15X. Figure 10-2 shows the location of the
two screws that do the same for the Gemini 10-X. In both cases,
the mounting screws are Phillips-head types.
