Figue 2-2.Proper method of lifting a typewriter.
When a typewriter must be lifted or
moved, it should be gripped by its case and
NEVER by the carriage (figure 2-2).
Typewriters should be covered when not
A soft dry cloth should be used to clean
the outside of the typewriter.
Care should be taken to see that erasure
crumbs do not fall inside the mechanism.
Typewriters should be checked daily to see
if they are in good working condition.
Service representatives should be called
when major work is required to fix a typewriter.
On occasion, RPs are called upon to operate
a Mimeograph. It is important that the operating
manual for the model being used be studied prior
to operation of the machine. If possible, the RP
should receive instructions on operating a
Mimeograph from an experienced operator. This
type of machine is extremely delicate and a minor
mistake in operation or adjustment could be
costly. Detailed information on preparing and
cutting stencils is provided by individual
manufacturers in each pack of stencils.
Regular maintenance of a Mimeograph is a
must. The RP should ensure that the following
actions are observed in regard to maintaining this
machine in good operating condition:
The cylinder should be left with the ink pad
side up when the Mimeograph is not in use.
A long-handled brush with soft bristles
should be used to clean lint out of the
Feed rolls should be washed once a week
with clear warm water. A clean damp cloth is
used for this purpose.
Retainer pads and the feed pad can be
removed and reversed when they become worn.
The feed pad should be reversed each time it is
cleaned whether it shows wear or not.
The impression roller should be washed
regularly with a cloth dampened with a solution
of mild soap and warm water. This roller should
NEVER be immersed in water. Other cleaning
fluids should NOT be used as they may damage
The ink pad should be covered with
Mimeograph paper and the backing sheet of a
stencil when the machine is not in use. Excess ink
is absorbed by the paper and the backing sheet
keeps out dust.
A Mimeograph should not be located in
direct sunlight or near a radiator as excess heat
tends to cause ink leakage.
SPIRIT PROCESS DUPLICATOR
OPERATION AND MAINTENANCE
Spirit process duplicator machines are used ex-
tensively throughout the Navy and are normally
referred to as Ditto machines. NOTE: The
word Ditto is actually the trade name of the
spirit process duplicator machine manufactured
by the Bell and Howell Company.
The main advantage of the Ditto machine over
a Mimeograph is its compact size which is ideal
for use aboard small ships. A disadvantage is that
