HOW TO USE
CoronA
The Personal Writing Machine
Introductory
In preparing this book the
manufacturers of Corona
have endeavored to explain
the operation and care of
their machine in the simplest
manner possible. It is in-
tended that the book be kept
on hand for future reference.
While possessing all the labor-saving devices of the modern
correspondence typewriter, Corona is extremely simple in construc-
tion and operation, there being only 692 parts as opposed to 2,000
or 3,000 in the ordinary machine. However, the operator should
not gain the impression that, because of its simplicity, it is not liable
to derangement, if mistreated or neglected.
Even though you are an experienced operator, read this book
carefully. As you know, there are lots of ways of doing athing
—
but only one right way.
Unpacking and Putting in Condition for Use
Remove case from box or carton and place flat on table with
cover side up. (Handle is attached to cover.) Release catch by
pressing button upward, open case and remove packing.
Unfold typewriter by grasping carriage at both ends and lifting
it back to its position on the frame. Now release Shift Lock (See
Page 8) by pressing toward you. To positively insure the escape-
ment from damage during transportation, Coronas are shipped
1

from the factory with the Carriage Release Lever tied to the
Platen Knob. Remove this cord, depress the Back Space Key in
order to release the escapement throwout, press back Paper Release
Lever and the machine is ready to operate.
Under ordinary conditions the machine is taken out of the case
to be used, but it may be operated without removing from case, the
lid being attached by "slip hinges" which permit removal, if desired.
Setting Paper Fingers
The Paper Fingers may be moved to the right or left by merely
sliding. There is enough spring in them to permit of lifting when
it is necessary to move them with paper in the machine.
It will be found that the easiest way to move the Paper Fingers,
is to extend the carriage until the finger to be moved is well exposed
and then slide it by pressing against the lower portion. It is advis-
able to set fingers to width of paper before inserting letter.
Inserting Paper
Slip paper between Platen and Paper Table, and while holding
down firmly, give the Platen Knob atwirl.
In order to facilitate the inserting of all paper in exactly the
same position, apaper guide is provided on the Margin Release
Lever. By pressing this lever toward you with left hand, it is
brought into aposition where it acts as aguide for the left edge of
the paper. Thus uniform margins on amanuscript or long letter
may be maintained without resetting the margin stop.

How to Use Corona
When it is necessary to make corrections in aletter, which has
been removed from the machine, the space to be filled in can
quickly be located by means of the scale on the Line Indicator.
Thus :bring bottom of printed letters on aline with top of scaled
wings. First press Paper Release toward you until it catches.
Then locate any letter so that one of the white marks on the Line
Indicator will come in the center of that letter. Now throw back
Paper Release Lever so that paper will be held securely in position
selected and move carriage until the space to be filled in comes
opposite opening in Type Guide.
If any difficulty is encountered in locating the exact writing
line, raise the Platen Release Lever, thus freeing the Platen so that
it may be turned to any position desired.
When anumber of carbon copies are to be made it is advisable
to lock Paper Release while inserting.
Straightening or Adjusting Paper
Insert paper as described and feed through until several inches
appear above the top of
Paper Fingers. Then
bring remainder of
sheet forward until it
touches portion you
have fed through. Now
press Paper Release for-
ward until it catches, in
order to free paper
enough to permit of
swinging it to left or
right until corners of
fed portion coincide
with edges of the por-
tion held in hand.
(See illustration.)

How to Use Corona
Use of Margin Stops
LINE SPACE LEVER
INE SPACE
ADJUSTER
Corona is equipped with aright and left adjustable margin
stop. In order to fix the margins at any predetermined points on
the scale, tilt carriage forward until numbers on Back Rod can be
plainly seen. Then press on knurled portion of amargin stop and
slide to number corresponding with that selected on front scale.

How to Use Corona
The left edge of Margin Stop should be fixed on the number
desired. For example: if you wish to fix the left margin at the
point 20 on the scale, set left adjustable stop with its left edge
on 20.
When the Right Margin Stop is set on agiven number, for
example 60, the carriage will lock on 61, after printing on 60.
Should it be necessary to write afew more letters to complete a
word which cannot be divided, touch the Line Lock Release Lever
and the carriage will proceed to the end of scale, if Paper Finger
is not set in too far.
Line Lock
Another feature of Corona is the positive Line Lock. By
means of this simple device the type bars are automatically locked
when the end of aline is reached;—thus preventing the very annoy-
ing piling of letters at the end of aline. As awarning that you
are approaching the end of aline the bell rings eight spaces before
the carriage stops—after which, upon pressing the Line Lock
Release Lever the carriage will proceed to the end of the scale as
previously explained.
Writing on Ruled Lines
The Platen Release is at the left end of the carriage. When it
is desired to write on ruled lines, fill in blanks, etc., raise this
release. The Platen may then be turned freely without regard to
regular spacing. (See Inserting Paper.)
Spacing Between Lines
To space between lines, press back the Line Space Lever with
thumb, as far as it will go. Time will be saved if this operation is
performed simultaneously with the return of carriage to the head
of anew line.
Distance between lines is regulated by means of the Line Space
Adjuster. Turn the Adjuster back for double space and forward
for single space.
For irregular spacing see "Writing on Ruled Lines/'

Paper Table Extension Arms
These arms may be swung up so as to form an extension to the
paper table. They are particularly useful when machine is being
operated in aconfined space or a"book" of carbons is being made.
Operation of Shift Keys
The Shift Keys are the two large black keys marked "Fig" and
"Cap."
To write acapital letter—hold down the key marked "Cap,"
at the same time striking the desired letter.
To write a numeral or any one of the characters shown on
upper portion of keys—hold down the key marked "Fig."
If it is desired to write aline of capital letters the capital shift
key may be locked in position by holding it down and pressing
back the Shift Lock.
The figure shift key may be locked in the same manner.
To release the lock, press forward.
Starting aNew Line
Push the carriage to the right as far as it will go, at the same
time operating the Line Space Lever, as described under "Spacing
Between Lines." Back Spacing
When, for any reason, it is desired to move the carriage back
to the right one or two spaces, the Back Space Key should be used.
This key will move the carriage one space at atime. It should
be allowed to spring back to its normal position before being
depressed asecond time.
Carriage Release
The Carriage Release permits the carriage to move to the left.
It may be operated from either end of the carriage. Press it
forward. Operation of Two-Color Device
Printing in either of two colors is regulated by means of the
Ribbon Indicator. This indicator has two positions on the colored
dial.

How to Use Corona
1. To print with upper portion of ribbon, shift indicator to
left. (Black.)
2. To print with lower portion of ribbon, shift indicator to
right. (Red.)
Cutting aStencil
Corona has clean, sharp type and apowerful stroke. It is
therefore an excellent machine for cutting the stencils used on
rotary duplicating machines.
To cut astencil :First wash the type thoroughly as directed
under "Cleaning." Then slip the ribbon out of the slots in ribbon
vibrator. Loosen nuts on both ribbon spools, allowing ribbon to
hang suspended between the two spools. The spools need not be
removed.
Reversing Ribbon
When one spool is nearly full the ribbon should be reversed.
This is done by loosening the Ribbon Spool Nut on top of the full
spool and tightening the nut on the empty one. Particular atten-
tion is called to the fact that one spool must always be loose, other-
wise the ribbon will be pulled in both directions at once and the
machine will refuse to operate.
Writing on Cards or Labels
It will be noticed that both the Paper Fingers and the Margin
Stops on Corona may be moved close together.
For card writing, it is advisable
to move the Paper Fingers so that
they rest on the edges of the card.
\The same applies to large labels,
Ibut for small labels and stiff
|cards our label holding attachment
should be employed. This simple
device snaps on the platen and
revolves with it. The method of
inserting alabefis clearly shown in the accompanying illustration.
Stiff cards should be fed into the machine in the usual way,
