CHAPTER 2
OPERATING INSTRUCTIONS
This chapter tells you how to operate the SPINWRITER. It
describes the printer controls, shows you how to load the
paper, and. gives you procedures for SPINWRITER operation.
2.1 PRINTER CONTROLS
Figure 2-1 illustrates the printer controls you will be using.
The numbers in the following paragraphs correspond to the numbers in the figure.
(1) Platen knobs. These allow the platen to be rotated
manually to insert paper and position it properly.
The right knob provides variable platen action; when
you push the knob in, the platen rolls freely in
either direction. You can change the position of the
writing line by using this variable platen function.
(2) Copy control lever. This lever moves the platen forward or backward to compensate for different form
thicknesses (number of carbons). Place it all the way
forward for a single copy, and all the way rearward
for an original and seven carbon copies. Intermediate
positions provide for form thicknesses between these
two extremes. When printing on a form of several
copies with this lever moved toward the rear, you may
have to increase the print hammer intensity for optimum print quality by changing the impression control
switch (see Figure 2-1, 9).
0
(3) & (4) Pressure bail levers and pressure bail. The
pressure bail holds the paper against the platen for
optimum print quality and quietness. To insert paper,
pull the bail forward, away from the platen, by moving
one of the levers. When using a pin-feed platen or a
forms-tractor assembly, move the pressure bail forward
away from the platen. The pin-feed paper clamps or
the forms-tractor assembly hold the paper in the optimum position for proper operation.
(5) Ribbon Selector Switch. The ribbon selector switch is
located under the top cover under the ribbon cartridge. Place the switch to the left for multi-strike
ribbons and to the right for red/black fabric ribbons. The switch can be used in either position for
the all-black fabric ribbon.

2.2 PAPER LOADING INSTRUCTIONS
The SPINWRITER has three different types of paper feed:
friction-feed, pin-feed, and vertical type tractor paper feed.
When loading paper, refer to the procedure below that applies
to the particular type of paper feed for your machine . Figure
2-2 shows rear paper feed path. Figure 2-3 shows the paper
feed path for bottom feed.
NOTE
If you use a single sheet of paper in
the SPINWRITER, raise the paper guide
to deactivate the paper out switch.

CHAPTER 3
MAINTENANCE AND REPLACEMENT PROCEDURES
This chapter suggests ways to help you maintain high quality
printing. It includes procedures for replacing ribbons,
thimbles, and other items.
3.1 MAINTAINING HIGH QUALITY PRINT
To ensure high print quality, proper attention should be given
to such items as various printer control settings, paper
quality, ribbon quality, etc. Here are several suggestions you
can use to maintain high print quality.
• Select the proper ribbon.... multi-strike ribbons give
you sharper impressions than a fabric ribbon. Dried or
malfunctioning ribbons will give you a faded print
image.
• Choose high quality paper to obtain the best print
image.... sharp, crisp characters and maximum
black-and-white contrast. Poor quality paper may
result in punctured paper or broken images.
• Select the proper copy control lever setting....all the
way forward for a single copy and moved rearward for
additional copies.
• Set the impression control switch for the best print
image .... low for small typefaces (12 pitch) , medium for
normal impact pressure, and high for large typefaces or
multiple copies.
• Set the space pitch setting so that it matches the
pitch of the thimble being used .... a mismatch will
result in cramped or widely spaced characters.
• Align paper correctly with enough tension so that it
does not tear or wrinkle.
• Keep the platen clean and free of mars and scratches.
•
Establish quality standards for different jobs...
similar jobs will be prepared in a similar manner and
require similar quality.
3.2 RIBBON CARTRIDGE REPLACEMENT
a. Turn POWER off and raise the top cover.
b. Hold the ribbon cartridge lightly; at the same time
press the two locking tabs which hold the cartridge in
place ; remove the cartridge upward ( see Figure 3-1).
c. Rotate the manual feed knob on the new cartridge in the
direction indicated by the arrow to establish tension
on the ribbon.
d. Place the new ribbon cartridge over the mounting plate,
and insert the ribbon between the card holder and card
holder bracket.
e. Insert the ribbon in the ribbon sensor if a
multi - strike ribbon is used ( see Figure 3-2).
f. Press the ribbon cartridge downward until the locking
tabs engage.
NOTE
Rotate the manual feed knob on the
cartridge in the direction indicated by
the arrow to ensure proper seating.
g. Place tension on the ribbon
(see c.).
h. Close the top cover and restore ac power.
3.3 PRINT THIMBLE REPLACEMENT
a. Turn POWER off and raise the cover.
b. Remove the ribbon cartridge (see 3.1).
c. Push hammer lock lever toward the platen ( Figure 3-2);
at the same time , tilt the hammer cover toward the
front.
d. Slide the lock piece , at the center of the print thimble, horizontally and then to the upright position.
NOTE
When handling print thimble, hold it at
the base, to avoid possible damage to
the character type areas.
