The Universal HP-100NI, HP-200NI and HP-200 hand printers are designed for
the hand application of printed data on cartons, bags and other flat, porous surface
materials
The HP-100NI and HP-200NI machines are non-indexing or continuous roll de-
signs. The HP-200 machine is an indexing or spot printing design which allows for
accurate print registration and eliminates duplication of data.
RIBtype® PRINTING DIES
Universal Coders are designed to use
RIBtype® printing dies which have a molded
rib backing. The ribs on the back of the die
snap into mating ribs in the ribtype drum cover
on the print drum as shown in Figure 1. Al-
though there are several competitive rib backed
die systems available, it is very important to
note that they are not all made to the same
specifications and are not interchangeable.
Dies are available in many standard character styles and sizes in sets containing
a combination of individual alphabetic and numeric characters or in sets of nu-
meric characters only. These character sets or “sorts” can be used to make up
text messages and code numbers as necessary. Dies are also available in
“logo” form in which a complete text message is produced on a single piece of rib
backed rubber. Logo dies are much faster to change and normally produce better
print quality since they are more dimensionally stable than individual characters
when installed on the print drum.
Universal also offers RIBtype® Metric Die systems for use in countries where
metric character sizes are the standard. The Metric dies are thicker and the rib
spacing differs slightly from the standard printing dies therefore the two versions
are not compatible. To accommodate the differences, the print drums for Metric
dies are machined to a slightly different diameter from the U.S. versions.
The coder model numbers on Metric coders will have a “-T” suffix and the Metric
Drum Covers have a distinct pink color.

MICROCELL ROLLS: The standard ink rolls shipped with Universal Hand Print-
ers are made from reticulated urethane foam. This material is one of the most
durable ink roll materials available and with proper care should last in excess of
one year before replacement becomes necessary. Microcell rolls should be inked
with Universal No. 1150 porous coder ink only. It is extremely important to fol-
low the inking instructions or roll performance will be adversely affected.
INK ROLLS & INKS
SPECIFICATIONS
XF NEOPRENE ROLLS: Universal’s XF Neoprene Ink Rolls are made from an
extra firm density neoprene material. While not quite as durable as Microcell, the
extremely fine cell structure of these rolls provides exceptionally good print quality,
particularly when using small character printing dies. Due to their greater ability to
compensate for slight die thickness variations, these rolls are also recommended
to correct print quality problems when multiple lines of text are required.
Although these Hand Printers are not designed for production use with alcohol
base marking inks, the XF Neoprene Ink Rolls are compatible with a variety of
alcohol base inks. For limited use applications, slow drying alcohol base inks can
be used on the XF Neoprene ink rolls for marking on Non-Porous surfaces such as
metal, plastic, glass, etc. Please note that the alcohol in non-porous inks will evapo-
rate rapidly leaving the rolls dry and hard in a relatively short period of time. After
use with alcohol base inks, the rolls should be immediately removed from the coder
and stored in an air tight container.
OPTIONAL TYPE BLOCKING KITS
When using small individual characters with
only a two or three rib backing, an optional Type
Blocking Kit (stock no. UR-BK) should be used
to support the leading and trailing ends of the
type as shown.
Characters which have only a 2 or 3 rib back-
ing do not have the stability of the larger char-
acter sizes when snapped into the drum cover.
Adding the rib backed type blocks on both ends
of the code will provide added stability and pre-
vent the characters from shifting during print-
ing. The Type Blocks are not as thick as the
Type and will not pick up ink from the Ink Roll. FIGURE 2

QUICK START
PRE-INKING THE MICROCELL INK ROLL
Universal Hand Printers are shipped from the factory fully assembled and, unless
otherwise specified, include a dry Microcell Ink Roll. The Ink Roll must be manu-
ally pre-inked prior to use. The initial inking of a dry roll is a critical process. The
following instructions will guide you through the inking and installation process and
have your coder ready to use in a few minutes.
Microcell Ink Rolls are designed for use with Uni-
versal #1150 Ink for marking on porous surfaces.
Inks will stain clothing, furniture, carpeting and your hands. Rubber gloves
should be worn during the following procedures.
1 - Fill a clean dry container with enough ink
to allow the ink roll to fully submerge.
2 - Carefully place the ink roll into the ink.
Do not force the roll to submerge. The
top surface of the roll must remain dry
during this process.
The roll should be allowed to float, undisturbed, in
the container of ink. Leaving the top surface of the
roll dry allows air to escape as the ink is absorbed
from the bottom. When the roll sinks under the
surface of the ink, it is fully saturated.
3 - Remove the ink roll from the container by
inserting a screwdriver through the core.
4 - Roll the ink roll over paper towels or a piece
of scrap cardboard to remove excess ink.
The rolls will be excessively saturated after removal
from the container. Remove enough ink from the
roll so the surface does not appear wet. Use a
clean paper towel to blot the ink from the ends of
the core before installation on the coder.
Let the excess ink drip into the container.

Grip the Ink Roll Eccentric Adjusting Knob with one
hand. Insert a 3/16” hex wrench through the ac-
cess hole in the side frame of the coder and turn the
Ink Roll Axle counterclockwise until loose. Pull the
Ink Roller Axle out through the access hole.
6 - Remove the Ink Roller Axle from the coder.
7 - Position the ink roll between the two side
frames of the coder and insert the Ink Roll
Axle through the Ink Roll core.
8 - Install the printing dies by aligning the ribs
on the die back with the matching grooves
on the print drum.
5 - Rotate the Ink Roll Eccentric Knob until the
Ink Roll Axle is at its farthest position away
from the print drum.
While gripping the Ink Roll Eccentric Adjusting Knob
with one hand, tighten the Ink Roll Axle using the 3/
16” hex wrench.
QUICK START
In this position, the ink roll will not contact the print
drum during installation.
Start with one end and press the die into the print
drum cover until the die is fully engaged.
Tip to make die installation easier when installing larger logo dies: Moisten a
sponge with water containing a few drops of liquid dish detergent. Lightly moisten
the back of the printing die and then immediately press the die into the drum cover.
Do not apply too much liquid or the dies will slip during printing. Never apply any
other lubricants such as oil or silicone or the dies will not hold properly.

9 - Adjust the Ink Roller Eccentric Knob to a
position where the ink roll just contacts the
die faces when the print drum is rotated.
Ink should only be applied to the die face, not the
sides or backing of the die. Excessive contact pres-
sure will result in an excessively wet and smudged
impression.
RE-INKING THE MICROCELL INK ROLL
10 - Your coder is now ready for use.
After the initial inking process, the Microcell Ink
Roll can be re-inked by carefully squirting a small
amount of ink on the roll surface. It is best to
apply very small amounts of ink down the length
of the roll in multiple places rotating the roll
after each pass. Do not apply an excess amount
of ink or print quality will suffer.

MAINTENANCE
REPLACING THE DRUM COVERING
1 - Lay the coder on it’s side as shown and
using a 5/64” hex wrench, loosen the set
screw in the end of the top Side Frame.
Do not loosen the set screw in the bottom side frame.
Replacing the Drum Covering requires removal of the print drum. The following
steps explain the process. For Indexing Coders, see Page 12 under Index Spring
Replacement for Print Drum removal instructions.
2 - Remove the two button head screws which
hold the Side Frame to the Back Frame us-
ing a 3/32” hex wrench.
3 - Lift the Side Frame off the coder.
4 - Pull the Print Drum off the Axle.
A slight wiggling action of the Side Frame may help
in this process.
Be careful not to lose the thin brass washers lo-
cated on either side of the print drum.
