Warranty
The Ink Jet System (excluding printhead) carries a 365 day limited warranty from the date of shipment.
The Printhead carries a 180 day limited warranty from the date of shipment. For all terms and
conditions, refer to the full warranty statement packaged with the Ink Jet Printer.
Use of the wrong fluid type in the system is not covered under warranty.
Introduction
NOTE: This manual describes operation of both the porous (water-based) and non-porous (alcohol-
based) printers. Water-based fluids can NOT be used in non-porous (alcohol-based) systems. Alcohol-
based fluids can NOT be used in porous (water-based) systems.
The ink jet printing system is compact and easy to use. It prints a single line of alphanumerics at
speeds as slow as 5 fpm and as fast as 250 fpm. Print quality is excellent and it offers message
control and printhead flexibility. There are three font choices: 5-dot (3/8”), 7-dot (1/2”) and 7-dot bold
and it can print with multiple fonts on the same line. The ink is contained in a 13 fluid ounce (392 ml)
pressurized canister. Ink canisters can be replaced without interrupting production. You can choose
from six high-visibility ink colors: black, blue, green yellow, orange and red.
The printhead has patented I.V. (Integrated Valve) print technology and individual dot control
capability, resulting in better print quality. Ink does not touch the internal electronics of the printhead,
ensuring long-term operational reliability. It has flexible mounting and a dual-axis 180° rotation that
allows printing on the side, top or bottom of cartons as well as printing on inclined surfaces. There are
two built-in photosensors that measure speed and direction and are located in the face of the
printhead. The printhead requires daily maintenance measures (purging) performed at the beginning
of the work day, and following an extended shutdown of a week or more.
The controller offers a QWERTY keypad with ALT key for multiple key combinations, separate
number keys, icon function keys, four keys for cursor control and four LEDs (that warn or show status
of power, photosensor, print mode and low ink). It has autocode capabilities that allow for
Julian/Gregorian date, time sequential numbering, shift, item count, pallet/batch count and expiration
date. It also has message storage capabilities of 99 fifty-character messages and an “ink out” alarm.
Tubing comes attached to the controller and connects to the back of the printhead. A power supply
unit connects to the controller and sets in a holster on the mounting bracket.

Loading Ink B1
Do not stop printing when you run low on ink. The system has enough ink in its delivery system to
continue printing until you install a fresh can.
1
1 Unscrew the old can and set aside.
2
2 Remove the cap from the new can, invert and screw into
the ink receptacle. Make sure that the ink can adapter and
the receiver on the ink delivery system are the same color.
Black adapter and black receiver indicate water-based
porous.
Red adapter and red receiver indicate alcohol-based
non-porous.
3
3 Dispose of the old can in accordance with local, state and
federal regulations.
CAUTION
1. Use only water-based
porous inks, identified
with black fittings, for
porous printers with
black receivers.
2. DO NOT SHAKE THE

pressure drops below normal operating
pressure. This causes ink to collect on the
face plate. The face plate should be
cleaned every time the ink can is replaced.
CAUTION
1. Use only alcohol-based
non-porous inks, identified
with red fittings, for non-
porous printers with red
receivers.
