Introduction and Overview1–2
Introduction
The T3204–20, T3204–21, T3304–20 and T3304–21 are high speed, high
capacity bar code printers designed for industrial and other high volume
applications. They feature direct thermal and thermal transfer print
technologies. The distinguishing characteristics of each printer model are
shown below in Table 1–1.
These printers are designed so all replacements and adjustments may be
easily performed, providing both a high level of performance and minimal
maintenance requirements.
The printers are factory installed with many standard bar code symbologies,
as well as a variety of font styles and sizes. Setup parameters are entered by
keying in menu choices through the secondary operator control panel, which
eliminates the need to set internal DIP switches.
The printer can be equipped with a variety of options such as a cutter, peel
and present (requires the factory-installed media internal rewind option),
adjustable media supply hub, Centronics-compatible parallel host interface,
coax/twinax host interface, on-line verification capability, DRAM expansion,
internal batch cartridge (IGP/FGL only), font and memory cartridges. There
are also additional factory installed only options available such as media
internal rewind and ribbon saver.
This manual is intended to provide the service person with all information
necessary to setup, adjust, troubleshoot and perform any required
maintenance on the printers. For information on configuration parameters
and day-to-day printer operation, refer to the Setup and Operator’s Guides
corresponding to the specific emulation installed in the printer.
NOTE: As used in this manual, the word “printer” refers to both the T3204
and T3304 except as noted below.

T3204/T3304 Printer Overview
In general terms, the printer may be divided into four main areas: the Media
Path, Printhead, Electronics and Power,and Options.
Media Path consists of the transport mechanism which moves print media
through the printer, and includes the supply and take-up hubs, motors, drive
belts and idler rollers.
Printhead contains the printhead and printhead mounting assembly, ribbon
transport, printhead adjustments, printhead home sensor and latching
mechanism.
Electronics and Power includes the i960 Printer Controller PCBA, the primary
operator’s control panel, secondary operator’s panel, secondary operator’s
panel PCBA and power supply.
Options include the Centronics-compatible parallel interface, media cutter
and tray, ribbon saver, media rewinder, peel and present mechanism,
adjustable media supply hub and memory expansion options.

Media and Ribbons
Width: 0.5 inch (12.7 mm) to 4.65 inches (118 mm)
Thickness: 0.0025 inch (0.0635 mm) to 0.0100 inch (0.254 mm)
Type: Roll-fed, die-cut continuous or fan-fold labels, tags or
tickets; most direct thermal or thermal transfer materials
Supply Roll: 8 inches (203 mm) maximum diameter on a 3.0 inch
(76.2 mm) core
Label Material: Thermal transfer plain-coated papers, vinyl, Mylar, metalized
paper, non-woven fabric, fine woven fabric, thermal-visible
light scanable paper, infrared scanable paper, thermal
ticket/tag stock, thermally sensitive plastic stock.
Thermal Ribbons: Standard widths are 25, 40, 60, 80 and 110 mm,
1476 ft. (450 m) in length.
Media Sensing: Moveable ”see-through” for die-cut labels and
reflective for tags with black striping.
NOTE: The reflective sensor mark must be carbon based. The sensor is
infrared and will not reflect off of a plain black mark.
