1 Maintenance Overview
TallyGenicom®6600 Cartridge Ribbon Printer (CRP) Series
TallyGenicom
®
has been the global leader in industrial printing solutions for
over 30 years, earning a reputation for designing and manufacturing leading
edge products and delivering them to market with unsurpassed service and
support.
The TallyGenicom 6600™ Line Matrix Printing Platform extends the series of
technology innovations that cement TallyGenicom’s leadership position. Line
matrix printing is TallyGenicom’s flagship technology, and it remains the
workhorse solution for supply-chain and back-office printing applications
because of its reliability, lower cost of ownership and flexibility of printing
applications.
• Most reliable printer ever – provides more up time and lower operating
costs
• Ultra capacity ribbons – deliver darker image, last longer, and costs less
to operate than other print technologies
• Integrated print management system – provides precise control over print
quality, print costs, and job planning
• Cabinet or Pedestal styles – best user access and forms handling
flexibility
• Unsurpassed ease of use – simplifies operation and enhances
productivity
There are four printer configurations:
Enclosed Cabinet
• The enclosed cabinet models provide for near silent operation, making
these printers perfectly suitable for use in the quietest of office
environments.
• Provides the best paper handling for large print runs. All paper input and
output is contained inside the cabinet and protected from bumping and
contamination.
• Highly effective combination of moveable fences and chains allows for
precise stacking all the way up to a full box of paper.
• For tougher forms that tend not to refold well, a SureStak power stacker
option is available for the enclosed cabinet models.
• Available in four print speeds – 500 line per minute (lpm), 1000 lpm,
1500 lpm, and 2000 lpm models.

18
Chapter 1 TallyGenicom® 6600 Cartridge Ribbon Printer (CRP) Series
Pedestal
• The pedestal model has a clamshell design that allows easy access to all
controls, providing faster ribbon replacements and easier paper loading.
• Oversized casters are standard making movement easy.
• Versatility to configure the paper path for either top or rear exit.
• Using the top paper exit, this printer is ideal for short print runs and easy
access to output.
• Available in three print speeds – 500 line per minute (lpm), 1000 lpm, and
1500 lpm models.
Quiet Pedestal
• This printer configuration is the same as the above Pedestal configuration
but with an enclosed input paper area with a front door, side panels, and
bottom panel to seal the input paper path.
• Provides a reduction in acoustic noise.
Zero Tear Pedestal
• Special push tractor configuration enables printing from the very first to
the very last line of a form and then tear-off with no forms lost.
• The elimination of wasted forms between jobs can yield significant
savings.
• An ideal solution for supply-chain and back-office applications.
• Available in three print speeds – 500 line per minute (lpm), 1000 lpm, and
1500 lpm models.
Order the Correct Spares
When you replace worn or damaged printer components, make sure you
order the correct spares for the model you are servicing. The next section
shows you how to identify a 6600 Cartridge Ribbon Printer.

How to Identify a 6600 Cartridge Ribbon Printer
19
How to Identify a 6600 Cartridge Ribbon Printer
A 6600 printer has a model number logo and ribbon cartridge logo on the
printer front cover. The model number is an alphanumeric code that identifies
the printer type, its housing, and its maximum rated print speed. The serial
number “C” indicates that this is a cartridge equipped printer. The model
number and serial number of the printer are on the identification label next to
the input/output ports at the rear of the printer. Figure 1 shows how to
interpret a model number.
Figure 1. How to Interpret a Model Number
The speed of printing for “real world” print jobs is affected by the interaction of
many variables and varies from print job to print job. For more information,
see “Printing Rates” on page 282.
Zero Tear Pedestal (ZTP) Printers
Zero Tear Pedestal (ZTP) printers are models equipped with special
hardware and software that permits them to print small jobs or single sheets
without losing a sheet between print jobs. A ZTP printer automatically
presents the current print line to a tear bar when it finishes printing and
presents the perforation of the last form printed to the tear bar. When it
receives more data from the host computer, the printer pulls the form down to
the print station and resumes printing.
ZTP printers are covered in Appendix E (page 403).

Printer Configuration Code
Every printer has a configuration code which specifies the printer’s cabinet
type, controller board revision level, V8 ASIC revision level, and MECA ASIC
revision level. The configuration code is included in the configuration printout.
Figure 2 shows how to interpret the printer’s configuration code.
Figure 2. How to Interpret the Printer’s Configuration Code
Forms Handling
Pedestal Models
Pedestal models provide access to printed forms from the top cover with a
tear-at-perforation edge for ejected forms or a paper exit at the rear of the top
cover. Pedestal printers also have a wireform paper tray attached to the front
of the pedestal and a wireform catch basket attached either to the back of the
pedestal or to the back of the printer top cover.
Cabinet Models
Cabinet models can be equipped with four kinds of paper stacking devices:
• The fixed paper fence is a wireform divider that separates the source
paper stack from the printed output stack, and is used in combination with
hanging chains that guide printed forms downward.
• For improved performance at higher print speeds, the chains are used
with a moveable fence called the “passive paper stacker,” which can be
positioned to match the form’s length.
• The front access paper stacker consists of a shelf that holds the input
paper and a sliding tray that receives the printed forms. The sliding tray
pulls forward, permitting the user to both load and unload paper from the
front of the printer. This option is helpful in locations where access to the
rear of the printer is limited or impossible.
• For more demanding applications, an optional power stacker is available.
(The power stacker is covered in Appendix D on page 353.)
These devices are summarized in Table 1.
