Electrical Safety
This printer is inspected and listed by recognized national testing laboratories, such as
Underwriters Laboratories, Inc. (UL) in the U.S.A. and Canadian Standards Association (CSA) in
Canada. Listing of a product by a national testing laboratory indicates that the product is designed
and manufactured in accordance with national requirements intended to minimize safety hazards.
IBM equipment meets a very high standard of safety in design and manufacture. Remember,
however, that this product operates under conditions of high electrical potentials and heat
generation, both of which are functionally necessary.

Maintenance Overview
About the Printer
The entire system architecture of an IBM* 6400 line matrix printer is
contained on one circuit board. The use of DRAM and flash memory on this
board permits rapid access to stored printer emulations and fast processing
of print data. A variable-speed shuttle and half-step paper control enables the
printer to print a wide variety of high-volume jobs with minimum maintenance
and maximum reliability.
Although technologically advanced, the printer is easy to use. The operator
can select every printer function at the control panel or by sending printer
control codes in the data stream from the host computer.
This is also an excellent graphics printer, with optional features that simplify
the creation of dot images. The IGP** and Code V** Printronix** emulations
are simple but versatile graphics programming languages that load into flash
memory.
The IBM 6400 Series Printer Family
The IBM 6400 Line Matrix Printer family consists of pedestal mount and floor
cabinet models that print at different speeds, as shown in Table 1. The print
speeds listed in Table 1 are the maximum speeds attainable under certain
conditions. Actual print speed is determined by the interaction of many
variables. For more information, refer to the discussion of Printing Rates in
Appendix B, page 342.
Maintenance Overview
13
Models that print 475, 500, 800, 900, and 1000 lpm are available in floor
cabinet and pedestal housings. Models that print 1200, 1400, and 1500 lpm
are available only in floor cabinets.

The microprocessor of the Data Controller unit on the CMX controller board
runs at 25 MHz or 40 MHz, depending on printer model. This means there
are two kinds of CMX controller board for IBM 6400 printers, used as shown
in Table 1. The 40 MHz controller board, however, is backwards compatible
in all models that use the 25 MHz board.
Maintenance Overview
Printer Evolution
IBM 6400–050, –P50, –010, –P10, and –015 printers use a redesigned
shuttle frame assembly, hammer bank, and ribbon guides which are not
compatible with earlier models. These models use the CMX 040 controller
board, which has a 40 MHz clock speed on the Data Controller unit.
How to Identify the Printer
The model number of the printer indicates printer family, speed, and type of
enclosure. (See Figure 1.)

Important Maintenance Notes
Failure to observe the following guidelines can result in damage to the
equipment.
To ensure the best performance of the printer, remember these important
maintenance concepts when you service the printer:
♦ Do not adjust the platen gap unless the original shuttle frame assembly
or platen has been replaced with a new or rebuilt unit, or unless
instructed to do so in the troubleshooting chapter.
♦ Never bend or “tweak” hammer springs. Always handle hammer springs
by the thick mounting base. The hammer springs and hammer tips are
delicate and precisely aligned.
♦ Use only the ribbons specified in Appendix B. Use of incorrect ribbons
can lead to ink migration problems, degraded print quality, and expensive
damage to the printer.
♦ Do not close the forms thickness lever too tightly. Closing the forms
thickness lever too tightly can lead to smearing, degraded print quality,
paper jams, and damage to the platen and shuttle assembly.

Preventive Maintenance
Cleaning the Printer
Aside from normal replenishment of paper and ribbons, the only preventive
maintenance required for the printer is periodic cleaning.
Because operating conditions vary widely, the user must determine how often
to clean the printer.
There is no guarantee that the user will clean the printer regularly, however,
so you should clean the printer whenever you are called to service it.
DANGER:
<2> Switch off printer power and unplug the printer power cord before
cleaning the printer.
ATTENTION
Do not use abrasive cleaners, particularly on the window.
Do not drip water into the printer. Damage to the equipment will result.
Do not spray directly onto the printer when using spray solutions
(spray the cloth, then apply the dampened cloth to the printer).
Do not vacuum circuit boards.
Preventive Maintenance
29
Cleaning the Exterior
1. Power off the printer.
2. Disconnect the AC power cord from the power source.
3. Wipe the outside of the enclosure with a clean, lint-free cloth dampened
(not wet) with water and a mild detergent or window cleaning solution.
4. Dry the enclosure with a clean, lint-free cloth.
5. Clean the inside of the printer, as described below.
Cleaning the Interior
1. Power off the printer.
2. Disconnect the AC power cord from the power source.
3. Open the printer cover.
4. Remove paper from the printer.
5. Remove the ribbon.
6. Using a soft-bristled, non-metallic brush, wipe paper dust and ribbon lint
off the tractors, shuttle cover assembly, base casting, and ribbon guides.
Vacuum up the residue.
7. Wipe the splined shaft and the ribbon guides with a soft cloth.
8. Vacuum up dust or residue that has accumulated inside the lower
cabinet.
9. Wipe the interior of the lower cabinet with a clean, lint-free cloth
dampened with water and a mild detergent or window cleaning solution.
10. Dry the cabinet interior with a clean, lint-free cloth.
11. Clean the shuttle frame assembly, as described below.
