ColorPOS
two-color receipt printing plus a drop in
validation print station. The B780 provides maximum
flexibility, performance, and reliability.
It consists of two specialized printers in one compact
package: a two-color thermal printer on top that prints
receipts, and an impact slip printer to print on forms and
checks that you insert. Built-in MICR check validation is
an optional feature of the B780 printer.
The B780 fits easily in spaces where no other hybrid
printer can and connects to most host computers via the
Dual 9-pin /USB interface or 25-pin RS-232 interface.
Powered USB and Ethernet interface are also available.
B780 UG00001 5/04 B780 Two-Color Thermal/Impact Hybrid Printer: User Guide
The printer’s standard command set allows it to work
with software written for TPG or other compliant
printers. A variety of sensors enables the printer to
communicate its status to the host computer. The printer
also has an electronic journal feature.
The easy-to-use thermal printer requires no ribbon or
ink cartridge. Load new paper by simply opening the
TM
clamshell
receipt cover and dropping in a new roll.
The impact printer provides the power and flexibility to
print on checks or multi-part forms up to four plies, in a
wide variety of sizes and orientations.
This section describes the printer’s features and options
in more detail.

Audible Beeps
After power is applied or after reset, the printer normally
emits a single beep. This indicates that the printer has
successfully completed its startup and self-test routine.
If, after startup or reset, the beeping continues in a
single, double, or triple pattern, an internal failure has
occurred. Please call your service representative.
Available printer configurations
There are several configurations of the printer, depending on the combination of desired options.

Getting Started
Before setting up the printer, be sure you read and understand each of the sections in this chapter. The sections are
presented in the sequence that they should be performed.
6.6"
13
11.4"
Choose a location
The B780 printer being only 6.5 inches wide requires
very little counter space and may be set on or near the
host computer. With the RS-232C interface, you can
place the printer up to 50 feet (with the USB interface up
to 15 feet) from the host computer and power supply.
Do not place the printer in any dusty environment or
anywhere that spillage of drinks or other liquids can
occur.
Place the printer on a level surface, and make sure there
is enough room to open the receipt cover to change the
paper and to open the front cover to change the impact
printer’s ribbon cassette.
6.5"
Be sure to leave adequate space at the rear of the printer
for connecting and accessing the cables.
If the printer has a built in Magnetic Ink Character
Recognition (MICR) check reader, you may need to
make additional adjustments to the printer’s location.
Devices such as CRT monitors or large metal surfaces
can affect the printer’s magnetic field and cause
intermittent check reading errors. Be sure to locate the
printer away from such sources of interference.

Tips for Avoiding Problems
Prevent overheating of the printhead
Overheating of the thermal printhead is one of the most common causes of serious printer
problems.
To prevent overheating, certain duty cycle restrictions need to be applied because of the heat
generated by the thermal printhead, particularly when it is printing logos.
Certain limits we can apply are: ambient temperature, the percentage of time of continuous
solid printing (measured against one minute), and the percentage amount of coverage.
To avoid overheating do one or more of the following:
1 Reduce the amount of coverage.
2 Reduce the time of continuous solid printing.
3 Reduce the ambient temperature.
Keep in mind that the ambient temperature may be adversely affected by direct exposure to sunlight or close
proximity to other sources of heat.
Caution: If the duty cycle exceeds the limits shown in the
table below, the receipt printhead will heat up and shut
down. This may damage the printhead.
Allowable duty cycle (measured over one minute of continuous printing)
Amount of solid coverage Ambient temperature
25°C 35° C 50° C
(77°F) (95°F) (122°F)
20% 100% 50% 20%
40% 50% 25% 10%
100% 20% 10% 4%
Duty cycle
Percentage of time that the specified
“Amount of solid coverage” can be printed
during a one minute period of time.
Example: at 20% solid coverage,
35° C temperature, a 50% duty
cycle is to be used, resulting in
30 seconds of printing and
30 seconds without printing.
For reference:
• A typical receipt with text (contains some blank
spaces) is approximately 12% dot coverage.
• A full line of text characters (every cell on the line has
a character in it) is approximately 25% dot coverage.
• Graphics are approximately 40% dot coverage.
• Barcodes are approximately 50% dot coverage.
• A solid black line is 100% dot coverage.
Avoid Harsh Environments
The B780 printer is a durable piece of equipment and can withstand a range of physical environments. However, the
printer’s internal mechanical components are vulnerable to airborne contaminants, particularly in certain harsh areas,
such as home improvement stores, garden shops, and warehouse environments. The printer can become inoperative
rapidly in these kinds of environments, if routine cleaning is not performed.
To prolong the serviceability of your printer in these harsh environments, we recommend regular periodic inspection
and general cleaning of the MICR read head, sensors, carriage shaft and both printer mechanisms.
B780 Two-Color Thermal/Impact Hybrid Printer: User Guide B780 UG00001 5/04
Chapter 5: Troubleshooting
The simple design of B780 requires virtually no periodic servicing. However, if problems do occur, they can usually
be diagnosed readily by checking the light status indicators, below, then referring to appropriate section of the
Troubleshooting guide on the pages that follow.
Status Indicators
The on-line, paper status, error light is the light to the
rear, on the top edge of the printer. It may be the first
indication that something is wrong.
The light closer to the front on the right edge of the
printer indicates that a form is inserted properly. It does
not indicate an error.
For some unexpected conditions, the printer
communicates the information to the host computer and
relies on the application to indicate what the condition is.
The information on the following pages describes
common conditions that you could encounter and easily
fix yourself. A few may require that you contact a service
representative.
35Chapter 5: Troubleshooting
You should be able to correct many of the conditions
locally without calling for service. However, if a condition
persists, contact a service representative. See “Contacting
a service representative” at the end of this chapter.
Typical Remedy Procedure
If an unexpected condition has occurred, take the
following general steps:
1 Cycle the power of the printer and note its behavior.
2 Check the on-line, paper status, error light and
compare its behavior to the following table.
3 Test the receipt printer or slip printer by printing a
sample test print as described elsewhere in this
document.
4 Determine if the condition is with the thermal receipt
printer or the impact slip printer and refer to the tables
on the following pages.

Forms specifications
The B780 prints on single- or multiple-part forms in the slip station (up to four-part forms).
Forms and slips must meet the following requirements:
• Front insertion (minimum):
51 mm (2.00") wide
68 mm (2.68") long
• Side insertion (minimum):
51 mm (2.0") wide
203 mm (8.0") long
• Single-ply forms should be on paper that is greater
than 15 pounds
Slip forms - recommendations
• The slip form should be flat and void of curls or
wrinkles, especially at the top.
• Considerations for glued edges on slip paper:
a No glue on bottom edge.
b Right or top edge: Paper feeding and insertion
are affected by gluing method, length of edge,
and quality of glue used.
c Left edge or wide slip paper: Skewing may
occur.
• Multiple-part forms (up to four parts) should be no
thicker than 0.40 mm (0.014") and a minimum thickness
of 0.08 mm (0.003").
Important: Do not use forms containing holes along
the top or right edge.
• Forms for use with flip check (minimum)
70 mm (2.75") wide
152 mm (6.00") long
6 mm
(0.236")
Slip edge
Paper feed
direction
Paper holes and
low reflection
prohibited areas
A
The Slip sensors that activate the slip-in light use a reflective photo sensor.
• Do not use paper that has holes or dark areas with low reflection (less than 60% reflection) at the slip sensor
location. (Area “A” in the illustration above.)
• Thin paper should be used between the top and bottom sheets of multi-ply paper. Thick paper reduces the copy
capability.
• For best print quality on bottom sheets of multipart forms, use the double-strike mode.
• If any ply in a multipart form exceeds .003 inches in thickness, the remaining plies may be unreadable.
B780 Two-Color Thermal/Impact Hybrid Printer: User Guide B780 UG00001 5/04
Check specifications
45
Check specifications for paper are defined by American
Standards ANSI X9.13 and ANSI X9.18, and
International Standard ISO 1004.
• Minimum check size: 70 mm (2.75") wide x 152 mm
(6.00") long
• Maximum check size: 95 mm (3.75") wide x 222 mm
(8.75") long
MICR reader – additional information
• For best results the check should be flat and free of
curls, folds, or wrinkles (especially at the edges).
Wrinkled checks may rub against the ribbon causing
them to become ink-stained.
• Checks must be void of clips or staples. Paper jams,
MICR read errors, and/or MICR head damage could
occur.
• Immediately release the check once the printer starts
to feed it. Failure to release the check could skew it,
causing paper jams and MICR read errors.
