Tips for Avoiding Problems
Prevent overheating of the print head
Overheating of the thermal print head is one of the most common causes of printer problems. To avoid overheating do
one or more of the following:
1. Reduce the amount of solid coverage when printing receipts.
2. Reduce the time of continuous printing, or the “duty cycle.” The duty cycle is the percentage of time that the
printer can be actively printing in any sixty-second period of time. The duty cycle will vary for your printer
depending on the temperature of the room where you have set it up and the amount of print coverage, and it
is expressed as a percentage in the table below. For example, if the duty cycle is 50 percent, it means that the
printer should only print for 30 seconds out of every minute. If the duty cycle is 25 percent, the printer should
print for 15 seconds and then be idle for another 45 seconds.
3. Reduce the temperature of the room where you put the printer. Keep in mind that the temperature may also be
aected if the printer is exposed to direct sunlight, near a space heater or heat lamp, and so on.
CAUTION
If the duty cycle exceeds the limits shown in the table below, the receipt print head will heat up and shut down. This
may damage the print head.
Allowable duty cycle (measured over one minute of continuous printing)
Ambient temperature
25°C 35° C 50° C
Amount of solid coverage (77°F) (95°F) (122°F)
20% 100 % 50 % 20 %
40% 50 % 25 % 10 %
100% 20 % 10 % 4 %
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.
• “Duty cycle “ is the percentage of time that the
specied “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.
Avoid Harsh Environments
The A776II 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 dust and airborne chemicals, particularly in places like
home improvement stores, garden shops, and warehouses. In these kinds of environments you will need to make sure
that your printer is cleaned regularly to make sure it keeps working properly.
To prolong the life of your printer, we recommend regularly inspecting and cleaning the MICR read head, sensors,
carriage shaft and printer mechanisms.
Paper
CAUTION
Use of paper other than that approved by CognitiveTPG can damage the printer and void all warranties.
MICR heads
CAUTION
Make sure you don’t insert a check into a printer with a paperclip or staple attached!

Cleaning
Cleaning the printer cabinet
Clean the outside cabinet as needed, using any household cleaner made for plastics. You may want to test a small
unseen area rst. Wipe the paper compartment with a clean, damp cloth. The cabinet materials and nish are durable
and can tolerate cleaning solutions, lubricants, fuels, cooking oils, and ultraviolet light.
Cleaning the thermal print head
WARNING
Don’t touch the thermal print head, as this can cause burns.
CAUTION
Do not attempt to clean the inside of the printer with any spray cleaner. Do not try to clean the thermal print head
(except as recommended) or allow any spray to come in contact with it. This may damage the internal electronics or
thermal print head.
If the print head appears dirty, wipe it with isopropyl (rubbing) alcohol on a cotton swab or alcohol pen.
CAUTION
Do not use the rubbing alcohol to clean any other parts of the printer! This may cause damage.
27Chapter 4: Using the Printer
CAUTION
The thermal print head does not normally require cleaning when recommended paper grades are used. If you use
paper not approved by CognitiveTPG paper over an extended period, attempting to clean the thermal print head
will have little eect on the print quality and could cause jamming and other damage to the printer, voiding the
warranty
If spotty or light printing problems persist after cleaning the thermal print head, the thermal print mechanism may
need to be replaced.
Cleaning Out Paper Dust
We suggest that you remove paper dust from your printer every six months or so, using canned air or some other kind
of fan to blow the dust out of the printer.
Cleaning MICR
We suggest that you clean the contact image sensor every six months or so, using a cotton swab and rubbing alcohol.

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 tell the user that the
printer has a problem.
The following pages describe common conditions that
you could encounter and easily x yourself. A few may
require that you contact a service representative. See
“Contacting a service representative” on page 34.
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 online paper status error light and
compare the indications to the following table.
3. Test the receipt printer or slip printer as described
on page 14.
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 specications
The A776II 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 inches) wide
68 mm (2.68 inches) long
• Side insertion (minimum)
51 mm (2 inches) wide
203 mm (8 inches) long
• Single-ply forms should be on paper that is greater than 15 pounds
• 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”).
CAUTION
Do not use forms containing holes along the top or right edge.
• Forms for use with ip check
(minimum) 70 mm (2.75 inch) wide
152 mm (6 inch) long
• The slip form should be at and
without 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
aected by gluing method,
length of edge, and quality of
glue used.
c. Left edge or wide slip paper:
Skewing may occur.
The Slip sensors that activate the slip-in light use a reective photo sensor.
• Do not use paper that has holes or dark areas with low reection (less than 60% reection) at the slip sensor
location. (Area “A” in the illustration above.)
• Thin paper should be used between the top and bottom sheets of multi-part paper. Thick paper reduces the copy
capability.
• For best print quality on the bottom sheets of multipart forms, use the double-strike mode.
• If any part in a multipart form exceeds .003 inches in thickness, the remaining parts may be unreadable.

Check specications
Check specications for paper are dened by American Standards ANSI X9.13 and ANSI X9.18, and International
Standard ISO 1004.
• Minimum check size: 70 mm (2.75 inch) wide x 152 mm (6 inch) long
• Maximum check size: 95 mm (3.75 inch) wide x 222 mm (8.75 inch) long
MICR reader – additional information
• For best results the check should be at and free of curls, folds, or wrinkles (especially at the edges). Wrinkled
checks may rub against the ribbon causing them to get ink stains.
• Checks should not have paperclips or staples. Paper jams, MICR read errors, and damage to the MICR head can
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.
