Chapter 3 Operating the printer
Using the paper feed button, enter clicks for the selection, and then hold the button down at least 1
second to validate.
When to change the receipt paper
Change the paper when it is near the end of the roll or out. When the paper is low, you should monitor usage
to avoid running out partway through a transaction. When the paper is out, you must load a new roll
immediately or data may be lost.
When paper is low:
A colored stripe appears on the receipt paper (if paper is purchased with a stripe) and indicates enough paper
remains for a small transaction.
When paper is out:
The green LED flashes quickly indicating the paper must be installed.
IMPORTANT: Do not try to operate the printer or POS computer if the printer runs out of paper. The printer
may continue to accept data from the POS computer even though it is unable to print. Data may be lost as a
result.
For instructions on how to change the receipt paper, see Loading or changing the receipt paper on page 6.
Maximum power setting
The maximum power setting must be configured to match the power supply. The setting is preconfigured but
may require changing if using a different power supply than the one shipped with the printer. There are three
levels of power, besides auto, that can be selected in the Hardware Options section of the configuration menu
(see Entering the configuration mode on page 8):
●
Auto
●
Level I (55 W)
●
Level II (75 W)
●
Level III (90 W)
Printhead setting
The printhead energy rating and printer setting must match. The setting is preconfigured but may require
changing if service to the thermal mechanism is required. The Head Setting on the diagnostic printout must
match the letter marked on the front right of the thermal mechanism. Whenever the thermal mechanism is
replaced, if the letter on the mechanism is different from the head setting, you must enter the configuration
menu and set the printhead to match.
Preventing printhead overheating
There are restrictions on the duty cycle because of the heat generated by the thermal printhead when
printing solid blocks (regardless of the length of the block in relation to the print line). The restrictions are
ambient temperature, the percentage of time (measured against one minute) of continuous solid printing,
and the amount of coverage.
The ambient temperature may be affected by factors such as direct exposure to sun or close proximity to
heating elements.
When to change the receipt paper
11
IMPORTANT: When the duty cycle exceeds the limits shown in the following table, the receipt printhead will
heat up and shut down. This may damage the printhead.
To avoid this problem, do one or a combination of the following:
1.
Reduce the amount of coverage.
2.
Reduce the time of continuous solid printing.
3.
Reduce the ambient temperature.
Allowable duty cycle* (measured over one minute of continuous printing)

*Duty Cycle - Percentage of time that the specified “Amount of Solid Coverage” can be printed during a oneminute period of time. For example, at 20% solid coverage and 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.

Maintenance guidelines
Cleaning the printer
Clean the outside of the cabinet as needed to remove dust and finger marks. Use any household cleaner made
for plastics. Test it first on a small unseen area. Clean the printer paper bucket with a clean, damp cloth.
The cabinet materials and finish are durable and resistant to the following items:
●
Cleaning solutions
●
Cooking oils
●
Lubricants
●
Ultraviolet light
●
Fuels
Cleaning the thermal printhead
IMPORTANT: Do not clean the inside of the printer with any cleaner. Do not allow cleaning spray to come in
contact with the thermal printhead. Damage to the internal electronics or thermal printhead could occur.
NOTE: The thermal printhead does not normally require cleaning when recommended paper grades are
used. If non-recommended paper is used over an extended period, attempting to clean the printhead will
have little effect on the print quality.
1.
Turn off the printer and POS computer.
2.
Unplug the printer from the POS computer and the cash drawer, if connected.
3.
Wipe the printhead with a cotton swab moistened with rubbing alcohol.
IMPORTANT: Do not use rubbing alcohol to clean any internal parts of the printer other than the printhead.
Damage will occur.
If spotty or light printing problems persist after cleaning the thermal printhead, the entire thermal
mechanism may need to be replaced.
IMPORTANT: Using non-recommended paper over an extended period of time can result in printhead
failure. See Qualified paper grades on page 20 for paper specifications.

A
Troubleshooting
Diagnostics
The printer performs three primary diagnostic tests that provide useful information about the printer’s
operating status:
●
Startup diagnostics, performed during the printer’s startup cycle
●
Runtime diagnostics
●
Remote diagnostics, maintained during normal operation and reported in the print test
Startup diagnostics
When the printer receives power or performs a hardware reset, it automatically performs the startup
diagnostics (also known as level 0 diagnostics) during the startup cycle. The printer:
●
Turns off the motors
●
Performs boot CR check of the firmware ROM, tests external SRAM, tests EEPROM, and tests main
program CRC.
Failure causes startup diagnostics to stop; the printer beeps and the LED flashes a set number of times,
indicating the nature of the failure. The following table describes the specific tone and LED sequences.
LED Behavior
Failure
One blink
Boot CRC error
Two blinks
RAM failure
Three blinks
EEPROM failure
Four blinks
Memory initialization failure
To resolve the problem:
●
Check to see if paper is present
●
Return the knife to the home position; failure causes a fault condition
●
Check if the rear cover is closed; failure does not interrupt the startup cycle
When the startup diagnostics are complete, the printer makes a two-tone beep (low then high frequency), the
paper feed button is enabled, and the printer is ready for normal operation.
If the printer has not been turned on before, or a new EEPROM has been installed, the default values for the
printer functions will be loaded into the EEPROM during startup.
Runtime diagnostics
Runtime diagnostics (sometimes called level 2 diagnostics) run during normal printer operation. When the
following conditions occur, the printer automatically turns off the appropriate motors and disables printing to
prevent damage to the printer.
