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 will want to monitor usage to avoid
running out part way through a transaction. When the paper is out, you must load a new roll immediately or data may be
lost!
When paper is low:
• Colored stripe appears on the receipt paper, (if paper is purchased with stripe) and indicates enough paper remains for a
small transaction.
• If paper low option is installed on the printer, the green LED flashes slowly indicating that approximately 15 feet
of paper remains. If too much paper is left on the roll, the “paper low” setting can be adjusted by entering the
configuration menu and changing the “paper low” extension setting.
When paper is out:
• Green LED flashes quickly indicating the paper must be installed.
Warning: Do not try to operate the printer or host computer if the printer runs out of paper. The printer may continue to
accept data from the host computer even though it is unable to print. Data may be lost as a result!
For instructions on how to change the receipt paper, look in Chapter 3: Setting up the Printer, “Load or change the receipt
paper” (see page 14).
Note: When changing the type of paper being used, you must set the printer to the new paper type. This is done through
the command 1D 81 m n or through the configuration menu. (See the Programming Guide for command usage or page 21
to enter configuration menu.)
Paper type grades
Type 0: Monochrome
Type 4: Two-color

Maximum Power Setting
The maximum power setting must be configured to match the power supply. The setting will be preconfigured from the
factory but may require changing if using a different power supply than the one shipped with the printer.
There are three levels of power that can be selected in the Hardware Options section of the configuration menu (see page
21 to enter the configuration menu):
Level I is the default setting for use with an external power supply.
Level II is the default setting for use with a terminal power supply.
Level III is a custom setting for use with a high-power supply.
Printhead Setting
The printhead energy rating and printer setting must match. The setting will be preconfigured from the factory but may
require changing should service to the thermal mechanism be 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 the mechanism is different from the head setting, you must enter the configuration menu and set the printhead
to match. (See the Service Guide for replacing the thermal mechanism.)
