Monochrome Paper Print Density (Default)
This function makes it possible to adjust the energy level of the printhead to darken the printout or
adjust for paper variations. An adjustment should only be made when necessary. The factory setting
is 80%.
CAUTION: Choose an energy level no higher than necessary to achieve a dark printout. Failure to
observe this rule may result in a printer service call or voiding of the printer warranty. Running at a
higher energy level will reduce the printhead life.
When the printer prints high-density print lines (text or graphics), it automatically slows down.
To change the print density:
1. Enter the configuration menu. Refer to
Entering the Configuration Mode on page 10.
2. Select Set Hardware Options from the main menu.
Printer responds, Hardware Options Menu, and when scrolled prompts, Set Print Density?.
3. Select Yes.
A warning is printed, followed by the density adjustment selections.
Using the paper feed button, enter clicks for selection, then hold 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 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.
When paper is out:
Green LED flashes quickly indicating the paper must be installed.
CAUTION: 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, refer to Loading or Changing the Receipt Paper
on page 4.
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.
