PAUSE Self Test
This self test can be used to provide the test labels required when making adjustments to the
printer’s mechanical assemblies or to determine if any printhead elements are not working.
Figure 19 shows a sample printout.
To perform a PAUSE self test, complete these steps:
1. Turn off (O) the printer.
2. Press and hold PAUSE while turning on (I) the printer. Hold PAUSE until the first control
panel light turns off.
• The initial self test prints 15 labels at the printer’s slowest speed, and then
automatically pauses the printer. Each time
PAUSE is pressed, an additional 15 labels
print. Figure 19 shows a sample of the labels.
Figure 19 • PAUSE Test Label
• While the printer is paused, pressing
CANCEL alters the self test. Each time PAUSE is
pressed, 15 labels print at 6 in. (152 mm) per second.
• While the printer is paused, pressing
CANCEL again alters the self test a second time.
Each time
PAUSE is pressed, 50 labels print at the printer’s slowest speed
• While the printer is paused, pressing
CANCEL again alters the self test a third time.
Each time
PAUSE is pressed, 50 labels print at 6 in. (152 mm) per second.
• While the printer is paused, pressing
CANCEL again alters the self test a fourth time.
Each time
PAUSE is pressed, 15 labels print at the printer’s maximum speed.
• To exit this self test at any time, press and hold
CANCEL.

FEED Self Test
Different types of media may require different darkness settings. This section contains a
simple but effective method for determining the ideal darkness for printing bar codes that are
within specifications.
During the FEED self test, labels are printed at different darkness settings at two different print
speeds. The relative darkness and the print speed are printed on each label. The bar codes on
these labels may be ANSI-graded to check print quality.
The darkness value starts at three settings lower than the printer’s current darkness value
(relative darkness of –3) and increase until the darkness is three settings higher than the current
darkness value (relative darkness of +3).
Depending on the dot density of the printhead, seven labels are printed at each of the following
speeds:
• 203 dpi printers: 2 ips, 6 ips, and 10 ips
• 300 dpi printers: 2 ips, 6 ips, 8 ips
• 600 dpi printers: 2 ips, 4 ips
To perform a FEED self test, complete these steps:
1. Print a configuration label to show the printer’s current settings.
2. Turn off (O) the printer.
3. Press and hold FEED while turning on (I) the printer. Hold FEED until the first control
panel light turns off.
The printer prints a series of labels (Figure 20) at various speeds and at darkness settings
higher and lower than the darkness value shown on the configuration label.
