During the Print Quality Report (FEED self test), a series of 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 barcodes on these labels may be ANSI-graded to check
print quality.
During this test, one set of labels is printed at low speed, and another set is printed at the
high speed. 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).
The speed at which labels are printed during this print quality test depends on the dot
density of the printhead.
• 300 dpi printers: prints 7 labels at 51mm/sec (2 ips) and 102 mm/sec (4 ips) print
speeds.
• 203 dpi printers: prints 7 labels at 51mm/sec (2 ips) and 152 mm/sec (6 ips) print
speeds.
To perform a Print Quality Repor
t, complete these steps:
4. Print a configuration report to show the printer’s current settings. Press and hold the
FEED and CANCEL buttons for two (2) seconds to print the report.
5. Turn OFF the printer.
6. Press and hold FEED while setting the printer power to ON. Hold FEED until the
Status indicator is the only indicator lit.
The printer prints a series of labels (Figure 1) at various speeds and darkness
settings higher and lower than the darkness value shown on the configuration label.
