8. Troubleshooting
Test Method 1
A printout using test method 1 shows the
printer’s parameters and settings, for
example: date, time, program version,
communication settings and which
typefaces are available.
1. Switch off the printer.
2. Press the print button, but do not
release it.
3. Switch on the printer without releasing
the print button.
4. Keep the print button depressed until
the printer starts printing the test
pattern.
5. Then, release the print button.
Test Pattern
The method 1 test print produces a pattern
with three different fields. These fields
rovide information about: p
• Whether all the dots on the print
head are functioning correctly.
If one or more dots are missing, a
distinct white line appears in the
test pattern.
• Whether the roller is perfectly
cylindrical and is in the correct
position.
• Whether the print head is
completely parallel with the roller.
The test pattern is lighter in those
areas where the roller is not
perfectly cylindrical or where the
print head is not completely parallel
with the roller.
