Pattern Test
The pattern test is the basic verification of the printer’s ability to produce
quality models, since it demonstrates the condition of the nozzles in the
print heads. Make sure, therefore, that you perform this test weekly, and
whenever you suspect a printing problem.
To perform the pattern test:
1. Make sure that the build tray is empty.
2. Prepare a sheet of pink paper—A ‐ 4 or Letter size.
3. In the printer, tape the pink paper to the surface left of the build tray.
4. Press
F3
, or open the Options menu and select
Pattern Test
.

5. If the build tray is not clear, click
No
in the following dialog box.
This lowers the build tray, so that models on the tray are not damaged.

The printer prints a series of lines on the test paper (see next figure).

6. Carefully inspect the test paper to see if there are missing lines.
Too many missing lines, especially if they are in the same area,
indicates that the quality of printing when producing models will be
poor. If this is the case, see “Improving Print Quality,” below.
Note: Acceptable model quality is subjective, and depends on the type
and scale (size) of the models produced . As a rule, however, more than 10
missing lines in one area of a column is considered unacceptable.
