Built-in Tests

The printer application contains a suite of tests for regularly checking the
hardware and software, and for troubleshooting.

Because running the tests affects the operation of the printer, you can only open
the Built-in Tests interface when the system is not printing.

The test suite features:

• The organization of printing-related tasks in categories:

❒

Communications

❒

Data cards

❒

Temperatures

❒

Voltages

❒

Encoder repeatability

❒

Print-head heating

❒

Print-head filling

• A clear display of test results and the source of any failures, enabling you to

determine if printing is possible or worthwhile.

• The ability to monitor test results for specific components.

• Troubleshooting tips.

Running these tests can help identify problems in the printer hardware and
software. A large number of hardware defects (or near-defects) warns you of
possible printing problems, either for current or future jobs.

Stratasys recommends running the built-in tests in the following cases:

as a routine test, once every two weeks

as a system check, before major (long) jobs

as needed, for troubleshooting
