Printer Self-Tests
The printer self-tests are used to check the print quality and operation of your
printer. Your Hewlett-Packard Customer Service Engineer will typically run
these tests. For a description of each test, see page 123.
To activate a test, select it and press the ENTER key. To stop the test, press
ENTER again.
An example procedure for running the self-test “All E’s,” which determines
whether print quality is acceptable, is described in Table 19.
Note Whenever you run a self-test, the top-of-form setting is lost. You must reset
the top-of-form. See your
LineJet Printers Quick Reference Guide
