Engine diagnostics
Print engine test pages to help determine whether the product and the formatter are functioning. If the
formatter is damaged, it can interfere with the engine test. If the engine test page does not print, try
removing the formatter, and then perform the engine test again. If the engine test is successful, the
problem is likely with the formatter.
NOTE: Information pages also help solve product issues. See the product user guide for information
about printing information pages.
Engine test button
NOTE: The product has a firmware engine test button that is activated by opening and closing the
print-cartridge door in a specific pattern.
Perform an engine test

3. Turn the product on. Wait for the product to reach the ready state.
4. Open, and then close the print cartridge door five times at an interval of about two seconds to
activate the internal engine test button.
5. If the engine test is successful, an engine test page prints with a series of horizontal lines across
the page.
