Test pages
Printing test pages helps you determine whether or not the device engine and the formatter are
functioning.
NOTE Information pages also can be used to solve device issues. See Use information
pages on page 45.
Engine-test page
To verify that the device engine is functioning, print an engine-test page. To print an engine-test page,
press the engine-test-page switch (callout 1).

Figure 6-3 Locating the engine-test-page switch
The test page should have a series of horizontal lines. The test page prints from the last tray that the
device pulled from, unless the device has been turned off and then turned on again since the most recent
print job. If the device has been turned off and then on again since the most recent print job, then the
page will print from tray 2. The device will continuously print test pages until the test-page switch is
released. The device will not print a test page if it is in Sleep mode.
NOTE A damaged formatter might interfere with the engine test. If the engine test page does
not print, try removing the formatter and performing the engine test again. If the engine test is
then successful, the problem is in the formatter, the control panel, or the cable that connects
them.
