How to Use the Self-Test Page

The self-test page lets you know whether the HP OfficeJet is operating

properly. It lists current, default front-panel settings, and tells whether the

ADF is attached properly.

To print a self-test page:

Press Menu until “Self-Test Page” appears on the display.

Press Select/Resume.

The test page has a set of lines that should appear unbroken, and colored

bars that should appear solid. The intensity of the colors varies,

depending on the type of paper you are using (that is, plain paper,

HP Premium Inkjet Paper, and so on).
