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:

1Press Menu until “Self-Test Page” appears on the display.

2Press 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).
