1. The Diagnostic Print requires A2 or C size media so you must have media loaded (roll or sheet) that is this size or larger.

2. Use the same type of media that the customer was using when they experienced the print quality problem.

3. Use the same print mode the customer was using when they experienced the print quality problem.

4. If the customer is using non-HP media and after the Diagnostic Print you still have the same print quality problems, change to genuine HP media and repeat the Diagnostic Print.

5. Study each of the test patterns in the order that they are shown i.e. 1 through 5.

6. If you do not see any problems with the Diagnostic Print, then the problem may not be with the Printer itself. The problem may be with the RIP or the driver for example (See Driver print quality configuration).

However if you do see problems with the Diagnostic Print then continue with the following procedures which will help you to diagnose the problem.
