Considerations for Printing the Diagnostic Print
1. You must have paper loaded
2. Use the same type of paper that the customer was using when they found the image quality prob-
lem.
3. If the customer is using non-HP paper and after the Image Quality Test you still have the same image
quality problems, change to genuine HP paper and repeat the Image Quality Test.
4. If you do not see any problems with the Image Quality Test, then the problem may not be with the
printer itself. The problem may be with the RIP or the driver for example.
However, if you do see problems with the Image Quality Test then continue with the Advanced Diagnostic
procedures which will help you to diagnose the problem.
Printing the Image Quality Service Print
1. In the Service Utilities submenu, scroll to “Diagnostic Print” and press Enter.
2. You will be given an option to print one of the four types of diagnostic prints. Use the Arrows keys to
make the selection and press the Enter key to start printing the required Diagnostic Print.
If you selected the “Others”, use the Arrow keys to make the required selection: “Visual Alignment
Diagnostics”, “Visual Paper Advanced Diagnostic”, or “Force Drop Detection”, and press the Enter
key to start printing.
