HP DesignJet 5000 Series Printers Service Manual

The Printer contains an internal Diagnostic Print to help you 
diagnose the possible source of any print quality defects. The 
Diagnostic Print is divided into five numbered parts:

1 Primary colors specifically designed to diagnose banding problems.

2 Color to color alignment.

3 Bidirectional alignment to check alignment when printing 

bidirectionally.

4 Vertical line straightness.

5 Nozzle print test to check each Printhead nozzle in a Printhead.

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.

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